        vmcoreinfo PT_NOTE merged this time around which we'd like to get
        sorted before it becomes ABI.

      asm-generic: io: Fix ioport_map() for !CONFIG_GENERIC_IOMAP && CONFIG_INDIRECT_PIO · 500dd232
      Andrew Murray authored
      The !CONFIG_GENERIC_IOMAP version of ioport_map uses MMIO_UPPER_LIMIT to
      prevent users from making I/O accesses outside the expected I/O range -
      however it erroneously treats MMIO_UPPER_LIMIT as a mask which is
      contradictory to its other users.
      
      The introduction of CONFIG_INDIRECT_PIO, which subtracts an arbitrary
      amount from IO_SPACE_LIMIT to form MMIO_UPPER_LIMIT, results in ioport_map
      mangling the given port rather than capping it.
      
      We address this by aligning more closely with the CONFIG_GENERIC_IOMAP
      implementation of ioport_map by using the comparison operator and
      returning NULL where the port exceeds MMIO_UPPER_LIMIT. Though note that
      we preserve the existing behavior of masking with IO_SPACE_LIMIT such that
      we don't break existing buggy drivers that somehow rely on this masking.

      mm: get rid of vmacache_flush_all() entirely · 7a9cdebd
      Linus Torvalds authored
      Jann Horn points out that the vmacache_flush_all() function is not only
      potentially expensive, it's buggy too.  It also happens to be entirely
      unnecessary, because the sequence number overflow case can be avoided by
      simply making the sequence number be 64-bit.  That doesn't even grow the
      data structures in question, because the other adjacent fields are
      already 64-bit.
      
      So simplify the whole thing by just making the sequence number overflow
      case go away entirely, which gets rid of all the complications and makes
      the code faster too.  Win-win.

      pstore: Fix incorrect persistent ram buffer mapping · 831b624d
      Bin Yang authored
      persistent_ram_vmap() returns the page start vaddr.
      persistent_ram_iomap() supports non-page-aligned mapping.
      
      persistent_ram_buffer_map() always adds offset-in-page to the vaddr
      returned from these two functions, which causes incorrect mapping of
      non-page-aligned persistent ram buffer.
      
      By default ftrace_size is 4096 and max_ftrace_cnt is nr_cpu_ids. Without
      this patch, the zone_sz in ramoops_init_przs() is 4096/nr_cpu_ids which
      might not be page aligned. If the offset-in-page > 2048, the vaddr will be
      in next page. If the next page is not mapped, it will cause kernel panic:

      null_blk: fix zoned support for non-rq based operation · b228ba1c
      Jens Axboe authored
      The supported added for zones in null_blk seem to assume that only rq
      based operation is possible. But this depends on the queue_mode setting,
      if this is set to 0, then cmd->bio is what we need to be operating on.
      Right now any attempt to load null_blk with queue_mode=0 will
      insta-crash, since cmd->rq is NULL and null_handle_cmd() assumes it to
      always be set.
      
      Make the zoned code deal with bio's instead, or pass in the
      appropriate sector/nr_sectors instead.
