[PATCH] No arch-specific strpbrk implementations

2006-04-11T13:18:40+00:00

While cleaning up parisc_ksyms.c earlier, I noticed that strpbrk wasn't
being exported from lib/string.c.  Investigating further, I noticed a
changeset that removed its export and added it to _ksyms.c on a few more
architectures.  The justification was that "other arches do it."

I think this is wrong, since no architecture currently defines
__HAVE_ARCH_STRPBRK, there's no reason for any of them to be exporting it
themselves.  Therefore, consolidate the export to lib/string.c.

[PATCH] Don't pass boot parameters to argv_init[]

2006-03-31T20:18:53+00:00

The boot cmdline is parsed in parse_early_param() and
parse_args(,unknown_bootoption).

And __setup() is used in obsolete_checksetup().

	start_kernel()
		-> parse_args()
			-> unknown_bootoption()
				-> obsolete_checksetup()

If __setup()'s callback (->setup_func()) returns 1 in
obsolete_checksetup(), obsolete_checksetup() thinks a parameter was
handled.

If ->setup_func() returns 0, obsolete_checksetup() tries other
->setup_func().  If all ->setup_func() that matched a parameter returns 0,
a parameter is seted to argv_init[].

Then, when runing /sbin/init or init=app, argv_init[] is passed to the app.
If the app doesn't ignore those arguments, it will warning and exit.

This patch fixes a wrong usage of it, however fixes obvious one only.

[PATCH] for_each_possible_cpu: sh

2006-03-31T20:18:50+00:00

for_each_cpu() actually iterates across all possible CPUs.  We've had mistakes
in the past where people were using for_each_cpu() where they should have been
iterating across only online or present CPUs.  This is inefficient and
possibly buggy.

We're renaming for_each_cpu() to for_each_possible_cpu() to avoid this in the
future.

This patch replaces for_each_cpu with for_each_possible_cpu.

[PATCH] unify PFN_* macros

2006-03-27T16:44:48+00:00

Just about every architecture defines some macros to do operations on pfns.
 They're all virtually identical.  This patch consolidates all of them.

One minor glitch is that at least i386 uses them in a very skeletal header
file.  To keep away from #include dependency hell, I stuck the new
definitions in a new, isolated header.

Of all of the implementations, sh64 is the only one that varied by a bit.
It used some masks to ensure that any sign-extension got ripped away before
the arithmetic is done.  This has been posted to that sh64 maintainers and
the development list.

Compiles on x86, x86_64, ia64 and ppc64.

[PATCH] kill include/linux/platform.h, default_idle() cleanup

2006-03-24T15:33:21+00:00

include/linux/platform.h contained nothing that was actually used except
the default_idle() prototype, and is therefore removed by this patch.

This patch does the following with the platform specific default_idle()
functions on different architectures:
- remove the unused function:
  - parisc
  - sparc64
- make the needlessly global function static:
  - arm
  - h8300
  - m68k
  - m68knommu
  - s390
  - v850
  - x86_64
- add a prototype in asm/system.h:
  - cris
  - i386
  - ia64

[PATCH] more for_each_cpu() conversions

2006-03-23T15:38:17+00:00

When we stop allocating percpu memory for not-possible CPUs we must not touch
the percpu data for not-possible CPUs at all.  The correct way of doing this
is to test cpu_possible() or to use for_each_cpu().

This patch is a kernel-wide sweep of all instances of NR_CPUS.  I found very
few instances of this bug, if any.  But the patch converts lots of open-coded
test to use the preferred helper macros.

[PATCH] sh: machine_halt()/machine_power_off() cleanups

2006-02-01T16:53:20+00:00

machine_halt() managed to trigger the soft lockup detection due to not
disabling interrupts before going to sleep, so correct that.

machine_power_off() should be using pm_power_off, which lets us drop the
board-specific hacks from here.

[PATCH] sh: convert voyagergx to platform device, drop sh-bus

2006-02-01T16:53:20+00:00

Trivial patch updating the voyagergx cchip code to reference a platform device
instead, now that the dma mask is taken care of.  Given this, there's no
longer any reason to drag around the SH-bus code, so kill that off entirely.
