      crypto: vmac - Make VMAC work when blocks aren't aligned · ba1ee070
      Salman Qazi 提交于
      VMAC implementation, as it is, does not work with blocks that
      are not multiples of 128-bytes.  Furthermore, this is a problem
      when using the implementation on scatterlists, even
      when the complete plain text is 128-byte multiple, as the pieces
      that get passed to vmac_update can be pretty much any size.
      
      I also added test cases for unaligned blocks.

      crypto: crc32c - Optimize CRC32C calculation with PCLMULQDQ instruction · 6a8ce1ef
      Tim Chen 提交于
      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.

      x86, boot: Explicitly include autoconf.h for hostprogs · b6eea87f
      Matt Fleming 提交于
      The hostprogs need access to the CONFIG_* symbols found in
      include/generated/autoconf.h.  But commit abbf1590 ("UAPI: Partition
      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.

      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.

      ARM: config: sort select statements alphanumerically · b1b3f49c
      Russell King 提交于
      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.
