ACPICA commit 918a840d27d620942e0ecb69de320bb71ea86c5a

ElseIf is a macro that resolves to an Else..If in the AML byte code.
This support merges an Else followed immediately by an If to an
ASL ElseIf operator. Simplifies decoded ASL, especially for large
Switch statements.

This patch only applies to iasl, and is no-op for Linux kernel.

ACPICA commit 80e60d72959bb51c5d08c8500d978607a42ed81d

BIOS developers may accidently put the quotes around the name strings,
which converts the object references in the packages indicated by the name
strings into the data objects (strings). Such kind of error has been seen
in _DEP control methods on some platforms. This patch implements a

This reverts commit 8e7a8753827660c3dd1f571f3185610402b756f0.

The _SUB method was found to be problematic for this interface
because some implementations use control methods. Therefore,
it is being removed.

Operations cannot be used because this interface is called
during the device discovery scan and the region handlers are
not fully installed at that time.

Pull ftrace/recordmcount fix from Steven Rostedt:
 "Russell King was reporting lots of warnings when he compiled his
  kernel with ftrace enabled.  With some investigation it was discovered
  that it was his compile setup.  He was using ccache with hard links,
  which allowed recordmcount to process the same .o twice.  When this
  happens, recordmcount will detect that it was already done and give a
  warning about it.

  Russell fixed this by having recordmcount detect that the object file
  has more than one hard link, and if it does, it unlinks the object
  file after it maps it and processes then.  This appears to fix the
  issue.

  As you did not like the fact that recordmcount modified the file in
  place and thought that it should do the modifications in memory and
  then write it out to disk and move it over the old file to prevent
  other more subtle issues like the one above, a second patch is added
  on top of Russell's to do just that.  Luckily the original code had
  write and lseek wrappers that I was able to modify to not do inplace
  writes, but simply keep track of the changes made in memory.  When a
  write is made, a "update" flag is set, and at the end of processing,
  if the update is set, then it writes the file with changes out to a
  new file, and then renames it over the original one.

  The file descriptor is still passed to the write and lseek wrappers
  because removing that would cause the change to be more intrusive.
  That can be removed in a follow up cleanup patch that can wait till
  the next merge window"
