powerpc: Fix endian issue in setup-common.c

2013-12-13T04:48:34+00:00

During on LE boot we see:

    Partition configured for 1073741824 cpus, operating system maximum is 2048.

Clearly missing a byteswap here.

powerpc: Move local setup.h declarations to arch includes

2013-10-30T05:00:31+00:00

Move the few declarations from arch/powerpc/kernel/setup.h
into arch/powerpc/include/asm/setup.h.  This resolves a
sparse warning for arch/powerpc/mm/numa.c which defines
do_init_bootmem() but can't include the setup.h header
in the prior path.

Resolves:
arch/powerpc/mm/numa.c:998:13:
        warning: symbol 'do_init_bootmem' was not declared.
                 Should it be static?

code now.

powerpc/watchdog: move booke watchdog param related code to setup-common.c

2012-07-11T12:44:03+00:00

Currently, BOOKE watchdog code for checking "wdt" and "wdt_period" is
in setup_32.c, it cannot be used in 64-bit, so move it to a common place
setup-common.c, which will be shared by 32-bit and 64-bit.

Also, replace the simple_strtoul with kstrtol.

fadump: Invalidate the fadump registration during machine shutdown.

2012-02-22T23:50:03+00:00

If dump is active during system reboot, shutdown or halt then invalidate
the fadump registration as it does not get invalidated automatically.

fadump: Convert firmware-assisted cpu state dump data into elf notes.

2012-02-22T23:50:01+00:00

When registered for firmware assisted dump on powerpc, firmware preserves
the registers for the active CPUs during a system crash. This patch reads
the cpu register data stored in Firmware-assisted dump format (except for
crashing cpu) and converts it into elf notes and updates the PT_NOTE program
header accordingly. The exact register state for crashing cpu is saved to
fadump crash info structure in scratch area during crash_fadump() and read
during second kernel boot.

powerpc: various straight conversions from module.h --> export.h

2011-10-31T23:30:44+00:00

All these files were including module.h just for the basic
EXPORT_SYMBOL infrastructure.  We can shift them off to the
export.h header which is a way smaller footprint and thus
realize some compile time gains.
