2007-10-11[MIPS] Avoid indexed cacheops.Ralf Baechle
On MP configurations it's highly dubious what this code will actually affect since blasting away cachelines may or may not do the right thing wrt. cache coherency. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
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.

2007-09-11[MIPS] Fix aliasing bug in copy_user_highpage.Ralf Baechle
Copy_user_highpage was written assuming it was only being called for breaking COW pages in which case the source page isn't cached as in marked cachable under it kernel virtual address. If it is called anyway the aliasing avoidance strategy implemented by kmap_coherent will fail. Avoid the use of kmap_coherent for pages marked dirty and to avoid another instance of this sort of bug, place a BUG_ON in kmap_coherent. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

2007-07-19mm: fault feedback #2Nick Piggin
This patch completes Linus's wish that the fault return codes be made into bit flags, which I agree makes everything nicer. This requires requires all handle_mm_fault callers to be modified (possibly the modifications should go further and do things like fault accounting in handle_mm_fault -- however that would be for another patch).

2007-05-21Detach sched.h from mm.hAlexey Dobriyan
First thing mm.h does is including sched.h solely for can_do_mlock() inline function which has "current" dereference inside. By dealing with can_do_mlock() mm.h can be detached from sched.h which is good. See below, why. This patch a) removes unconditional inclusion of sched.h from mm.h b) makes can_do_mlock() normal function in mm/mlock.c c) exports can_do_mlock() to not break compilation d) adds sched.h inclusions back to files that were getting it indirectly. e) adds less bloated headers to some files (asm/signal.h, jiffies.h) that were getting them indirectly Net result is: a) mm.h users would get less code to open, read, preprocess, parse, ... if they don't need sched.h b) sched.h stops being dependency for significant number of files: on x86_64 allmodconfig touching sched.h results in recompile of 4083 files, after patch it's only 3744 (-8.3%).

2007-02-11[PATCH] extend the set of "__attribute__" shortcut macrosRobert P. J. Day
Extend the set of "__attribute__" shortcut macros, and remove identical (and now superfluous) definitions from a couple of source files. based on a page at robert love's blog: http://rlove.org/log/2005102601 extend the set of shortcut macros defined in compiler-gcc.h with the following: #define __packed __attribute__((packed)) #define __weak __attribute__((weak)) #define __naked __attribute__((naked)) #define __noreturn __attribute__((noreturn)) #define __pure __attribute__((pure)) #define __aligned(x) __attribute__((aligned(x))) #define __printf(a,b) __attribute__((format(printf,a,b))) Once these are in place, it's up to subsystem maintainers to decide if they want to take advantage of them. there is already a strong precedent for using shortcuts like this in the source tree. The ones that might give people pause are "__aligned" and "__printf", but shortcuts for both of those are already in use, and in some ways very confusingly. note the two very different definitions for a macro named "ALIGNED": drivers/net/sgiseeq.c:#define ALIGNED(x) ((((unsigned long)(x)) + 0xf) & ~(0xf)) drivers/scsi/ultrastor.c:#define ALIGNED(x) __attribute__((aligned(x))) also: include/acpi/platform/acgcc.h: #define ACPI_PRINTF_LIKE(c) __attribute__ ((__format__ (__printf__, c, c+1))) Given the precedent, then, it seems logical to at least standardize on a consistent set of these macros.
