nl80211/cfg80211: add match filtering for sched_scan
Introduce filtering for scheduled scans to reduce the number of
unnecessary results (which cause useless wake-ups).
Add a new nested attribute where sets of parameters to be matched can
be passed when starting a scheduled scan. Only scan results that
match any of the sets will be returned.
At this point, the set consists of a single parameter, an SSID. This
can be easily extended in the future to support more complex matches.

commit

On v7, we use the same cache maintenance instructions for data lines

was defined to indicate the L1 cache topology.
This patch removes the erroneous compile-time check for HARVARD_CACHE in

rtc: Avoid accumulating time drift in suspend/resume
Because the RTC interface is only a second granular interface,
each time we read from the RTC for suspend/resume, we introduce a
half second (on average) of error.
In order to avoid this error accumulating as the system is suspended
over and over, this patch measures the time delta between the RTC
and the system CLOCK_REALTIME.
If the delta is less then 2 seconds from the last suspend, we compensate
by using the previous time delta (keeping it close). If it is larger
then 2 seconds, we assume the clock was set or has been changed, so we
do no correction and update the delta.
Note: If NTP is running, ths could seem to "fight" with the NTP corrected
time, where as if the system time was off by 1 second, and NTP slewed the
value in, a suspend/resume cycle could undo this correction, by trying to
restore the previous offset from the RTC. However, without this patch,
since each read could cause almost a full second worth of error, its
possible to get almost 2 seconds of error just from the suspend/resume
cycle alone, so this about equal to any offset added by the compensation.
Further on systems that suspend/resume frequently, this should keep time
closer then NTP could compensate for if the errors were allowed to
accumulate.
Credits to Arve Hjønnevåg for suggesting this solution.

tcp: Don't nuke connections for the wrong protocol
Currently, calling tcp_nuke_addr to reset IPv6 connections
resets IPv4 connections as well, because all Android
framework sockets are dual-stack (i.e., IPv6) sockets, and
we don't check the source address to see if the connection
was in fact an IPv4 connection.
Fix this by checking the source address and not resetting
the connection if it's a mapped address.
Also slightly tweak the IPv4 code path, which doesn't check
for mapped addresses either. This was not causing any
problems because tcp_is_local normally always returns true
for LOOPBACK4_IPV6 (127.0.0.6), because the loopback
interface is configured as as 127.0.0.0/8. However,
checking explicitly for LOOPBACK4_IPV6 makes the code a bit
more robust.

mm: avoid livelock on !__GFP_FS allocations
Under the following conditions, __alloc_pages_slowpath can loop
forever:
gfp_mask & __GFP_WAIT is true
gfp_mask & __GFP_FS is false
reclaim and compaction make no progress
order <= PAGE_ALLOC_COSTLY_ORDER
The gfp conditions are normally invalid, because !__GFP_FS
disables most of the reclaim methods that __GFP_WAIT would
wait for. However, these conditions happen very often during
suspend and resume, when pm_restrict_gfp_mask() effectively
converts all GFP_KERNEL allocations into __GFP_WAIT.
The oom killer is not run because gfp_mask & __GFP_FS is false,
but should_alloc_retry will always return true when order is less
than PAGE_ALLOC_COSTLY_ORDER. __alloc_pages_slowpath will
loop forever between the rebalance label and should_alloc_retry,
unless another thread happens to release enough pages to satisfy
the allocation.
Add a check to detect when PM has disabled __GFP_FS, and do not
retry if reclaim is not making any progress.

mmc: block: improve error recovery from command channel errors
Command channel errors fall into four classes:
1. The command was issued with the card in the wrong state
2. The command failed to be received by the card correctly
3. The cards response failed to be received by the host (CRC error)
4. The card failed to respond to the card
For (1), in theory we should know that the card is in the correct state.
However, a failed stop command (or other failure) may result in the card
remaining in a data transfer state from the previous command. If we
detect this condition, we try to recover by sending a stop command.
For the initial commands (set block count and the read/write command)
no data will have been transferred. All that we need deal with is
retrying at this point. A failed stop command can be remedied as
above.
If we are unable to recover the card (eg, the card ignores our requests
for status, or we don't recognise the error code) then we immediately
fail the request.

crypto: ghash - Avoid null pointer dereference if no key is set
commit
7ed47b7d142ec99ad6880bbbec51e9f12b3af74c upstream.
The ghash_update function passes a pointer to gf128mul_4k_lle which will
be NULL if ghash_setkey is not called or if the most recent call to
ghash_setkey failed to allocate memory. This causes an oops. Fix this
up by returning an error code in the null case.
This is trivially triggered from unprivileged userspace through the
AF_ALG interface by simply writing to the socket without setting a key.
The ghash_final function has a similar issue, but triggering it requires
a memory allocation failure in ghash_setkey _after_ at least one
successful call to ghash_update.

x25: Prevent skb overreads when checking call user data
commit
7f81e25befdfb3272345a2e775f520e1d515fa20 upstream.
x25_find_listener does not check that the amount of call user data given
in the skb is big enough in per-socket comparisons, hence buffer
overreads may occur. Fix this by adding a check.

mm: fix race between mremap and removing migration entry
commit
486cf46f3f9be5f2a966016c1a8fe01e32cde09e upstream.
I don't usually pay much attention to the stale "? " addresses in
stack backtraces, but this lucky report from Pawel Sikora hints that
mremap's move_ptes() has inadequate locking against page migration.
3.0 BUG_ON(!PageLocked(p)) in migration_entry_to_page():
kernel BUG at include/linux/swapops.h:105!

mremap's down_write of mmap_sem, together with i_mmap_mutex or lock,
and pagetable locks, were good enough before page migration (with its
requirement that every migration entry be found) came in, and enough
while migration always held mmap_sem; but not enough nowadays, when
there's memory hotremove and compaction.
The danger is that move_ptes() lets a migration entry dodge around
behind remove_migration_pte()'s back, so it's in the old location when
looking at the new, then in the new location when looking at the old.
Either mremap's move_ptes() must additionally take anon_vma lock(), or
migration's remove_migration_pte() must stop peeking for is_swap_entry()
before it takes pagetable lock.
Consensus chooses the latter: we prefer to add overhead to migration
than to mremapping, which gets used by JVMs and by exec stack setup.

hwmon: (w83627ehf) Fix negative 8-bit temperature values
commit
133d324d82e144588939ad25b732b5b6c33b03d9 upstream.
Since 8-bit temperature values are now handled in 16-bit struct
members, values have to be cast to s8 for negative temperatures to be
properly handled. This is broken since kernel version 2.6.39

x86: Fix S4 regression
commit
8548c84da2f47e71bbbe300f55edb768492575f7 upstream.
Commit
4b239f458 ("x86-64, mm: Put early page table high") causes a S4
regression since 2.6.39, namely the machine reboots occasionally at S4
resume. It doesn't happen always, overall rate is about 1/20. But,
like other bugs, once when this happens, it continues to happen.
This patch fixes the problem by essentially reverting the memory
assignment in the older way.
