sh: migrate to arch/sh/include/

2008-07-28T23:09:44+00:00

This follows the sparc changes a439fe51a1f8eb087c22dd24d69cebae4a3addac. Most of the moving about was done with Sam's directions at: http://marc.info/?l=linux-sh&m=121724823706062&w=2 with subsequent hacking and fixups entirely my fault. Signed-off-by: Sam Ravnborg Signed-off-by: Paul Mundt

sh: Add support for 16kB PAGE_SIZE.

2008-07-28T09:10:29+00:00

16kB is a useful size on nommu, while 64kB still tends to be too big to be useful. Newer MMUs are likely to support this as well, so plug it in in anticipation of those, too. Signed-off-by: Paul Mundt

clean up duplicated alloc/free_thread_info

2008-07-25T17:53:28+00:00

We duplicate alloc/free_thread_info defines on many platforms (the majority uses __get_free_pages/free_pages). This patch defines common defines and removes these duplicated defines. __HAVE_ARCH_THREAD_INFO_ALLOCATOR is introduced for platforms that do something different.

remove unused TIF_NOTIFY_RESUME flag

2007-07-31T22:39:38+00:00

Remove unused TIF_NOTIFY_RESUME flag for all processor architectures. The flag was not used excecpt on IA-64 where the patch replaces it with TIF_PERFMON_WORK. Signed-off-by: stephane eranian Cc: Cc: "Luck, Tony" Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

sh: Clear UBC when not in use.

2007-03-05T05:13:25+00:00

This takes care of tearing down the UBC so it's not inadvertently left configured at the next context switch time. Failure to do this results in spurious SIGTRAPs in certain debug sequences. Signed-off-by: Stuart Menefy Signed-off-by: Paul Mundt

sh: More tidying for large base pages.

2007-02-13T01:54:44+00:00

There were a few more things that needed fixing up, namely THREAD_SIZE and the TLB miss handler where certain PTRS_PER_PGD == PTRS_PER_PTE assumptions were being made. Signed-off-by: Paul Mundt

[PATCH] PM: Fix SMP races in the freezer

2006-12-13T17:05:49+00:00

Currently, to tell a task that it should go to the refrigerator, we set the PF_FREEZE flag for it and send a fake signal to it. Unfortunately there are two SMP-related problems with this approach. First, a task running on another CPU may be updating its flags while the freezer attempts to set PF_FREEZE for it and this may leave the task's flags in an inconsistent state. Second, there is a potential race between freeze_process() and refrigerator() in which freeze_process() running on one CPU is reading a task's PF_FREEZE flag while refrigerator() running on another CPU has just set PF_FROZEN for the same task and attempts to reset PF_FREEZE for it. If the refrigerator wins the race, freeze_process() will state that PF_FREEZE hasn't been set for the task and will set it unnecessarily, so the task will go to the refrigerator once again after it's been thawed. To solve first of these problems we need to stop using PF_FREEZE to tell tasks that they should go to the refrigerator. Instead, we can introduce a special TIF_*** flag and use it for this purpose, since it is allowed to change the other tasks' TIF_*** flags and there are special calls for it. To avoid the freeze_process()-refrigerator() race we can make freeze_process() to always check the task's PF_FROZEN flag after it's read its "freeze" flag. We should also make sure that refrigerator() will always reset the task's "freeze" flag after it's set PF_FROZEN for it. Signed-off-by: Rafael J.
