parisc: Drop alloc_hugepages and free_hugepages syscalls

2016-03-23T14:42:18+00:00

The system calls alloc_hugepages() and free_hugepages() were introduced
in Linux 2.5.36 and removed again in 2.5.54. They were never implemented
on parisc, so let's drop them now.

Several cases of overlapping changes, as well as one instance
(vxlan) of a bug fix in 'net' overlapping with code movement
in 'net-next'.

net: Facility to report route quality of connected sockets

2016-02-26T03:01:22+00:00

This patch add the SO_CNX_ADVICE socket option (setsockopt only). The
purpose is to allow an application to give feedback to the kernel about
the quality of the network path for a connected socket. The value
argument indicates the type of quality report. For this initial patch
the only supported advice is a value of 1 which indicates "bad path,
please reroute"-- the action taken by the kernel is to call
dst_negative_advice which will attempt to choose a different ECMP route,
reset the TX hash for flow label and UDP source port in encapsulation,
etc.

This facility should be useful for connected UDP sockets where only the
application can provide any feedback about path quality. It could also
be useful for TCP applications that have additional knowledge about the
path outside of the normal TCP control loop.

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.

Merge branch 'parisc-4.5-1' of git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux

Pull parsic updates from Helge Deller:
 "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"

* 'parisc-4.5-1' of git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux:
  parisc: Protect huge page pte changes with spinlocks
  parisc: Imporove debug info about space registers and TLB configuration
  parisc: Drop parisc-specific NSIGTRAP define
  parisc: Fix __ARCH_SI_PREAMBLE_SIZE
  parisc: Reduce overhead of parisc_requires_coherency()
  parisc: Initialize PCI bridge cache line and default latency

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.
