2007-10-11[MIPS] Make facility to convert CPU types to strings generally available.Ralf Baechle

2007-10-11[MIPS] Switch from to_tm to rtc_time_to_tmRalf Baechle
This replaces the MIPS-specific to_tm function with the generic rtc_time_to_tm function. The big difference between the two functions is that rtc_time_to_tm uses epoch 70 while to_tm uses 1970, so the result of rtc_time_to_tm needs to be fixed up. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
2007-10-11[MIPS] Deforest the function pointer jungle in the time code.Ralf Baechle

2007-10-11[MIPS] Split up war.hRalf Baechle
It was getting a little big, ugly and a primary source for merge conflicts. Also the old method was a bit too forgiving in that the workaround did default to off, so now there is an explicit #error forcing platform maintainers to think if they should enable a workaround for a particular platform.

2007-10-11[MIPS] Sibyte: Replace SB1 cachecode with standard R4000 class cache code.Ralf Baechle
It may not be perfect yet but the SB1 code is badly borken and has horrible performance issues. Downside: This seriously breaks support for pass 1 parts of the BCM1250 where indexed cacheops don't work quite reliable but I seem to be the last one on the planet with a pass 1 part anyway.

2007-10-11[MIPS] Rename CONFIG_BUILD_ELF64 into KBUILD_64BIT_SYM32Franck Bui-Huu
This patch renames it for 3 reasons: - "CONFIG" pattern is used by Kconfig. Now this macro is no more defined by Kconfig but by Kbuild itself make this clear by translating "CONFIG" into "KBUILD". - "ELF32" word is improper because it is irrelevant to ELF format and it makes confusion with CONFIG_BOOT_ELF32. So translate it with SYM32. - Add "64BIT" part to make clear that this macro implies a 64 bits kernel.

2007-10-08mm: set_page_dirty_balance() vs ->page_mkwrite()Peter Zijlstra
All the current page_mkwrite() implementations also set the page dirty. Which results in the set_page_dirty_balance() call to _not_ call balance, because the page is already found dirty. This allows us to dirty a _lot_ of pages without ever hitting balance_dirty_pages(). Not good (tm). Force a balance call if ->page_mkwrite() was successful.

2007-10-07Don't do load-average calculations at even 5-second intervalsLinus Torvalds
It turns out that there are a few other five-second timers in the kernel, and if the timers get in sync, the load-average can get artificially inflated by events that just happen to coincide. So just offset the load average calculation it by a timer tick. Noticed by Anders Boström, for whom the coincidence started triggering on one of his machines with the JBD jiffies rounding code (JBD is one of the subsystems that also end up using a 5-second timer by default).

2007-10-05Remove unnecessary cast in prefetch()Serge Belyshev
It is ok to call prefetch() function with NULL argument, as specifically commented in include/linux/prefetch.h. But in standard C, it is invalid to dereference NULL pointer (see C99 standard 6.5.3.2 paragraph 4 and note #84). prefetch() has a memory reference for its argument. Newer gcc versions (4.3 and above) will use that to conclude that "x" argument is non-null and thus wreaking havok everywhere prefetch() was inlined. Fixed by removing cast and changing asm constraint. [ It seems in theory gcc 4.2 could miscompile this too; although no cases known. In 2.6.24 we should probably switch to __builtin_prefetch() instead, but this is a simpler fix for now. -- AK ] Signed-off-by: Serge Belyshev <belyshev@depni.sinp.msu.ru> Signed-off-by: Andi Kleen <ak@suse.de> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

They contain 64-bit instructions so wouldn't work on 32-bit kernels or 32-bit hardware. Since there are no users, blow them away.
