mm: arch: remove duplicate definitions of MADV_FREE

2016-01-21T01:09:18+00:00

Commits 21f55b018ba5 ("arch/*/include/uapi/asm/mman.h: : let MADV_FREE
have same value for all architectures") and ef58978f1eaa ("mm: define
MADV_FREE for some arches") both defined MADV_FREE, but did not use the
same values.  This results in build errors such as

  ./arch/alpha/include/uapi/asm/mman.h:53:0: error: "MADV_FREE" redefined
  ./arch/alpha/include/uapi/asm/mman.h:50:0: note: this is the location of the previous definition

for the affected architectures.

 "This patchset includes two major fixes which are both scheduled for
  stable:

  First, __ARCH_SI_PREAMBLE_SIZE was defined with a wrong value.
  Second, huge page pte and TLB changes needed protection with a
  spinlock.  Other than that there are just some trivial optimizations
  and cleanups"

arch/*/include/uapi/asm/mman.h: : let MADV_FREE have same value for all architectures

2016-01-16T01:56:32+00:00

For uapi, need try to let all macros have same value, and MADV_FREE is
added into main branch recently, so need redefine MADV_FREE for it.

At present, '8' can be shared with all architectures, so redefine it to
'8'.

mm: define MADV_FREE for some arches

2016-01-16T01:56:32+00:00

Most architectures use asm-generic, but alpha, mips, parisc, xtensa need
their own definitions.

This patch defines MADV_FREE for them so it should fix build break for
their architectures.

Maybe, I should split and feed pieces to arch maintainers but included
here for mmotm convenience.

parisc: Drop parisc-specific NSIGTRAP define

2016-01-12T21:06:15+00:00

NIGTRAP is already defined in asm-generic/siginfo.h, so no need to
define it ourselves.

parisc: Fix __ARCH_SI_PREAMBLE_SIZE

2016-01-12T21:04:09+00:00

On a 64bit kernel build the compiler aligns the _sifields union in the
struct siginfo_t on a 64bit address. The __ARCH_SI_PREAMBLE_SIZE define
compensates for this alignment and thus fixes the wait testcase of the
strace package.

The symptoms of a wrong __ARCH_SI_PREAMBLE_SIZE value is that
_sigchld.si_stime variable is missed to be copied and thus after a
copy_siginfo() will have uninitialized values.

soreuseport: setsockopt SO_ATTACH_REUSEPORT_[CE]BPF

2016-01-05T03:49:59+00:00

Expose socket options for setting a classic or extended BPF program
for use when selecting sockets in an SO_REUSEPORT group.  These options
can be used on the first socket to belong to a group before bind or
on any socket in the group after bind.

This change includes refactoring of the existing sk_filter code to
allow reuse of the existing BPF filter validation checks.

Merge branch 'parisc-4.4-2' of git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux

2015-11-22T20:50:58+00:00

Pull parisc update from Helge Deller:
 "This patchset adds Huge Page and HUGETLBFS support for parisc"

Honestly, the hugepage support should have gone through in the merge
window, and is not really an rc-time fix.  But it only touches
arch/parisc, and I cannot find it in myself to care.  If one of the
three parisc users notices a breakage, I will point at Helge and make
rude farting noises.

* 'parisc-4.4-2' of git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux:
  parisc: Map kernel text and data on huge pages
  parisc: Add Huge Page and HUGETLBFS support
  parisc: Use long branch to do_syscall_trace_exit
  parisc: Increase initial kernel mapping to 32MB on 64bit kernel
  parisc: Initialize the fault vector earlier in the boot process.
  parisc: Add defines for Huge page support
  parisc: Drop unused MADV_xxxK_PAGES flags from asm/mman.h
  parisc: Drop definition of start_thread_som for HP-UX SOM binaries
  parisc: Fix wrong comment regarding first pmd entry flags
