Linker command lines are order-sensitive.
Move linker options -Lfoo -lfoo from LDFLAGS to LDLIBS and place this new
variable after the objects to link. This resolves build errors in xenpagin
and blktap with recent toolchains.
rename SHLIB_CFLAGS to SHLIB_LDFLAGS
rename LDFLAGS_* to LDLIBS_*
move LDFLAGS usage after CFLAGS in CC calls
remove stale comments in xenpaging Makefile

This patch eliminate the global variables in libxenctrl (used for
logging and error reporting).
Instead the information which was in the global variables is now in a
new xc_interface* opaque structure, which xc_interface open returns
instead of the raw file descriptor; furthermore, logging is done via
xentoollog.
There are three new parameters to xc_interface_open to control the
logging, but existing callers can just pass "0" for all three to get
the old behaviour.
All libxc callers have been adjusted accordingly.
Also update QEMU_TAG for corresponding qemu change.

Add an option that will set up the buffers and listen for updates,
but will not enable tracing. This is useful if you have hacks
in Xen to enable tracing at key points (for example, debugging a
shadow bug).

When interrupted, first disable tracing, then read through the records
one last time.
Without this patch, it's possible to get traces which interact (such
as runstate changes) on processors with higher numbers, while missing
the corresponding traces generated on lower-numbered processors.

In the current xentrace configuration, xentrace buffers are all
allocated in a single contiguous chunk, and then divided among logical
cpus, one buffer per cpu. The size of an allocatable chunk is fairly
limited, in my experience about 128 pages (512KiB). As the number of
logical cores increase, this means a much smaller maximum per-cpu
trace buffer per cpu; on my dual-socket quad-core nehalem box with
hyperthreading (16 logical cpus), that comes to 8 pages per logical
cpu.
This patch addresses this issue by allocating per-cpu buffers
separately.

xentrace_format cannot use "0x016x" format as we expect.
It show only %(N) as "0x016x" format, not as "%(N+1)08x%(N)08x".
So I fixed tools/xentrace/formats by using "%(N+1)08x%(N)08x" format.
Also I added some TRC_PV entries.

If you use -MMD -MF then the correct .o filename is written to the
.*.d file as the compiler driver arranges everything. This was done
in 19010:275abe1c5d24 for the hypervisor.
In this patch we do the same elsewhere in the xen-unstable tree,
particularly tools/. Specifically:
* Change tools/Rules.mk to add -MMD -MF ... to CFLAGS and set DEPS.
* Remove -Wp,-MD... from every other Makefile
* Remove setting of DEPS from every other Makefile
* Ensure that every Makefile says -include $(DEPS)
* Ensure that every Makefile's clean target removes $(DEPS)
Some Makefiles were already halfway there, but often for a different
variable name eg PROG_DEP. The variable name is now standardised in
Rules.mk as DEPS.
I have done a test build with this change, on Debian etch.

Xen tracing some times ago used to put values of type 'long' into the
trace buffer. This has changed to uint32_t. Some trace points log
virtual addresses, which get cropped to 32bit in this case. There were
some inline functions to handle at least PF_XEN and VMEXIT, which
caused a lot of code duplication. The attached patch fixes several
issues:
1. fix and extend tools/xentrace/formats
2. Fix xentrace_format to handle up to 7 parameters
3. create convenience macros to properly log long values
4. remove the inline functions in hvm/trace.h and replace them by macros
5. Change the CPUID trace to work correctly
6. group HVM trace points enable mechanism
I used a similar approach as in PV tracing with bit 8 indicating 64bit
pointers.

It was previously assert'ing when it hit 4G.
Also, because the trace buffer is not a power of 2 in size,
using modulo arithmetic to address the buffer does not work
when the index wraps around 2^32.
This patch fixes both issues, and as a side effect, removes all
integer division from the hypervisor side of the trace mechanism.
