This commit adds support for Linux 4.19 kernel, various cleanups
listed below.
Drop 170-cisco-hack.patch as these devices never seems to have been
supported.
Unset kernel symbols:
* CONFIG_CAVIUM_CN63XXP1=y
No supported hardware uses CN63XXP1 and it causes "slight decrease in
performance"
Source: https://cateee.net/lkddb/web-lkddb/CAVIUM_CN63XXP1.html
* CONFIG_USB_OCTEON_EHCI=y
CONFIG_USB_OCTEON_OHCI=y
Deprecated
Source: https://cateee.net/lkddb/web-lkddb/USB_OCTEON_EHCI.html
https://cateee.net/lkddb/web-lkddb/USB_OCTEON_OHCI.html
Removed kernel symbols:
* # CONFIG_ARCH_HIBERNATION_POSSIBLE=y
* CONFIG_ARCH_SUSPEND_POSSIBLE=y
These are not in if you do a vanilla config of a MIPS Octeon kernel
and I can't find any references about support on this platform.
* # CONFIG_BOOTPARAM_HUNG_TASK_PANIC is not set
* CONFIG_BOOTPARAM_HUNG_TASK_PANIC_VALUE=0
No need to have this in by default, not defined in most other targets
* CONFIG_CRASH_CORE=y
Can't find any documentation why this should be enabled by default
* CONFIG_DEBUG_INFO=y
Set by https://github.com/openwrt/openwrt/blob/master/config/Config-kernel.in#L134
* CONFIG_DEBUG_SPINLOCK=y
No need to have this in by default
* CONFIG_DEFAULT_HUNG_TASK_TIMEOUT=120
Already set by default
Source: https://cateee.net/lkddb/web-lkddb/DEFAULT_HUNG_TASK_TIMEOUT.html
* CONFIG_DETECT_HUNG_TASK=y
No need to have this in by default, not defined in most other targets
* CONFIG_HAVE_DEBUG_KMEMLEAK=y
No need to have this in by default, not defined in most other targets
* CONFIG_HAVE_DEBUG_STACKOVERFLOW=y
No need to have this in by default
* CONFIG_HAVE_IDE=y
None of the supported devices have IDE
* CONFIG_HZ=250
* # CONFIG_HZ_100 is not set
* CONFIG_HZ_250=y
This is broken with generic config
* CONFIG_KALLSYMS=y
No need to have this in by default, not defined in most other targets
* CONFIG_KEXEC=y
* CONFIG_KEXEC_CORE=y
No need to have this in by default, not defined in most other targets
* CONFIG_HAVE_KVM=y
No need to have this in by default
* CONFIG_SCHED_DEBUG=y
No need to have this in by default, not defined in most other targets
* CONFIG_SYSFS_DEPRECATED=y
Deprecated symbol
Source: https://cateee.net/lkddb/web-lkddb/SYSFS_DEPRECATED.html
* CONFIG_SYSFS_DEPRECATED_V2=y
Discouraged usage in general
Source: https://cateee.net/lkddb/web-lkddb/SYSFS_DEPRECATED_V2.html
* CONFIG_UNINLINE_SPIN_UNLOCK=y
No need to have this in by default, not defined in most other targets
Source: https://github.com/openSUSE/kernel/blob/master/lib/Kconfig.debug#L1137
* CONFIG_ZLIB_INFLATE=y
No need to have this in by default, not defined in most other targets
