mac80211: make ieee80211_iterate_active_interfaces not need rtnl
rt2500usb and rt73usb broke down due to attempting register access
in atomic context (which is not possible for USB hardware).
This patch restores ieee80211_iterate_active_interfaces() to use RTNL lock,
and provides the non-RTNL version under a new name:
ieee80211_iterate_active_interfaces_atomic()
So far only rt2x00 uses ieee80211_iterate_active_interfaces(), and those
drivers require the RTNL version of ieee80211_iterate_active_interfaces().
Since they already call that function directly, this patch will automatically
fix the USB rt2x00 drivers.
v2: Rename ieee80211_iterate_active_interfaces_rtnl

This adds a function to put a 6xx/7xx/7xxx/83xx family CPU into sleep
mode, and return after an interrupt has occurred. It expects to be
called with interrupts disabled, and returns with interrupts disabled.
Interrupts are enabled while the processor is asleep, but the interrupt
that wakes the processor is not handled; it is still pending when this
function returns.

This provides a way to defer processing of an interrupt that wakes the
processor out of sleep mode. On 32-bit platforms that use an
interrupt to wake the processor, we have to have interrupts enabled in
hardware at the point where we go to sleep, otherwise the processor
will never wake up. However, because interrupts are logically
disabled at this point, we don't want to process the interrupt
straight away.
This is handled by setting the _TLF_SLEEPING flag. When we get an
interrupt and _TLF_SLEEPING is set, we firstly clear the MSR_EE
(external interrupt enable) bit in the saved MSR value, and secondly
we then return to the address in the link register, like we do for
_TLF_NAPPING, but without actually handling the interrupt.
Note that this is handled somewhat differently on powerbooks, so this
new code will only be used on non-Apple machines.

Everybody wants to pass it a function pointer, and in fact, that is what
you _must_ pass it for it to make sense (since it knows that ia64 and
ppc64 use descriptors for function pointers and fetches the actual
address from there).
So don't make the argument be a 'unsigned long' and force everybody to
add a cast.

Calls to copy_to_user() or copy_from_user() can fail when copying N
bytes, where N is a constant less than 8, but not 1, 2, 4, or 8,
because 'ret' is not initialized and is only set if the size is 1,
2, 4 or 8, but is tested after the switch statement for any constant
size <= 8. This fixes it by initializing 'ret' to 1, causing the
code to fall through to the __copy_tofrom_user call for sizes other
than 1, 2, 4 or 8.

This changes vmemmap to use a different region (region 0xf) of the
address space, and to configure the page size of that region
dynamically at boot.
The problem with the current approach of always using 16M pages is that
it's not well suited to machines that have small amounts of memory such
as small partitions on pseries, or PS3's.
In fact, on the PS3, failure to allocate the 16M page backing vmmemmap
tends to prevent hotplugging the HV's "additional" memory, thus limiting
the available memory even more, from my experience down to something
like 80M total, which makes it really not very useable.
The logic used by my match to choose the vmemmap page size is:
- If 16M pages are available and there's 1G or more RAM at boot,
use that size.
- Else if 64K pages are available, use that
- Else use 4K pages
I've tested on a POWER6 (16M pages) and on an iSeries POWER3 (4K pages)
and it seems to work fine.
Note that I intend to change the way we organize the kernel regions &
SLBs so the actual region will change from 0xf back to something else at
one point, as I simplify the SLB miss handler, but that will be for a
later patch.

The atm_tcp.h uses types from linux/atm.h, but does not include it.
It should also use the standard __u## types from linux/types.h rather
than the uint##_t types since the former can be found with the kernel
already.
Same goes for linux/atm.h. The linux/socket.h include there also gets
dropped as atm.h does not actually use anything from socket.h.

Current module loader lookups ".data.percpu" ELF section to perform
per_cpu relocation. But DEFINE_PER_CPU_SHARED_ALIGNED() uses another
section (".data.percpu.shared_aligned"), currently only handled in
vmlinux.lds, not by module loader.
To correct this problem, instead of adding logic into module loader, or
using at build time a module.lds file for all arches to group
".data.percpu.shared_aligned" into ".data.percpu", just use ".data.percpu"
for modules.
Alignment requirements are correctly handled by ld and module loader.
