      sched/wait: Fix the signal handling fix · dfd01f02
      Peter Zijlstra authored
      Jan Stancek reported that I wrecked things for him by fixing things for
      Vladimir :/
      
      His report was due to an UNINTERRUPTIBLE wait getting -EINTR, which
      should not be possible, however my previous patch made this possible by
      unconditionally checking signal_pending().
      
      We cannot use current->state as was done previously, because the
      instruction after the store to that variable it can be changed.  We must
      instead pass the initial state along and use that.
      
      Fixes: 68985633 ("sched/wait: Fix signal handling in bit wait helpers")

      MIPS: fix DMA contiguous allocation · 9530d0fe
      Qais Yousef authored
      Recent changes to how GFP_ATOMIC is defined seems to have broken the
      condition to use mips_alloc_from_contiguous() in
      mips_dma_alloc_coherent().
      
      I couldn't bottom out the exact change but I think it's this commit
      d0164adc ("mm, page_alloc: distinguish between being unable to
      sleep, unwilling to sleep and avoiding waking kswapd").
      
      GFP_ATOMIC has multiple bits set and the check for !(gfp & GFP_ATOMIC)
      isn't enough.
      
      The reason behind this condition is to check whether we can potentially
      do a sleeping memory allocation.  Use gfpflags_allow_blocking() instead
      which should be more robust.

      sh64: fix __NR_fgetxattr · 2d33fa10
      Dmitry V. Levin authored
      According to arch/sh/kernel/syscalls_64.S and common sense, __NR_fgetxattr
      has to be defined to 259, but it doesn't.  Instead, it's defined to 269,
      which is of course used by another syscall, __NR_sched_setaffinity in this
      case.
      
      This bug was found by strace test suite.
