This patch is preparation for replacing all uses of ".head.text" or
".text.head" in the kernel with macros, so that the section name can
later be changed without having to touch a lot of the kernel.
Since some linker scripts do more complex things than referencing
HEAD_TEXT, we add a HEAD_TEXT_SECTION macro that just contains the
actual name.
I've defined HEAD_TEXT_SECTION in a new header,
include/linux/section-names.h, so that this section name only needs to
appear in one place. I anticipate creating similar macro structures
for a number of other section names.
The long-term goal here is to be able to change the kernel's magic
section names to those that are compatible with -ffunction-sections
-fdata-sections. This requires renaming all magic sections with names
of the form ".text.foo".

The SO_MSGLIMIT socket option modifies the message limit for new
IUCV communication paths.
The message limit specifies the maximum number of outstanding messages
that are allowed for connections. This setting can be lowered by z/VM
when an IUCV connection is established.
Expects an integer value in the range of 1 to 65535.
The default value is 65535.
The message limit must be set before calling connect() or listen()
for sockets.
If sockets are already connected or in state listen, changing the message
limit is not supported.
For reading the message limit value, unconnected sockets return the limit
that has been set or the default limit. For connected sockets, the actual
message limit is returned. The actual message limit is assigned by z/VM
for each connection and it depends on IUCV MSGLIMIT authorizations
specified for the z/VM guest virtual machine.

The maximum sleep interval, for powersave purposes, is
determined by the DTIM period (it may not be larger)
and the required networking latency (it must be small
enough to fulfil those constraints).
This makes mac80211 calculate the maximum sleep interval
based on those constraints, and pass it to the driver.
Then the driver should instruct the device to sleep at
most that long.
Note that the device is responsible for aligning the
maximum sleep interval between DTIMs, we make sure it's
not longer but it needs to make sure it's between them.
Also, group some powersave documentation together and
make it more explicit that we support managed mode only,
and no IBSS powersaving (yet).

The TIM IE must not be shorter than 4 bytes, so verify that

Because other people may need the function, make it a static

Trying to separate header files into net/wireless.h and
net/cfg80211.h has been a source of confusion. Remove
net/wireless.h (because there also is the linux/wireless.h)
and subsume everything into net/cfg80211.h -- except the
definitions for regulatory structures which get moved to
a new header net/regulatory.h.
The "new" net/cfg80211.h is now divided into sections.
There are no real changes in this patch but code shuffling
and some very minor documentation fixes.
I have also, to make things reflect reality, put in a
copyright line for Luis to net/regulatory.h since that

This adds IBSS API along with (preliminary) wext handlers.
The wext handlers can only do IBSS so you need to call them
from your own wext handlers if the mode is IBSS.
The nl80211 API requires
* an SSID
* a channel (frequency) for the case that a new IBSS
has to be created
It optionally supports
* a flag to fix the channel
* a fixed BSSID
The cfg80211 code also takes care to leave the IBSS before
the netdev is set down. If wireless extensions are used, it
also caches values when the interface is down and instructs
the driver to join when the interface is set up.

libertas: add support for Marvell SD8688 chip
Use RxPD->pkt_ptr to locate eth803 header in the packet

RxPD and eth803 header.
Set SDIO block size to 256 for CMD53.
The maximum block size for SD8688 WLAN function is set
to 512 in TPLFE_MAX_BLK_SIZE. But using 512 as block size
results upto 2K bytes data (4 blocks) being transferred
and causes buffer overflow in firmware.
