This patch adds a test case in tcrypt to perform speed test for
crc32c checksum calculation.
Signed-off-by: NTim Chen <tim.c.chen@linux.intel.com>
Signed-off-by: NHerbert Xu <herbert@gondor.apana.org.au>

This patch adds the crc_pcl function that calculates CRC32C checksum using the
PCLMULQDQ instruction on processors that support this feature. This will
provide speedup over using CRC32 instruction only.
The usage of PCLMULQDQ necessitate the invocation of kernel_fpu_begin and
kernel_fpu_end and incur some overhead.  So the new crc_pcl function is only
invoked for buffer size of 512 bytes or more.  Larger sized
buffers will expect to see greater speedup.  This feature is best used coupled
with eager_fpu which reduces the kernel_fpu_begin/end overhead.  For
buffer size of 1K the speedup is around 1.6x and for buffer size greater than
4K, the speedup is around 3x compared to original implementation in crc32c-intel
module. Test was performed on Sandy Bridge based platform with constant frequency
set for cpu.

the header include path sets and add uapi/ header directories") replaced
$(LINUXINCLUDE) with $(USERINCLUDE) which doesn't contain the necessary
include paths.

This has the undesirable effect of breaking the EFI boot stub because
the #ifdef CONFIG_EFI_STUB code in arch/x86/boot/tools/build.c is
never compiled.

It should also be noted that because $(USERINCLUDE) isn't exported by
the top-level Makefile it's actually empty in arch/x86/boot/Makefile.

  ARM part of David Howells UAPI changes, and a fix to the ordering of
  'select' statements in ARM Kconfig files (see the appropriate commit
  for why this happened - thanks to Andrew Morton for pointing out the
  problem.)

  I've left this as long as I dare for this window to avoid conflicts,
  and I regenerated the config patch yesterday, posting it to our
  mailing list for review and testing.  I have several acks which
  include successful test reports for it.

  However, today I notice we've got new conflicts with previously unseen
  code...  though that conflict should be trivial (it's my changes vs a
  one liner.)"

Pull UAPI disintegration for include/linux/{,byteorder/}*.h from David Howells:
 "The patches contained herein do the following:

 (1) Remove kernel-only stuff in linux/ppp-comp.h from the UAPI.  I checked
     this with Paul Mackerras before I created the patch and he suggested some
     extra bits to unexport.

 (2) Remove linux/blk_types.h entirely from the UAPI as none of it is userspace
     applicable, and remove from the UAPI that part of linux/fs.h that was the
     reason for linux/blk_types.h being exported in the first place.  I
     discussed this with Jens Axboe before creating the patch.

 (3) The big patch of the series to disintegrate include/linux/*.h as a unit.
     This could be split up, though there would be collisions in moving stuff
     between the two Kbuild files when the parts are merged as that file is
     sorted alphabetically rather than being grouped by subsystem.

     Of this set of headers, 17 files have changed in the UAPI exported region
     since the 4th and only 8 since the 9th so there isn't much change in this
     area - as one might expect.

     It should be pretty obvious and straightforward if it does come to fixing
     up: stuff in __KERNEL__ guards stays where it is and stuff outside moves
     to the same file in the include/uapi/linux/ directory.

     If a new file appears then things get a bit more complicated as the
     "headers +=" line has to move to include/uapi/linux/Kbuild.  Only one new
     file has appeared since the 9th and I judge this type of event relatively
     unlikely.

As suggested by Andrew Morton:

  This is a pet peeve of mine.  Any time there's a long list of items
  (header file inclusions, kconfig entries, array initalisers, etc) and
  someone wants to add a new item, they *always* go and stick it at the
  end of the list.

  Guys, don't do this.  Either put the new item into a randomly-chosen
  position or, probably better, alphanumerically sort the list.

lets sort all our select statements alphanumerically.  This commit was
created by the following perl:

while (<>) {
	while (/\\\s*$/) {
		$_ .= <>;
	}
	undef %selects if /^\s*config\s+/;
	if (/^\s+select\s+(\w+).*/) {
		if (defined($selects{$1})) {
			if ($selects{$1} eq $_) {
				print STDERR "Warning: removing duplicated $1 entry\n";
			} else {
				print STDERR "Error: $1 differently selected\n".
					"\tOld: $selects{$1}\n".
					"\tNew: $_\n";
				exit 1;
			}
		}
		$selects{$1} = $_;
		next;
	}
	if (%selects and (/^\s*$/ or /^\s+help/ or /^\s+---help---/ or
			  /^endif/ or /^endchoice/)) {
		foreach $k (sort (keys %selects)) {
			print "$selects{$k}";
		}
		undef %selects;
	}
	print;
}
if (%selects) {
	foreach $k (sort (keys %selects)) {
		print "$selects{$k}";
	}
}

It found two duplicates:

Warning: removing duplicated S5P_SETUP_MIPIPHY entry
Warning: removing duplicated HARDIRQS_SW_RESEND entry

and they are identical duplicates, hence the shrinkage in the diffstat
of two lines.

We have four testers reporting success of this change (Tony, Stephen,
