      drm/i915: fix pch pci device enumeration · bcdb72ac
      Imre Deak authored
      pci_get_class(class, from) drops the refcount for 'from', so the
      extra pci_dev_put we do on it will result in a use after free bug
      starting with the WARN below.

      drm/i915: Resolving the memory region conflict for Stolen area · 3617dc96
      Akash Goel authored
      There is a conflict seen when requesting the kernel to reserve
      the physical space used for the stolen area. This is because
      some BIOS are wrapping the stolen area in the root PCI bus, but have
      an off-by-one error. As a workaround we retry the reservation with an
      offset of 1 instead of 0.

      arm64: mm: Add double logical invert to pte accessors · 84fe6826
      Steve Capper authored
      Page table entries on ARM64 are 64 bits, and some pte functions such as
      pte_dirty return a bitwise-and of a flag with the pte value. If the
      flag to be tested resides in the upper 32 bits of the pte, then we run
      into the danger of the result being dropped if downcast.
      
      For example:
      	gather_stats(page, md, pte_dirty(*pte), 1);
      where pte_dirty(*pte) is downcast to an int.
      
      This patch adds a double logical invert to all the pte_ accessors to
      ensure predictable downcasting.

      dm cache: fix truncation bug when mapping I/O to >2TB fast device · e0d849fa
      Heinz Mauelshagen authored
      When remapping a block to the cache's fast device that is larger than
      2TB we must not truncate the destination sector to 32bits.  The 32bit
      temporary result of from_cblock() was being overflowed in
      remap_to_cache() due to the logical left shift.
      
      Use an intermediate 64bit type to store the 32bit from_cblock() result
      to fix the overflow.

      perf tools: Fix strict alias issue for find_first_bit · b39c2a57
      Jiri Olsa authored
      When compiling perf tool code with gcc 4.4.7 I'm getting
      following error:
      
          CC       util/session.o
        cc1: warnings being treated as errors
        util/session.c: In function ‘perf_session_deliver_event’:

        make[1]: *** [util/session.o] Error 1
        make: *** [util/session.o] Error 2
      
      The aliased types here are u64 and unsigned long pointers, which is safe
      for the find_first_bit processing.
      
      This error shows up for me only for gcc 4.4 on 32bit x86, even for
      -Wstrict-aliasing=3, while newer gcc are quiet and scream here for
      -Wstrict-aliasing={2,1}. Looks like newer gcc changed the rules for
      strict alias warnings.
      
      The gcc documentation offers workaround for valid aliasing by using
      __may_alias__ attribute:
      
        http://gcc.gnu.org/onlinedocs/gcc-4.4.0/gcc/Type-Attributes.html
      
      Using this workaround for the find_first_bit function.

      powerpc/powernv: Dump PHB diag-data immediately · 94716604
      Gavin Shan authored
      The PHB diag-data is important to help locating the root cause for
      EEH errors such as frozen PE or fenced PHB. However, the EEH core
      enables IO path by clearing part of HW registers before collecting
      this data causing it to be corrupted.
      
      This patch fixes this by dumping the PHB diag-data immediately when
      frozen/fenced state on PE or PHB is detected for the first time in
      eeh_ops::get_state() or next_error() backend.

      powerpc: Increase stack redzone for 64-bit userspace to 512 bytes · 573ebfa6
      Paul Mackerras authored
      The new ELFv2 little-endian ABI increases the stack redzone -- the
      area below the stack pointer that can be used for storing data --
      from 288 bytes to 512 bytes.  This means that we need to allow more
      space on the user stack when delivering a signal to a 64-bit process.
      
      To make the code a bit clearer, we define new USER_REDZONE_SIZE and
      KERNEL_REDZONE_SIZE symbols in ptrace.h.  For now, we leave the
      kernel redzone size at 288 bytes, since increasing it to 512 bytes
      would increase the size of interrupt stack frames correspondingly.
      
      Gcc currently only makes use of 288 bytes of redzone even when
      compiling for the new little-endian ABI, and the kernel cannot
      currently be compiled with the new ABI anyway.
      
      In the future, hopefully gcc will provide an option to control the
      amount of redzone used, and then we could reduce it even more.
      
      This also changes the code in arch_compat_alloc_user_space() to
      preserve the expanded redzone.  It is not clear why this function would
      ever be used on a 64-bit process, though.

      The branch target should be the func addr, not the addr of func_descr_t.
      So using ppc_function_entry() to generate the right target addr.

      powerpc/crashdump : Fix page frame number check in copy_oldmem_page · f5295bd8
      Laurent Dufour authored
      In copy_oldmem_page, the current check using max_pfn and min_low_pfn to
      decide if the page is backed or not, is not valid when the memory layout is
      not continuous.
      
      This happens when running as a QEMU/KVM guest, where RTAS is mapped higher
      in the memory. In that case max_pfn points to the end of RTAS, and a hole
      between the end of the kdump kernel and RTAS is not backed by PTEs. As a
      consequence, the kdump kernel is crashing in copy_oldmem_page when accessing
      in a direct way the pages in that hole.
      
      This fix relies on the memblock's service memblock_is_region_memory to
      check if the read page is part or not of the directly accessible memory.

      powerpc/le: Ensure that the 'stop-self' RTAS token is handled correctly · 41dd03a9
      Tony Breeds authored
      Currently we're storing a host endian RTAS token in
      rtas_stop_self_args.token.  We then pass that directly to rtas.  This is
      fine on big endian however on little endian the token is not what we
      expect.
      
      This will typically result in hitting:
      	panic("Alas, I survived.\n");
      
      To fix this we always use the stop-self token in host order and always
      convert it to be32 before passing this to rtas.
