Merge branch 'exec_domain_rip_v2' of git://git.kernel.org/pub/scm/linux/kernel/git/rw/misc

2015-04-15T20:53:55+00:00

Pull exec domain removal from Richard Weinberger:
 "This series removes execution domain support from Linux.

  The idea behind exec domains was to support different ABIs.  The
  feature was never complete nor stable.  Let's rip it out and make the
  kernel signal handling code less complicated"

whack-a-mole: no need to set_fs(USER_DS) in {start,flush}_thread()

2015-04-12T02:24:31+00:00

flush_old_exec() has already done that.  Back on 2011 a bunch of
instances like that had been kicked out, but that hadn't taken
care of then-out-of-tree architectures, obviously, and they served
as reinfection vector...

c6x: include: asm: dma-mapping: Add dummy dma_sync_single_range_for_device

2015-03-26T14:47:19+00:00

c6x does not implement get_dma_ops() for dma-mapping-common.h. And in
dma-mapping-common.h, dma_sync_single_range_for_device() may be dummy.
So c6x can just define a dummy function for allmodconfig building.

Some modules may assume "asm/setup.h" already include all headers which
needed by itself. So need let "asm/setup.h" include "linux/types.h", the
related error:
