      random: prime last_data value per fips requirements · ec8f02da
      Jarod Wilson authored
      
      
      The value stored in last_data must be primed for FIPS 140-2 purposes. Upon
      first use, either on system startup or after an RNDCLEARPOOL ioctl, we
      need to take an initial random sample, store it internally in last_data,
      then pass along the value after that to the requester, so that consistency
      checks aren't being run against stale and possibly known data.

      random: make it possible to enable debugging without rebuild · be5b779a
      Jiri Kosina authored
      
      
      The module parameter that turns debugging mode (which basically means
      printing a few extra lines during runtime) is in '#if 0' block. Forcing
      everyone who would like to see how entropy is behaving on his system to
      rebuild seems to be a little bit too harsh.
      
      If we were concerned about speed, we could potentially turn 'debug' into a
      static key, but I don't think it's necessary.
      
      Drop the '#if 0' block to allow using the 'debug' parameter without rebuilding.

      x86, boot: Explicitly include autoconf.h for hostprogs · b6eea87f
      Matt Fleming authored
      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 authored
      
      
      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,
      Linus and Sekhar.)
