        There are two fixes for data integrity (mostly only showing up on
        module removal), an mvsas crash with expander attached SATA devices
        which goes back to the dawn of the driver but is only just being
        picked up as sas expanders become a standard item in low end server
        hardware, an am53c974 one because the interrupt data isn't fully
        initialised before the line is and a megaraid_sas one because it uses
        smp_processor_id() to select MSI-X queues and that now triggers a

           it as a GEM shared memory handler.  This makes it a lot easier to
           do certain things when you have no GPU but still have to deal with

      smp: don't use 16-bit words for atomic accesses · f4d03bd1
      Linus Torvalds 提交于
      Yes, it should work, but it's a bad idea.  Not only did ARM64 not have
      the 16-bit access code (there's a separate patch to add it), it's just
      not a good atomic type.  Some architectures fundamentally don't do
      atomic accesses in them (alpha), and it's not like it saves any space
      here anyway because of structure packing issues.
      
      We normally should aim for flags to be "unsigned int" or "unsigned
      long".  And if space is at a premium, use a single byte (although that
      causes problems on alpha again).  There might be very special cases
      where a 16-byte entity is really wanted, but this is not one of them.

      Merge branch 'x86-pmem-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip · 34a984f7
      Linus Torvalds 提交于
      Pull PMEM driver from Ingo Molnar:
       "This is the initial support for the pmem block device driver:
        persistent non-volatile memory space mapped into the system's physical
        memory space as large physical memory regions.
      
        The driver is based on Intel code, written by Ross Zwisler, with fixes
        by Boaz Harrosh, integrated with x86 e820 memory resource management
        and tidied up by Christoph Hellwig.
      
        Note that there were two other separate pmem driver submissions to
        lkml: but apparently all parties (Ross Zwisler, Boaz Harrosh) are
        reasonably happy with this initial version.
      
        This version enables minimal support that enables persistent memory
        devices out in the wild to work as block devices, identified through a
        magic (non-standard) e820 flag and auto-discovered if
        CONFIG_X86_PMEM_LEGACY=y, or added explicitly through manipulating the
        memory maps via the "memmap=..." boot option with the new, special '!'
        modifier character.
      
        Limitations: this is a regular block device, and since the pmem areas
        are not struct page backed, they are invisible to the rest of the
        system (other than the block IO device), so direct IO to/from pmem
        areas, direct mmap() or XIP is not possible yet.  The page cache will
        also shadow and double buffer pmem contents, etc.
      
        Initial support is for x86"
