+	This patch brings over a few features from MirBSD:
+	* -fhonour-copts
+	  If this option is not given, it's warned (depending
+	  on environment variables). This is to catch errors
+	  of misbuilt packages which override CFLAGS themselves.
+	* -Werror-maybe-reset
+	  Has the effect of -Wno-error if GCC_NO_WERROR is
+	  set and not '0', a no-operation otherwise. This is
+	  to be able to use -Werror in "make" but prevent
+	  GNU autoconf generated configure scripts from
+	  freaking out.
+	* Make -fno-strict-aliasing and -fno-delete-null-pointer-checks
+	  the default for -O2/-Os, because they trigger gcc bugs
+	  and can delete code with security implications.
+
+	This patch was authored by Thorsten Glaser <tg at mirbsd.de>
+	with copyright assignment to the FSF in effect.

+	This patch brings over a few features from MirBSD:
+	* -fhonour-copts
+	  If this option is not given, it's warned (depending
+	  on environment variables). This is to catch errors
+	  of misbuilt packages which override CFLAGS themselves.
+	* -Werror-maybe-reset
+	  Has the effect of -Wno-error if GCC_NO_WERROR is
+	  set and not '0', a no-operation otherwise. This is
+	  to be able to use -Werror in "make" but prevent
+	  GNU autoconf generated configure scripts from
+	  freaking out.
+	* Make -fno-strict-aliasing and -fno-delete-null-pointer-checks
+	  the default for -O2/-Os, because they trigger gcc bugs
+	  and can delete code with security implications.
+
+	This patch was authored by Thorsten Glaser <tg at mirbsd.de>
+	with copyright assignment to the FSF in effect.

+I talked to Andrew about what files he changed in GCC and created and
+tested this new patch.  Andrew also mentioned changing some assembly
+files in glibc but I don't see any use of '.section .note.GNU-stack' in
+any assembly files in glibc (for any platform) so I wasn't planning on
+creating a glibc to add them to mips glibc assembly language files.
+
+OK to check in this patch?

+	This patch brings over a few features from MirBSD:
+	* -fhonour-copts
+	  If this option is not given, it's warned (depending
+	  on environment variables). This is to catch errors
+	  of misbuilt packages which override CFLAGS themselves.
+	* -Werror-maybe-reset
+	  Has the effect of -Wno-error if GCC_NO_WERROR is
+	  set and not '0', a no-operation otherwise. This is
+	  to be able to use -Werror in "make" but prevent
+	  GNU autoconf generated configure scripts from
+	  freaking out.
+
+	This patch was authored by Thorsten Glaser <tg at mirbsd.de>
+	with copyright assignment to the FSF in effect.

+I talked to Andrew about what files he changed in GCC and created and
+tested this new patch.  Andrew also mentioned changing some assembly
+files in glibc but I don't see any use of '.section .note.GNU-stack' in
+any assembly files in glibc (for any platform) so I wasn't planning on
+creating a glibc to add them to mips glibc assembly language files.
+
+OK to check in this patch?

+	  This option group includes support for the 'nsswitch' facility.
+	  With this option group enabled, all EGLIBC functions for
+	  accessing various system databases (passwords and groups;
+	  networking; aliases; public keys; and so on) consult the
+	  '/etc/nsswitch.conf' configuration file to decide how to handle
+	  queries.
+
+	  With this option group disabled, EGLIBC uses a fixed list of
+	  services to satisfy queries on each database, as requested by
+	  configuration files specified when EGLIBC is built.  Your
+	  'option-groups.config' file must set the following two
+	  variables:
+
+	  EGLIBC_OPTION_EGLIBC_NSSWITCH_FIXED_CONFIG
+
+		Set this to the name of a file whose contents observe the
+		same syntax as an ordinary '/etc/nsswitch.conf' file.  The
+		EGLIBC build process parses this file just as EGLIBC would
+		at run time if EGLIBC_NSSWITCH were enabled, and
+		produces a C library that uses the nsswitch service
+		libraries to search for database entries as this file
+		specifies, instead of consulting '/etc/nsswitch.conf' at run
+		time.
+
+		This should be an absolute filename.  The EGLIBC build
+		process may use it from several different working
+		directories.  It may include references to Makefile
+		variables like 'common-objpfx' (the top of the build tree,
+		with a trailing slash), or '..' (the top of the source tree,
+		with a trailing slash).
+
+		The EGLIBC source tree includes a sample configuration file
+		named 'nss/fixed-nsswitch.conf'; for simple configurations,
+		you will probably want to delete references to databases not
+		needed on your system.
+
+	  EGLIBC_OPTION_EGLIBC_NSSWITCH_FIXED_FUNCTIONS
+
+		The EGLIBC build process uses this file to decide which
+		functions to make available from which service libraries.
+		The file 'nss/fixed-nsswitch.functions' serves as a sample
+		configuration file for this setting, and explains its syntax
+		and meaning in more detail.
+
+		This should be an absolute file name.  The EGLIBC build
+		process may use it from several different working
+		directories.  It may include references to Makefile
+		variables like 'common-objpfx' (the top of the build tree,
+		with a trailing slash), or '..' (the top of the source tree,
+		with a trailing slash).
+
+		Be sure to mention each function in each service you wish to
+		use.  If you do not mention a service's function here, the
+		EGLIBC database access functions will not find it, even if
+		it is listed in the EGLIBC_OPTION_EGLIBC_NSSWITCH_FIXED_CONFIG
+		file.
+
+	  In this arrangement, EGLIBC will not use the 'dlopen' and
+	  'dlsym' functions to find database access functions.  Instead,
+	  libc hard-codes references to the service libraries' database
+	  access functions.  You must explicitly link your program
+	  against the name service libraries (those whose names start
+	  with 'libnss_', in the sysroot's '/lib' directory) whose
+	  functions you intend to use.  This arrangement helps
+	  system-wide static analysis tools decide which functions a
+	  system actually uses.
+
+	  Note that some nsswitch service libraries require other option
+	  groups to be enabled; for example, the EGLIBC_OPTION_EGLIBC_INET
+	  option group must be enabled to use the 'libnss_dns.so.2'
+	  service library, which uses the Domain Name System network
+	  protocol to answer queries.

+		getutent_r
+		getutid
+		getutid_r
+		getutline
+		getutline_r
+		logwtmp

+
+config EGLIBC_OPTION_EGLIBC_UTMPX
+	bool "POSIX access functions for 'utmp' login records"

+	  This option group includes the POSIX functions for reading and

+	  '/var/run/utmp').  The POSIX functions operate on 'struct
+	  utmpx' structures, as opposed to the family of older 'utent'
+	  functions, which operate on 'struct utmp' structures.

+config EGLIBC_OPTION_POSIX_REGEXP
+	bool "Regular expressions"
+	default y
+	help
+	  This option group includes the POSIX regular expression
+	  functions, and the associated non-POSIX extensions and
+	  compatibility functions.
+
+	  With EGLIBC_OPTION_POSIX_REGEXP disabled, the following functions are
+	  omitted from libc:
+

+
+	  Furthermore, the compatibility regexp interface defined in the
+	  <regexp.h> header file, 'compile', 'step', and 'advance', is
+	  omitted.
+
+
+config EGLIBC_OPTION_POSIX_REGEXP_GLIBC
+	bool "Regular expressions from GLIBC"
+	default y
+	select EGLIBC_OPTION_POSIX_REGEXP
+	help
+	  This option group specifies which regular expression
+	  library to use.  The choice is between regex
+	  implementation from GLIBC and regex implementation from
+	  libiberty.  The GLIBC variant is fully POSIX conformant and
+	  optimized for speed; regex from libiberty is more than twice
+	  as small while still is enough for most practical purposes.
+
+
+config EGLIBC_OPTION_POSIX_WIDE_CHAR_DEVICE_IO
+	bool "Input and output functions for wide characters"
+	default y
+	select EGLIBC_OPTION_POSIX_C_LANG_WIDE_CHAR
+	help
+	  This option group includes functions for reading and writing
+	  wide characters to and from <stdio.h> streams.
+
+	  This option group includes the following functions:
+
+		fgetwc        fwprintf      putwchar      vwscanf
+		fgetws        fwscanf       ungetwc       wprintf

+		fputws        getwchar      vfwscanf
+		fwide         putwc         vwprintf
+
+	  This option group further includes the following unlocked
+	  variants of the above functions:
+
+		fgetwc_unlocked           getwc_unlocked
+		fgetws_unlocked           getwchar_unlocked
+		fputwc_unlocked           putwc_unlocked
+		fputws_unlocked           putwchar_unlocked
+					
+	  Note that the GNU standard C++ library, 'libstdc++.so', uses
+	  some of these functions; you will not be able to link or run
+	  C++ programs if you disable this option group.
+
+	  This option group also affects the behavior of the following
+	  functions:
+
+		fdopen
+		fopen
+		fopen64
+		freopen
+		freopen64
+
+	  These functions all take an OPENTYPE parameter which may
+	  contain a string of the form ",ccs=CHARSET", indicating that
+	  the underlying file uses the character set named CHARSET.
+	  This produces a wide-oriented stream, which is only useful
+	  when the functions included in this option group are present.
+	  If the user attempts to open a file specifying a character set
+	  in the OPENTYPE parameter, and EGLIBC was built with this
+	  option group disabled, the function returns NULL, and sets
+	  errno to EINVAL.

+ * This file defines five types of data structures: singly-linked lists,

+ *
+ * A singly-linked list is headed by a single forward pointer. The
+ * elements are singly linked for minimum space and pointer manipulation
+ * overhead at the expense of O(n) removal for arbitrary elements. New
+ * elements can be added to the list after an existing element or at the
+ * head of the list.  Elements being removed from the head of the list
+ * should use the explicit macro for this purpose for optimum
+ * efficiency. A singly-linked list may only be traversed in the forward
+ * direction.  Singly-linked lists are ideal for applications with large
+ * datasets and few or no removals or for implementing a LIFO queue.
+ *
+ * A list is headed by a single forward pointer (or an array of forward
+ * pointers for a hash table header). The elements are doubly linked
+ * so that an arbitrary element can be removed without a need to
+ * traverse the list. New elements can be added to the list before
+ * or after an existing element or at the head of the list. A list
+ * may only be traversed in the forward direction.
+ *
+ * A simple queue is headed by a pair of pointers, one the head of the
+ * list and the other to the tail of the list. The elements are singly
+ * linked to save space, so elements can only be removed from the
+ * head of the list. New elements can be added to the list after
+ * an existing element, at the head of the list, or at the end of the
+ * list. A simple queue may only be traversed in the forward direction.
+ *
+ * A tail queue is headed by a pair of pointers, one to the head of the
+ * list and the other to the tail of the list. The elements are doubly
+ * linked so that an arbitrary element can be removed without a need to
+ * traverse the list. New elements can be added to the list before or
+ * after an existing element, at the head of the list, or at the end of
+ * the list. A tail queue may be traversed in either direction.
+ *
+ * A circle queue is headed by a pair of pointers, one to the head of the
+ * list and the other to the tail of the list. The elements are doubly
+ * linked so that an arbitrary element can be removed without a need to
+ * traverse the list. New elements can be added to the list before or after
+ * an existing element, at the head of the list, or at the end of the list.
+ * A circle queue may be traversed in either direction, but has a more
+ * complex end of list detection.
+ *
+ * For details on the use of these macros, see the queue(3) manual page.

+Subject: [PATCH] Add PowerPC soft-float support
+
+Some PowerPC CPUs (e.g. Freescale MPC85xx) have a completely different
+instruction set for floating point operations (SPE).
+Executing regular PowerPC floating point instructions results in
+"Illegal instruction" errors.
+
+Make it possible to run these devices in soft-float mode.

+Subject: [PATCH] stdio: implement assignment-allocation "m" character
+
+The latest POSIX spec introduces a "m" character to allocate buffers for
+the user when using scanf type functions.  This is like the old glibc "a"
+flag, but now standardized.  With packages starting to use these, we need
+to implement it.
+
+for example:
+	char *s;
+	sscanf("foo", "%ms", &s);
+	printf("%s\n", s);
+	free(s);
+This will automatically allocate storage for "s", read in "foo" to it,
+and then display it.
+
+I'm not terribly familiar with the stdio layer, so this could be wrong.
+But it seems to work for me.

+Subject: [PATCH] libc: add fallocate() and fallocate64()
+
+We add the Linux-specific function fallocate() which allows the user to
+directly manipulate allocate space for a file.  fallocate() can operate
+in different modes, but the default mode is equivalent to posix_fallocate()
+which is specified in POSIX.1.
+
+Recent releases of e2fsprogs 1.42.11 and above expect fallocate64() to be
+available.

+Allow use of immedate values as the 6th syscall argument. Otherwise we must

+Subject: Rules.mak: MIPS64: Select correct interpreter
+
+gcc (eg 4.7.3) hardcodes the MIPS64 interpreters like this:
+(see gcc/config/linux.h and gcc/config/mips/linux64.h)
+
+o32: UCLIBC_DYNAMIC_LINKER "/lib/ld-uClibc.so.0"
+n32: UCLIBC_DYNAMIC_LINKERN32 "/lib32/ld-uClibc.so.0"
+n64: UCLIBC_DYNAMIC_LINKER64 "/lib/ld64-uClibc.so.0"
+
+The existing check for MIPS64 in uClibc is wrong because it does
+not respect the selected ABI
+
+We fix this by explicitely checking the selected ABI instead of the
+selected MIPS variant.

+
+    mips: Remove duplicate macro definitions
+    
+    The INLINE_SYSCALL, INTERNAL_SYSCALL*, and internal_syscall* macros
+    are defined for MIPS in both libc/sysdeps/linux/mips/sysdep.h and
+    libc/sysdeps/linux/mips/bits/syscalls.h.  The macros are the same
+    in both cases except that syscalls.h defines internal_syscalls[567]
+    the same for N32 and N64 ABIs and has a different definition for O32.
+    I believe that is correct.  The sysdep.h header uses the O32 versions
+    for N32 and has different definitions for N64.  I think that is wrong
+    and that N32 and N64 should share the same definition (modulo the
+    type 'long' vs. 'long long' for the arguments.  This setup (from
+    sysdep.h) now agrees with what glibc has.
+    
+    I am not positive about which header (sysdep.h vs syscalls.h) is
+    really the right one to have these definitions in but using sysdep.h
+    seems to work for all my builds.

+commit 2952c70804b48bb5c87eea21df5e401969dc4ec1
+Author: Kevin Cernekee <cernekee@gmail.com>
+Date:   Tue Jun 5 15:05:20 2012 -0700
+
+    MIPS: Use $a0 instead of $v0 for __syscall_error() argument
+    
+    $a0 is saved across _dl_runtime_resolve(); $v0 is not.  Unfortunately,
+    __syscall_error() uses $v0 for its argument, not $a0 as is the MIPS ABI
+    standard.  This means that if lazy binding was used for __syscall_error(),
+    the errno value in $v0 could get corrupted.
+    
+    The problem can be easily seen in testcases where syscalls in librt fail;
+    when librt tries to call __syscall_error() in libc, the argument gets
+    lost and errno gets set to a bogus value:
+    
+        # ./tst-mqueue1 ; echo $?
+        mq_receive on O_WRONLY mqd_t did not fail with EBADF: Unknown error 2004684208
+        1
+        # ./tst-mqueue2 ; echo $?
+        mq_timedreceive with too small msg_len did not fail with EMSGSIZE: Unknown error 1997360560
+        1
+        # ./tst-mqueue4 ; echo $?
+        mq_timedsend did not fail with ETIMEDOUT: Unknown error 2008747440
+        1
+    
+    When _dl_runtime_resolve() was taken out of the equation, the same test
+    cases passed:
+    
+        # LD_BIND_NOW=y ./tst-mqueue1 ; echo $?
+        0
+        # LD_BIND_NOW=y ./tst-mqueue2 ; echo $?
+        0
+        # LD_BIND_NOW=y ./tst-mqueue4 ; echo $?
+        0
+    
+    Changing __syscall_error() to look at $a0 instead of $v0 fixed the
+    problem.
+    
+    (Note that there is also a "__syscall_error.c" file which presumably
+    uses the standard C calling conventions, but I do not think it is used
+    on MIPS.)

+    libc: mips: Fix setjmp/longjmp for MIPS64 N64 ABI
+    
+    When booting a Linux system with qemu-system-mips64 the execution
+    of $(pwd) in the ash shell triggers a segmentation fault. Ash uses
+    setjmp/longjmp for exception handling.
+    
+    After looking at the glibc implementation,
+    I found some differences, with this patch tries to resolve.
+    Now the system boots up fine and no segmentation faults occur.
+    
+    The global pointer should be restored and the types for the
+    register values should be wide enough.
+

+Date: Mon, 01 Oct 2012 05:12:54 +0000
+Subject: libc/sysdeps: add __kernel_long and __kernel_ulong
+
+Linux 3.4 added __kernel_long_t and __kernel_ulong_t and various
+exported header files were updated to use these new types. Add the
+definitions for __kernel_long_t and __kernel_ulong_t to the relevant
+kernel_types.h headers.
+
+This change was automated with the following scriptlet
+
+  git grep --name-only 'typedef.*__kernel_old_dev_t' \
+    | xargs sed -i '/typedef.*__kernel_old_dev_t/ a\
+  typedef long\t\t__kernel_long_t;\
+  typedef unsigned long\t__kernel_ulong_t;'
+
+Whitespace in arm, avr32, hppa, sparc was then manually fixed up.
+
+Signed-off-by: Chris Packham <chris.packham@alliedtelesis.co.nz>
+--
+Here's a cleaned up patch which should get the whitespace right. I'm a
+bit iffy about the sparc changes they make sense to me but it's not a
+platform I have access to.
+
+I can break this up per arch or per maintainer if requested.

+Subject: Rules.mak: Fix setting arch native bit
+
+fix breakage from 603af30d
+
+Removing the whitespace from findstring for 64 bit architectures has
+bad consequences since powerpc would be a match in powerpc64 and sparc
+would also be a match in sparc64.
+That doesn't make them 64 bits in reality causing general breakage.

+From fd355bc1dbcb794ae1abf0fad1459e28d8567ba0 Mon Sep 17 00:00:00 2001
+From: Hiroaki KAWAI <kawai@stratosphere.co.jp>
+Date: Fri, 19 Apr 2013 01:09:35 +0000
+Subject: eventfd.h: Use new "bits/" scheme for arch-specific flags
+
+As in timerfd.h, eventfd.h needs arch-specific definition files.
+alpha, mips and sparc needs separate file, all the other arch
+will use common definition.
+
+This problem is already fixed in glibc.
+
+Also sanitize and provide bits for hppa.
+Make sure not to install the new bits/eventfd unless eventfd support is
+enabled.
