autofs4 - remove ioctl mutex (bz23142)
With the recent changes to remove the BKL a mutex was added to the
ioctl entry point for calls to the old ioctl interface. This mutex
needs to be removed because of the need for the expire ioctl to call
back to the daemon to perform a umount and receive a completion
status (via another ioctl).
This should be fine as the new ioctl interface uses much of the same
code and it has been used without a mutex for around a year without
issue, as was the original intention.

PM / Hibernate: Fix memory corruption related to swap
There is a problem that swap pages allocated before the creation of
a hibernation image can be released and used for storing the contents
of different memory pages while the image is being saved. Since the
kernel stored in the image doesn't know of that, it causes memory
corruption to occur after resume from hibernation, especially on
systems with relatively small RAM that need to swap often.
This issue can be addressed by keeping the GFP_IOFS bits clear
in gfp_allowed_mask during the entire hibernation, including the
saving of the image, until the system is finally turned off or
the hibernation is aborted. Unfortunately, for this purpose
it's necessary to rework the way in which the hibernate and
suspend code manipulates gfp_allowed_mask.
This change is based on an earlier patch from Hugh Dickins.

PM / Hibernate: Use async I/O when reading compressed hibernation image
This is a fix for reading LZO compressed image using async I/O.
Essentially, instead of having just one page into which we keep
reading blocks from swap, we allocate enough of them to cover the
largest compressed size and then let block I/O pick them all up. Once
we have them all (and here we wait), we decompress them, as usual.
Obviously, the very first block we still pick up synchronously,
because we need to know the size of the lot before we pick up the
rest.
Also fixed the copyright line, which I've forgotten before.

UBI: fix corrupted PEB detection for NOR flash
My new shiny code for corrupted PEB detection has NOR specific bug.
We tread PEB as corrupted and preserve it, if
1. EC header is OK.
2. VID header is corrupted.
3. data area is not "all 0xFFs"
In case of NOR we have 'nor_erase_prepare()' quirk, which invalidates
the headers before erasing the PEB. And we invalidate first the VID
header, and then the EC header. So if a power cut happens after we have
invalidated the VID header, but before we have invalidated the EC
header, we end up with a PEB which satisfies the above 3 conditions,
and the scanning code will treat it as corrupted, and will print
scary warnings, wrongly.
This patch fixes the issue by firt invalidating the EC header, then
invalidating the VID header. In case of power cut inbetween, we still
just lose the EC header, and UBI can deal with this situation gracefully.
Thanks to Anatolij Gustschin <agust@denx.de> for tracking this down.

iMX51: introduce IMX_GPIO_NR
Currently, to define a GPIO number, we're using something like :
#define EFIKAMX_PCBID0 (2*32 + 16)
to define GPIO 3 16.
This is not really readable and it's error prone imho (note the 3 vs 2).
So, I'm introducing a new macro to define this in a better way. Now, the
code sample become :
#define EFIKAMX_PCBID0 IMX_GPIO_NR(3, 16)
v2:
- move to gpio.h
- add parens & spaces
- switch to IMX_GPIO_NR instead of MX51_GPIO_NR
