940739196c iwlwifi: replace minimum slot time constant
There are a number of places where the minimum
slot time is hardcoded to 20 TU, add a new
constant for that and use it everywhere.

9b9190d968 iwlwifi: implement remain-on-channel
For device supporting PAN/P2P, use the PAN
context to implement the remain-on-channel
operation using device offloads so that the
filters in the device will be programmed
correctly -- otherwise we cannot receive
any probe request frames during off-channel
periods.

9d4dea7259 iwlagn: Enable idle powersave mode in 1000 series
The iwlagn powersave algorithm uses the supports_idle parameter
to tell the device to save power when it is not associated with
an AP and is idle.

Enable this feature for the 1000 series of devices.

24834d2c84 iwlwifi: correct debugfs data dumped from sram
the sram data dumped through the debugfs interface would only work properly
when dumping data on even u32 boundaries and swap bytes based on endianness
on that boundary making byte arrays impossible to read.

now addresses are displayed at the start of every line and the data is
displayed consistently if dumping 1 byte or 20 and regardless of what is the
starting address.

if no lenght given, address displayed is u32 in device format

Use -E... instead of just E... in a few places where negative error
codes are expected by a functions callers.  These were found by grepping
with coccinelle & then inspecting by hand to determine which were bugs.

The staging/cxt1e1 driver appears to intentionally use positive E...
error codes in some places, and negative -E... error codes in others,
making it hard to know which is intended where - very likely I missed
some problems in that driver.

2f644ccfc5 staging: comedi: Make INSN_BITS behavior consistent across drivers
Most comedi hardware drivers that support the INSN_BITS instruction
ignore the base channel (specified by insn->chanspec) and assume it is
0.  The base channel is supposed to affect how the mask (in data[0]) and
bits (in data[1]) are treated.  Bit 0 applies to the base channel, bit 1
applies to base channel plus 1, etc.

For subdevices with no more than 32 channels, this patch modifies the
chanspec and data before presenting it to the hardware driver, and
modifies the data bits read back by the hardware driver (into data[1]).
This makes it appear to the hardware driver that the base channel was
set to 0.

For subdevices with more than 32 channels, the instruction is left
unmodified, as it is assumed that the hardware driver takes note of the
base channel in this case in order to provide access beyond channel 31.

59eb21a650 cfg80211: Extend channel to frequency mapping for 802.11j
Extend channel to frequency mapping for 802.11j Japan 4.9GHz band, according to
IEEE802.11 section 17.3.8.3.2 and Annex J. Because there are now overlapping
channel numbers in the 2GHz and 5GHz band we can't map from channel to
frequency without knowing the band. This is no problem as in most contexts we
know the band. In places where we don't know the band (and WEXT compatibility)
we assume the 2GHz band for channels below 14.

This patch does not implement all channel to frequency mappings defined in
802.11, it's just an extension for 802.11j 20MHz channels. 5MHz and 10MHz
channels as well as 802.11y channels have been omitted.

The following drivers have been updated to reflect the API changes:
iwl-3945, iwl-agn, iwmc3200wifi, libertas, mwl8k, rt2x00, wl1251, wl12xx.
The drivers have been compile-tested only.
