[WATCHDOG] mv64x60_wdt: Add arch/powerpc platform support

2007-07-24T21:16:02Z

Add support for arch/powerpc, specifically for the prpmc2800 platform. Signed-off-by: Dale Farnsworth Signed-off-by: Wim Van Sebroeck

[WATCHDOG] mv64x60_wdt: set up platform_device in platform code

2007-07-24T18:56:35Z

The driver previously registered its platform device data in its own init function--that's bogus. Move that code to platform-specific code in arch/ppc. This is being done so that the platform code can decide at runtime whether to initialize this driver or not. Signed-off-by: Dale Farnsworth Signed-off-by: Wim Van Sebroeck

[POWERPC] Fix ARCH=ppc builds

2007-07-22T11:30:58Z

The recent signal rework broke ARCH=ppc builds with the following error: CC arch/powerpc/kernel/signal.o arch/powerpc/kernel/signal.c: In function Âdo_signalÂ: arch/powerpc/kernel/signal.c:142: error: implicit declaration of function Âset_dabrÂ make[1]: *** [arch/powerpc/kernel/signal.o] Error 1 This fixes it by including a function prototype in asm-ppc/system.h.

[PATCH] sched: sched_cacheflush is now unused

2007-07-19T19:28:35Z

Since Ingo's recent scheduler rewrite which was merged as commit 0437e109e1841607f2988891eaa36c531c6aa6ac sched_cacheflush is unused. Signed-off-by: Ralf Baechle Signed-off-by: Ingo Molnar

mm: remove ptep_test_and_clear_dirty and ptep_clear_flush_dirty

2007-07-17T17:22:59Z

Nobody is using ptep_test_and_clear_dirty and ptep_clear_flush_dirty. Remove the functions from all architectures. Signed-off-by: Martin Schwidefsky Cc: Hugh Dickins Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

page table handling cleanup

2007-07-16T16:05:36Z

Kill pte_rdprotect(), pte_exprotect(), pte_mkread(), pte_mkexec(), pte_read(), pte_exec(), and pte_user() except where arch-specific code is making use of them. Signed-off-by: Jan Beulich Cc: Andi Kleen Cc: Christoph Hellwig Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

PCI: remove pci_dac_dma_... APIs

2007-07-11T23:02:11Z

Based on replies to a respective query, remove the pci_dac_dma_...() APIs (except for pci_dac_dma_supported() on Alpha, where this function is used in non-DAC PCI DMA code).

PCI: Use a weak symbol for the empty version of pcibios_add_platform_entries()

2007-07-11T23:02:07Z

I'm not sure if this is going to fly, weak symbols work on the compilers I'm using, but whether they work for all of the affected architectures I can't say. I've cc'ed as many arch maintainers/lists as I could find. But assuming they do, we can use a weak empty definition of pcibios_add_platform_entries() to avoid having an empty definition on every arch.

Rework ptep_set_access_flags and fix sun4c

2007-06-16T20:16:16Z

Some changes done a while ago to avoid pounding on ptep_set_access_flags and update_mmu_cache in some race situations break sun4c which requires update_mmu_cache() to always be called on minor faults. This patch reworks ptep_set_access_flags() semantics, implementations and callers so that it's now responsible for returning whether an update is necessary or not (basically whether the PTE actually changed). This allow fixing the sparc implementation to always return 1 on sun4c.
