      net: add wireless TX status socket option · 6e3e939f
      由 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.

      compat: sync compat_stats with statfs. · 1448c721
      由 Eric W. Biederman 提交于 
      This was found by inspection while tracking a similar
bug in compat_statfs64, that has been fixed in mainline
since decemeber.

- This fixes a bug where not all of the f_spare fields
  were cleared on mips and s390.
- Add the f_flags field to struct compat_statfs
- Copy f_flags to userspace in case someone cares.
- Use __clear_user to copy the f_spare field to userspace
  to ensure that all of the elements of f_spare are cleared.
  On some architectures f_spare is has 5 ints and on some
  architectures f_spare only has 4 ints.  Which makes
  the previous technique of clearing each int individually
  broken.

I don't expect anyone actually uses the old statfs system
call anymore but if they do let them benefit from having
the compat and the native version working the same.

      Revert "MIPS: LD/SD o32 macro GAS fix update" · b77bb37a
      由 Ralf Baechle 提交于 
      This reverts commit 97475f8b42e83be2966aa2d70ab9c98477701c53 (lmo) /
82b89152 (kernel.org) [MIPS: LD/SD o32
macro GAS fix update].

Turns out this patch is producing many build errors with gcc 4.2.  Based
on further testing with a test case extracted from the build errors found
further build errors and suboptimal generation even in violation of the
"R" constraint.

To make matters worse, the binutils changes also don't work quite as
intended so revert this patch for now.

      MIPS: SNI: Fix conflicting wrapper symbols for headers. · dd5d1380
      由 Ralf Baechle 提交于 
      If Open Firmware / Device Tree support is enabled on a SNI RM kernel both
<asm/mipsprom.h> and <asm/prom.h> will be included into some .c files.
Since both headers use the same wrapper symbol only the inclusion of the
first file will have an effect but the 2nd file will be ignored resulting
in a build error.

      MIPS: cache: Provide cache flush operations for XFS · d9cdc901
      由 Ralf Baechle 提交于 
      Until now flush_kernel_vmap_range() and invalidate_kernel_vmap_range() did
not exist on MIPS resulting in heavy cache corruption on XFS filesystems.

Left for the post-3.0 time: optimization and make this work with highmem,
too.  Since the combination of highmem + cache aliases atm doesn't work
this isn't a regression.

      doc: fix broken references · 395cf969
      由 Paul Bolle 提交于 
      There are numerous broken references to Documentation files (in other
Documentation files, in comments, etc.). These broken references are
caused by typo's in the references, and by renames or removals of the
Documentation files. Some broken references are simply odd.

Fix these broken references, sometimes by dropping the irrelevant text
they were part of.
