Long awaited, hard work. This patch totally cleans up the rate control
API to remove the requirement to include internal headers outside of
net/mac80211/.
There's one internal use in the PID algorithm left for mesh networking,
we'll have to figure out a way to clean that one up and decide how to
do the peer link evaluation, possibly independent of the rate control
algorithm or via new API.
Additionally, ath9k is left using the cross-inclusion hack for now, we
will add new API where necessary to make this work properly, but right
now I'm not expert enough to do it. It's still off better than before.

When I split off the action frame handling I made the code drop
all action frames we don't want to handle. This is wrong since
some action frames are actually handled via rx_h_mgmt through
being queued to the sta/mesh implementations.

This patch removes the HT flags from RXON when moving from HT to legacy.
This avoids keeping those flags set and possibly miss configuring firmware.
If we are configured in HT, fat channel: channel 1 above, and move later
to legacy channel 11, we need to clear the FAT channel control flags in
RXON. If we don't, the firmware will understand this as channel 11 above
which is not possible due to regulatory constraints, leading to firmware
crash.

There's no need to register the master netdev with cfg80211,
in fact, this is quite dangerous and lead to having to add
checks for the master interface all over the config handlers.
This patch removes the "ieee80211_ptr" from the master iface
in favour of having a small netdev_priv() associated with
the master interface that stores the ieee80211_local pointer.
Because of this, a lot of code in the configuration handlers
can go away. To make this patch easier to verify I have also
removed a number of wiphy_priv() calls in favour of getting
the sdata first and then the local pointer from that.

The SIOCSIWSCAN handler is passed data in an iw_point structure. Some
drivers erronously use an iw_param instead.
On 32 bit architectures the difference isn't noticed as the flags
parameter tends to be the only one used by scan handlers and is at the
same offset.
On 64 bit architectures the pointer in the iw_point structure means the
flag parameter is at different offsets in these structures.

Roskin for confirming the fix and identifying other suspect handlers.

This is another relatively naive conversion. Always do the read upfront
when the page is not uptodate (unless we're in the writethrough path).
Fix an uninitialized data exposure where SetPageUptodate was called
before the page was uptodate.

cifs: work around samba returning -ENOENT on SetFileDisposition call
Samba seems to return STATUS_OBJECT_NAME_NOT_FOUND when we try to set
the delete on close bit after doing a rename by filehandle. This looks
like a samba bug to me, but a lot of servers will do this. For now,
pretend an -ENOENT return is a success.
Samba does however seem to respect the CREATE_DELETE_ON_CLOSE bit
when opening files that already exist. Windows will ignore it, but
so adding it to the open flags should be harmless.
We're also currently ignoring the return code on the rename by
filehandle, so no need to set rc based on it.

Boardrev is always treated as a u32 everywhere else, no reason to
byteswap the 0xc2 value. The only use is to print out if it is
a prerelease board, the test being:
(olpc_platform_info.boardrev & 0xf) < 8
Which is currently always true as be32_to_cpu(0xc2) & 0xf = 0
but I doubt that was the intention here. The consequences of the bug
are pretty minor though (incorrect boardrev displayed in dmesg when
ofw support not configured)
Also annotate the temporary used to read the boardrev in the ofw
case.
The confusion was noticed by Sparse:

When we use > 4KB's page size the original definition is not consistent
with PGDIR_SIZE. For exeample, if we use 16KB page size the PGDIR_SHIFT is
(14-2) + 14 = 26, PGDIR_SIZE is 2^26，so the PTRS_PER_PGD should be:
2^32/2^26 = 2^6
but the original definition of PTRS_PER_PGD is 4096 (PGDIR_ORDER = 0).
So, this definition needs to be consistent with the PGDIR_SIZE.
And the new definition is consistent with the PGD init in pagetable_init().
