target/octeon: Add Linux 4.19 support
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 Signed-off-by: Daniel Engberg <daniel.engberg.lists@pyret.net>
