2012-03-27Merge branch 'fixes-non-critical' into next/drivers2Olof Johansson
fixes-non-critical has already been merged upstream, and there are a handful of annoying context conflicts that it makes sense to resolve before sending up. Part of this is because there was parallel development going on between more urgent fixes and general driver fixups, it should settle down once the lpc32xx platform reaches a more steady state. Conflicts: arch/arm/mach-lpc32xx/clock.c arch/arm/mach-lpc32xx/common.h Signed-off-by: Olof Johansson <olof@lixom.net>

The one fix didn't make the cut for 3.3, so we're putting it into v3.4. Tony tells me "There are more patches needed to make multiple smsc91x instances work, but we need to hear from people with such boards first. Then those can be tagged for stable.", so we don't mark this patch stable yet. Signed-off-by: Arnd Bergmann <arnd@arndb.de>

2012-03-13iomux-mx25.h slew rate adjusted for LCD __LD pinsMehnert
For some reason (sadly i don't identifying the patch right now) two LCD data lines configured PAD_CTL_SRE_SLOW (wrong slew rate) since Kernel 3.1. MX25_PAD_GPIO_E__LD16 and MX25_PAD_GPIO_F__LD17 This results in an fauly behaviour and strange color effects. To ensure that all LCD data pins configured with the proper slew rate, this patch changes to IOMUX define of all LCD __LDxx pins to PAD_CTL_SRE_FAST. This problem may affect other mx25 platforms like mx25pdk. Sadly i can't test it. Of course this problem shouldn't occur when you done your LCD muxing correctly in the bootloader.

2012-03-09aio: fix the "too late munmap()" raceAl Viro
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().

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...

2012-03-09memcg: revert fix to mapcount check for this releaseHugh Dickins
Respectfully revert commit e6ca7b89dc76 "memcg: fix mapcount check in move charge code for anonymous page" for the 3.3 release, so that it behaves exactly like releases 2.6.35 through 3.2 in this respect. Horiguchi-san's commit is correct in itself, 1 makes much more sense than 2 in that check; but it does not go far enough - swapcount should be considered too - if we really want such a check at all. We appear to have reached agreement now, and expect that 3.4 will remove the mapcount check, but had better not make 3.3 different.

2012-03-09x86: Derandom delay_tsc for 64 bitThomas Gleixner
Commit f0fbf0abc093 ("x86: integrate delay functions") converted delay_tsc() into a random delay generator for 64 bit. The reason is that it merged the mostly identical versions of delay_32.c and delay_64.c. Though the subtle difference of the result was: static void delay_tsc(unsigned long loops) { - unsigned bclock, now; + unsigned long bclock, now; Now the function uses rdtscl() which returns the lower 32bit of the TSC. On 32bit that's not problematic as unsigned long is 32bit. On 64 bit this fails when the lower 32bit are close to wrap around when bclock is read, because the following check if ((now - bclock) >= loops) break; evaluated to true on 64bit for e.g. bclock = 0xffffffff and now = 0 because the unsigned long (now - bclock) of these values results in 0xffffffff00000001 which is definitely larger than the loops value. That explains Tvortkos observation: "Because I am seeing udelay(500) (_occasionally_) being short, and that by delaying for some duration between 0us (yep) and 491us." Make those variables explicitely u32 again, so this works for both 32 and 64 bit.
