2012-03-12ARM: mach-shmobile: default to no earlytimerMagnus Damm1-1/+0
Now when all SoCs and boards are converted to use shmobile_earlytimer_init(), change the default behavior of shmobile_timer.init() from using early timer to do nothing which is suitable for upcoming DT support.

2012-03-12ARM: mach-shmobile: r8a7779 and Marzen timer reworkMagnus Damm2-13/+11
Move the SoC specific timer code from Marzen board code to r8a7779 setup code. This makes is possible to share the SoC specific timer code across boards and it also removes the need for a board specific timer structure.

2012-03-09aio: fix the "too late munmap()" raceAl Viro1-8/+6
Current code has put_ioctx() called asynchronously from aio_fput_routine(); that's done *after* we have killed the request that used to pin ioctx, so there's nothing to stop io_destroy() waiting in wait_for_all_aios() from progressing. As the result, we can end up with async call of put_ioctx() being the last one and possibly happening during exit_mmap() or elf_core_dump(), neither of which expects stray munmap() being done to them... We do need to prevent _freeing_ ioctx until aio_fput_routine() is done with that, but that's all we care about - neither io_destroy() nor exit_aio() will progress past wait_for_all_aios() until aio_fput_routine() does really_put_req(), so the ioctx teardown won't be done until then and we don't care about the contents of ioctx past that point. Since actual freeing of these suckers is RCU-delayed, we don't need to bump ioctx refcount when request goes into list for async removal. All we need is rcu_read_lock held just over the ->ctx_lock-protected area in aio_fput_routine().

2012-03-09aio: fix io_setup/io_destroy raceAl Viro1-4/+4
Have ioctx_alloc() return an extra reference, so that caller would drop it on success and not bother with re-grabbing it on failure exit. The current code is obviously broken - io_destroy() from another thread that managed to guess the address io_setup() would've returned would free ioctx right under us; gets especially interesting if aio_context_t * we pass to io_setup() points to PROT_READ mapping, so put_user() fails and we end up doing io_destroy() on kioctx another thread has just got freed...
