| * MIPS: O32: Provide definition of registers ta0 .. ta3.Ralf Baechle2011-10-241-0/+6
| | | | | | | | | | | | Later IRIX versions provide them in <sys/regdef.h> and gas also accepts $ta0 .. $ta3 since binutils 2.18 so Linux should do the same for source compatibility.

| | | | | | | | | | | | | | | | | | | | | | | | | | Now that no driver any longer depends on the CONFIG_SOC_AU1??? symbols, it's time to get rid of them: Move some of the platform devices to the boards which can use them, Rename a few (unused) constants in the header, Replace them with MIPS_ALCHEMY in the various Kconfig files. Finally delete them altogether from the Alchemy Kconfig file.

| * Revert "MIPS: LD/SD o32 macro GAS fix update"Ralf Baechle2011-10-201-10/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This reverts commit 97475f8b42e83be2966aa2d70ab9c98477701c53 (lmo) / 82b89152f00f7ad17844d5614d5011e8d7944ac9 (kernel.org) [MIPS: LD/SD o32 macro GAS fix update]. Turns out this patch is producing many build errors with gcc 4.2. Based on further testing with a test case extracted from the build errors found further build errors and suboptimal generation even in violation of the "R" constraint. To make matters worse, the binutils changes also don't work quite as intended so revert this patch for now.
| * MIPS: SNI: Fix conflicting wrapper symbols for headers.Ralf Baechle2011-10-202-6/+6
| | | | | | | | | | | | | | | | | | | | If Open Firmware / Device Tree support is enabled on a SNI RM kernel both <asm/mipsprom.h> and <asm/prom.h> will be included into some .c files. Since both headers use the same wrapper symbol only the inclusion of the first file will have an effect but the 2nd file will be ignored resulting in a build error.

| | | | | | | | | | | | | | | | | | | | | | | | Until now flush_kernel_vmap_range() and invalidate_kernel_vmap_range() did not exist on MIPS resulting in heavy cache corruption on XFS filesystems. Left for the post-3.0 time: optimization and make this work with highmem, too. Since the combination of highmem + cache aliases atm doesn't work this isn't a regression.

| * | compat: sync compat_stats with statfs.Eric W. Biederman2011-10-281-1/+2
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This was found by inspection while tracking a similar bug in compat_statfs64, that has been fixed in mainline since decemeber. - This fixes a bug where not all of the f_spare fields were cleared on mips and s390. - Add the f_flags field to struct compat_statfs - Copy f_flags to userspace in case someone cares. - Use __clear_user to copy the f_spare field to userspace to ensure that all of the elements of f_spare are cleared. On some architectures f_spare is has 5 ints and on some architectures f_spare only has 4 ints. Which makes the previous technique of clearing each int individually broken. I don't expect anyone actually uses the old statfs system call anymore but if they do let them benefit from having the compat and the native version working the same. Signed-off-by: Eric W.

Before adding support for bcma it should be possible to build bcm47xx without the need of ssb.

There are already three targets that need to override FIXADDR_TOP, and others exist. This will be a cleaner approach than adding lots of ifdefs in fixmap.h .

| * MIPS: topdown mmap supportJian Peng2011-07-251-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch introduced topdown mmap support in user process address space allocation policy. Recently, we ran some large applications that use mmap heavily and lead to OOM due to inflexible mmap allocation policy on MIPS32. Since most other major archs supported it for years, it is reasonable to follow the trend and reduce the pain of porting applications. Due to cache aliasing concern, arch_get_unmapped_area_topdown() and other helper functions are implemented in arch/mips/kernel/syscall.c.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since 6be63bbbdab66b9185dc6f67c8b1bacb6f37f946 (lmo) rsp. af3a1f6f4813907e143f87030cde67a9971db533 (kernel.org) the Malta code does no longer probe for presence of GCMP if CMP is not configured. This means that the variable gcmp_present well be left at its default value of -1 which normally is meant to indicate that GCMP has not yet been mmapped. This non-zero value is now interpreted as GCMP being present resulting in a write attempt to a GCMP register resulting in a crash.
