      Remove useless wrappers of asm-generic/rmap.h · 459dac82
      Paul Bolle 提交于
      xtensa has a header (in its include/asm directory) that is a thin
      wrapper around asm-generic/rmap.h. This wrapper is useless, since that
      header doesn't exist. It is also unused (no file includes asm/rmap.h).
      
      openrisc generates a similar header at build time (using a generic-y
      entry in include/asm/Kbuild). This generated header is useless and
      unused too.
      
      Remove this header and this generic-y entry.

      xtensa: fix build fail on undefined ack_bad_irq · 8e12a038
      Paul Gortmaker 提交于
      Commit e520c410
      
          "xtensa: convert to asm-generic/hardirq.h"
      
      converted over to using the asm-generic parts, but it also
      added the sentinel
      
      	#define ack_bad_irq ack_bad_irq
      
      which tells asm-generic to _not_ use the common ack_bad_irq.
      
      Since e520c410 deleted the duplicated code from the arch specific
      file, we _do_ want the asm-generic one in scope.  So delete
      the trigger define above which hides it.  In doing so we'll
      realize that we've got to delete the almost-duplicate prototype
      as well to avoid "static declaration ... follows non-static".

      coredump: add VM_NODUMP, MADV_NODUMP, MADV_CLEAR_NODUMP · accb61fe
      Jason Baron 提交于
      Since we no longer need the VM_ALWAYSDUMP flag, let's use the freed bit
      for 'VM_NODUMP' flag.  The idea is is to add a new madvise() flag:
      MADV_DONTDUMP, which can be set by applications to specifically request
      memory regions which should not dump core.
      
      The specific application I have in mind is qemu: we can add a flag there
      that wouldn't dump all of guest memory when qemu dumps core.  This flag
      might also be useful for security sensitive apps that want to absolutely
      make sure that parts of memory are not dumped.  To clear the flag use:
      MADV_DODUMP.

      sock: Introduce the SO_PEEK_OFF sock option · ef64a54f
      Pavel Emelyanov 提交于
      This one specifies where to start MSG_PEEK-ing queue data from. When
      set to negative value means that MSG_PEEK works as ususally -- peeks
      from the head of the queue always.
      
      When some bytes are peeked from queue and the peeking offset is non
      negative it is moved forward so that the next peek will return next
      portion of data.
      
      When non-peeking recvmsg occurs and the peeking offset is non negative
      is is moved backward so that the next peek will still peek the proper
      data (i.e. the one that would have been picked if there were no non
      peeking recv in between).
      
      The offset is set using per-proto opteration to let the protocol handle
      the locking issues and to check whether the peeking offset feature is
      supported by the protocol the socket belongs to.

      PCI: Xtensa: convert pcibios_set_master() to a non-inlined function · 9cdce18d
      Myron Stowe 提交于
      This patch converts Xtensa's architecture-specific
      'pcibios_set_master()' routine to a non-inlined function.  This will
      allow follow on patches to create a generic 'pcibios_set_master()'
      function using the '__weak' attribute which can be used by all
      architectures as a default which, if necessary, can then be over-
      ridden by architecture-specific code.
      
      Converting 'pci_bios_set_master()' to a non-inlined function will
      allow Xtensa's 'pcibios_set_master()' implementation to remain
      architecture-specific after the generic version is introduced and
      thus, not change current behavior.
      
      No functional change.

      net: add wireless TX status socket option · 6e3e939f
      Johannes Berg 提交于
      The 802.1X EAPOL handshake hostapd does requires
      knowing whether the frame was ack'ed by the peer.
      Currently, we fudge this pretty badly by not even
      transmitting the frame as a normal data frame but
      injecting it with radiotap and getting the status
      out of radiotap monitor as well. This is rather
      complex, confuses users (mon.wlan0 presence) and
      doesn't work with all hardware.
      
      To get rid of that hack, introduce a real wifi TX
      status option for data frame transmissions.
      
      This works similar to the existing TX timestamping
      in that it reflects the SKB back to the socket's
      error queue with a SCM_WIFI_STATUS cmsg that has
      an int indicating ACK status (0/1).
      
      Since it is possible that at some point we will
      want to have TX timestamping and wifi status in a
      single errqueue SKB (there's little point in not
      doing that), redefine SO_EE_ORIGIN_TIMESTAMPING
      to SO_EE_ORIGIN_TXSTATUS which can collect more
      than just the timestamp; keep the old constant
      as an alias of course. Currently the internal APIs
      don't make that possible, but it wouldn't be hard
      to split them up in a way that makes it possible.
      
      Thanks to Neil Horman for helping me figure out
      the functions that add the control messages.

      ns: Wire up the setns system call · 7b21fddd
      Eric W. Biederman 提交于
      32bit and 64bit on x86 are tested and working.  The rest I have looked
      at closely and I can't find any problems.
      
      setns is an easy system call to wire up.  It just takes two ints so I
      don't expect any weird architecture porting problems.
      
      While doing this I have noticed that we have some architectures that are
      very slow to get new system calls.  cris seems to be the slowest where
      the last system calls wired up were preadv and pwritev.  avr32 is weird
      in that recvmmsg was wired up but never declared in unistd.h.  frv is
      behind with perf_event_open being the last syscall wired up.  On h8300
      the last system call wired up was epoll_wait.  On m32r the last system
      call wired up was fallocate.  mn10300 has recvmmsg as the last system
      call wired up.  The rest seem to at least have syncfs wired up which was
      new in the 2.6.39.
      
      v2: Most of the architecture support added by Daniel Lezcano <dlezcano@fr.ibm.com>
      v3: ported to v2.6.36-rc4 by: Eric W. Biederman <ebiederm@xmission.com>
      v4: Moved wiring up of the system call to another patch
      v5: ported to v2.6.39-rc6
      v6: rebased onto parisc-next and net-next to avoid syscall  conflicts.
      v7: ported to Linus's latest post 2.6.39 tree.

      bitops: remove minix bitops from asm/bitops.h · 61f2e7b0
      Akinobu Mita 提交于
      minix bit operations are only used by minix filesystem and useless by
      other modules.  Because byte order of inode and block bitmaps is different
      on each architecture like below:
      
      m68k:
      	big-endian 16bit indexed bitmaps
      
      h8300, microblaze, s390, sparc, m68knommu:
      	big-endian 32 or 64bit indexed bitmaps
      
      m32r, mips, sh, xtensa:
      	big-endian 32 or 64bit indexed bitmaps for big-endian mode
      	little-endian bitmaps for little-endian mode
      
      Others:
      	little-endian bitmaps
      
      In order to move minix bit operations from asm/bitops.h to architecture
      independent code in minix filesystem, this provides two config options.
      
      CONFIG_MINIX_FS_BIG_ENDIAN_16BIT_INDEXED is only selected by m68k.
      CONFIG_MINIX_FS_NATIVE_ENDIAN is selected by the architectures which use
      native byte order bitmaps (h8300, microblaze, s390, sparc, m68knommu,
      m32r, mips, sh, xtensa).  The architectures which always use little-endian
      bitmaps do not select these options.
      
      Finally, we can remove minix bit operations from asm/bitops.h for all
      architectures.
