      drm/vmwgfx: Fix execbuf locking issues · 3e04e2fe
      Thomas Hellstrom authored
      This addresses two issues that cause problems with viewperf maya-03 in
      situation with memory pressure.
      
      The first issue causes attempts to unreserve buffers if batched
      reservation fails due to, for example, a signal pending. While previously
      the ttm_eu api was resistant against this type of error, it is no longer
      and the lockdep code will complain about attempting to unreserve buffers
      that are not reserved. The issue is resolved by avoid calling
      ttm_eu_backoff_reservation in the buffer reserve error path.
      
      The second issue is that the binding_mutex may be held when user-space
      fence objects are created and hence during memory reclaims. This may cause
      recursive attempts to grab the binding mutex. The issue is resolved by not
      holding the binding mutex across fence creation and submission.

      Revert x86 sigcontext cleanups · ed596cde
      Linus Torvalds authored
      This reverts commits 9a036b93 ("x86/signal/64: Remove 'fs' and 'gs'
      from sigcontext") and c6f20629 ("x86/signal/64: Fix SS handling for
      signals delivered to 64-bit programs").
      
      They were cleanups, but they break dosemu by changing the signal return
      behavior (and removing 'fs' and 'gs' from the sigcontext struct - while
      not actually changing any behavior - causes build problems).

        de3910eb ("edac: change the mem allocation scheme to
      		 make Documentation/kobject.txt happy")
      
      changed the memory allocation for the csrows member. But ppc4xx_edac was
      forgotten in the patch. Fix it.
