Merge tag 'omap-fixes-b-for-v3.8-rc' of git://git.kernel.org/pub/scm/linux/kernel/git/pjw/omap-pending into omap-for-v3.8-rc4/fixes
A few OMAP integration fixes for v3.8-rc, for OMAP4 audio and OMAP2 reboot.
Basic test logs are available here:
http://www.pwsan.com/omap/testlogs/prcm_fixes_c_v3.8-rc/20130121073904/
The init_completion() call does reinit not only the variable carrying
the flag that the completion finished, but also initialized the
waitqueue associated with the completion. On the contrary, the
INIT_COMPLETION() call only reinits the flag.
In case there was anything still stuck in the waitqueue, subsequent call
to init_completion() would be able to create possible race condition. This
patch uses the proper function and moves init_completion() into .probe() call
of the driver, to be issued only once.
Note that such scenario is impossible, since two threads can never enter the
mxs_i2c_xfer_msg(), since whole this section is protected by mutex in I2C core.
This by no means allows this issue to exit though.

This patch eventually fixes two issues:
- Handle the case where the primary output is a headphone and can have
independent HP mode;
so far we checked only the case where the headphone is the secondary
output.
- Fix the conflict of HP independent mode and aamix mode;
when switched to aamix mode, the DAC might be also switched to
another widget shared with other outputs. Then even if we disable
the DAC for the original output, it doesn't change -- because the
active route is from another (shared) DAC to HP pin through aamix.
So, in such a case, we have to prohibit the switch to aamix for HP
routes.
This fixes issues appearing on VT codecs.
Signed-off-by: Takashi Iwai <tiwai@suse.de>
Many codecs provide routes to multiple output pins through an aamix
widget, but most of them do it only from a single DAC. However, the
current generic parser checks only the aamix paths from the original
(directly bound) DACs through aamix NID, and miss the path:
primary DAC -> aamix -> target out pin
This patch adds a more check for the routes like the above.

On IPsec pmtu events we can't access the transport headers of
the original packet, so we can't find the socket that sent
the packet. The only chance to notify the socket about the
pmtu change is to force a relookup for all routes. This
patch implenents this for the IPsec protocols.

Support arbitrary linux socket filter (BPF) programs as x_tables
match rules. This allows for very expressive filters, and on
platforms with BPF JIT appears competitive with traditional
hardcoded iptables rules using the u32 match.
The size of the filter has been artificially limited to 64
instructions maximum to avoid bloating the size of each rule
using this new match.

struct sockaddr_in6 *vaddr6 = (struct sockaddr_in6 *) &rhs;
return ipv6_addr_equal(..., &vaddr6->sin6_addr);

which interpreted the values on the stack after the 'rhs' pointer as an
ipv6 address. The correct thing to do is to use 'rhs', not '&rhs'.

ARC relocatable object files contain one/more .gnu.linkonce.arcextmap.*
sections (collated by kernel/vmlinux.lds into .arcextmap in final link).
This section is used by debuggers to display the extension instructions
and need-not be loaded by target (hence !SHF_ALLOC)
The final kernel binary only needs .arcextmap entry in modpost's ignore
list (section_white_list[]). However when building modules, modpost scans
each object file individually, hence tripping on non-aggregated
.gnu.linkonce.arcextmap.* entries as well.
Thus need for the 2 entires !

Currently descriptors are allocated from normal cacheable memory and that slows
