kbuild: Fix removal of the debian/ directory

2015-01-27T16:29:45+00:00

commit a16c5f99a28c9945165c46da27fff8e6f26f8736 upstream.

scripts/Makefile.clean treats absolute path specially, but
$(objtree)/debian is no longer an absolute path since 7e1c0477 (kbuild:
Use relative path for $(objtree). Work around this by checking if the
path starts with $(objtree)/.

bugon.cocci: fix Options at the macro

2015-01-27T16:29:39+00:00

commit 7426977c8efeaedf0a7ca00e1c1a5f52ef6b950f upstream.

The comma after --no-includes makes coccinelle to not run the script:

/usr/bin/spatch -D report --very-quiet --no-show-diff --cocci-file ./scripts/coccinelle/misc/bugon.cocci --no-includes, --include-headers --patch . --dir drivers/media/platform/coda/ -I ./arch/x86/include -I arch/x86/include/generated -I include -I ./arch/x86/include/uapi -I arch/x86/include/generated/uapi -I ./include/uapi -I include/generated/uapi -I ./include/linux/kconfig.h
Usage: spatch.opt --sp-file   [-o ] [--iso-file ] [options]
Options are:
  --sp-file                     the semantic patch file
  -o                            the output file
  --in-place                   do the modification on the file directly
  --backup-suffix              suffix to use when making a backup for inplace

scripts/kernel-doc: don't eat struct members with __aligned

2015-01-16T14:59:54+00:00

commit 7b990789a4c3420fa57596b368733158e432d444 upstream.

The change from \d+ to .+ inside __aligned() means that the following
structure:

  struct test {
        u8 a __aligned(2);
        u8 b __aligned(2);
  };

essentially gets modified to

  struct test {
        u8 a;
  };

for purposes of kernel-doc, thus dropping a struct member, which in
turns causes warnings and invalid kernel-doc generation.

Fix this by replacing the catch-all (".") with anything that's not a
semicolon ("[^;]").

Fixes: 9dc30918b23f ("scripts/kernel-doc: handle struct member __aligned without numbers")

Pull s390 updates from Martin Schwidefsky:
 "This patch set contains the main portion of the changes for 3.18 in
  regard to the s390 architecture.  It is a bit bigger than usual,
  mainly because of a new driver and the vector extension patches.

  The interesting bits are:
   - Quite a bit of work on the tracing front.  Uprobes is enabled and
     the ftrace code is reworked to get some of the lost performance
     back if CONFIG_FTRACE is enabled.
   - To improve boot time with CONFIG_DEBIG_PAGEALLOC, support for the
     IPTE range facility is added.
   - The rwlock code is re-factored to improve writer fairness and to be
     able to use the interlocked-access instructions.
   - The kernel part for the support of the vector extension is added.
   - The device driver to access the CD/DVD on the HMC is added, this
     will hopefully come in handy to improve the installation process.
   - Add support for control-unit initiated reconfiguration.
   - The crypto device driver is enhanced to enable the additional AP
     domains and to allow the new crypto hardware to be used.
   - Bug fixes"
