      s390/fpu: signals vs. floating point control register · 1b17cb79
      Martin Schwidefsky authored
      git commit 904818e2
      "s390/kernel: introduce fpu-internal.h with fpu helper functions"
      introduced the fpregs_store / fp_regs_load helper. These function
      fail to save and restore the floating pointer control registers.
      
      The effect is that the FPC is not correctly handled on signal
      delivery and signal return.

      s390/compat: correct restore of high gprs on signal return · 342300cc
      Martin Schwidefsky authored
      git commit 80703617
      "s390: add support for vector extension"
      broke 31-bit compat processes in regard to signal handling.
      
      The restore_sigregs_ext32() function is used to restore the additional
      elements from the user space signal frame. Among the additional elements
      are the upper registers halves for 64-bit register support for 31-bit
      processes. The copy_from_user that is used to retrieve the high-gprs
      array from the user stack uses an incorrect length, 8 bytes instead of
      64 bytes. This causes incorrect upper register halves to get loaded.

      kernel/resource.c: fix muxed resource handling in __request_region() · 59ceeaaf
      Simon Guinot authored
      In __request_region, if a conflict with a BUSY and MUXED resource is
      detected, then the caller goes to sleep and waits for the resource to be
      released.  A pointer on the conflicting resource is kept.  At wake-up
      this pointer is used as a parent to retry to request the region.
      
      A first problem is that this pointer might well be invalid (if for
      example the conflicting resource have already been freed).  Another
      problem is that the next call to __request_region() fails to detect a
      remaining conflict.  The previously conflicting resource is passed as a
      parameter and __request_region() will look for a conflict among the
      children of this resource and not at the resource itself.  It is likely
      to succeed anyway, even if there is still a conflict.
      
      Instead, the parent of the conflicting resource should be passed to
      __request_region().
      
      As a fix, this patch doesn't update the parent resource pointer in the
      case we have to wait for a muxed region right after.

       "Here are some more arm64 fixes for 4.5.  This has mostly come from
        Yang Shi, who saw some issues under -rt that also affect mainline.
        The rest of it is pretty small, but still worth having.
      
        We've got an old issue outstanding with valid_user_regs which will
        likely wait until 4.6 (since it would really benefit from some time in
        -next) and another issue with kasan and idle which should be fixed
        next week.
      
        Apart from that, pretty quiet here (and still no sign of the THP issue
        reported on s390...)
      
        Summary:
      
         - Allow EFI stub to use strnlen(), which is required by recent libfdt
      
         - Avoid smp_processor_id() in preempt context during unwinding
      
         - Avoid false Kasan warnings during unwinding
      
         - Ensure early devices are picked up by the IOMMU DMA ops
