This patch adds a Kconfig option for the avic irq controller
and lets the SoCs that need it select this option.
Also, as we have two irq controllers for i.MX, irq.c is not
appropriate anymore, so rename it to avic.c

The following patch is a first step to convert the 'struct pad_desc'
to a bitmapped cookie to facilitate adding platform specific pullup or
drive strength definitions to existing pad definitions without need to
rewrite the complete pad def.
The patch wraps 'struct pad_desc' in an opaque data type and
introduces macros to access the individual members.
This patch does not constitute any functional change!

* 'for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tytso/ext4:
ext4: Add EXT4_IOC_TRIM ioctl to handle batched discard
fs: Do not dispatch FITRIM through separate super_operation
ext4: ext4_fill_super shouldn't return 0 on corruption
jbd2: fix /proc/fs/jbd2/<dev> when using an external journal
ext4: missing unlock in ext4_clear_request_list()
ext4: fix setting random pages PageUptodate
Filesystem independent ioctl was rejected as not common enough to be in
core vfs ioctl. Since we still need to access to this functionality this
commit adds ext4 specific ioctl EXT4_IOC_TRIM to dispatch
ext4_trim_fs().
It takes fstrim_range structure as an argument. fstrim_range is definec in
the include/linux/fs.h and its definition is as follows.
struct fstrim_range {
__u64 start;
__u64 len;
__u64 minlen;
}
start - first Byte to trim
len - number of Bytes to trim from start
minlen - minimum extent length to trim, free extents shorter than this
number of Bytes will be ignored. This will be rounded up to fs
block size.
After the FITRIM is done, the number of actually discarded Bytes is stored
in fstrim_range.len to give the user better insight on how much storage
space has been really released for wear-leveling.

There was concern that FITRIM ioctl is not common enough to be included
in core vfs ioctl, as Christoph Hellwig pointed out there's no real point
in dispatching this out to a separate vector instead of just through
->ioctl.
So this commit removes ioctl_fstrim() from vfs ioctl and trim_fs
from super_operation structure.

This reverts commit 59365d136d.
It turns out that this can break certain existing user land setups.
Quoth Sarah Sharp:
"On Wednesday, I updated my branch to commit 460781b from linus' tree,
and my box would not boot. klogd segfaulted, which stalled the whole
system.
At first I thought it actually hung the box, but it continued booting
after 5 minutes, and I was able to log in. It dropped back to the
text console instead of the graphical bootup display for that period
of time. dmesg surprisingly still works. I've bisected the problem
down to this commit (commit 59365d136d)
The box is running klogd 1.5.5ubuntu3 (from Jaunty). Yes, I know
that's old. I read the bit in the commit about changing the
permissions of kallsyms after boot, but if I can't boot that doesn't
help."
So let's just keep the old default, and encourage distributions to do
the "chmod -r /proc/kallsyms" in their bootup scripts. This is not
worth a kernel option to change default behavior, since it's so easily
done in user space.
