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.

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

12 years agortc: Avoid accumulating time drift in suspend/resume
John Stultz [Fri, 27 May 2011 18:33:18 +0000 (11:33 -0700)]
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.

This patch also improves some of the variable names and adds more clear

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

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: allow get_card_status() to return error status

If the MMC_SEND_STATUS command is not successful, we should not return
a zero status word, but instead allow the caller to know positively
that an error occurred.

Convert the open-coded get_card_status() to use the helper function,

This is patch for Conexant codec of Intel HDA driver, adding new quirk
for Lenovo Thinkpad T520 and W520. Conexant autodetection works fine for
T520 (similar subsystem ID is used also in W520 model) and detects more
mixer features compared to generic (fallback) Lenovo quirk with
hardcoded options in Conexant codec.

Patch was activelly tested with Linux 3.0.4, 3.0.6 and 3.0.7 without any
problems.
