Move to keeping the SoC registers that control and config the PCI
controllers on FSL SoCs in the pci_controller struct. This allows us to
not need to ioremap() the registers in multiple different places that

Currently we use the link register to branch up high in the early MMU on
syscall entry path. Unfortunately, this trashes the link stack as the
address we are going to is not associated with the earlier mflr.
This patch simply converts us to used the count register (volatile over
syscalls anyway) instead. This is much better at predicting in this
scenario and doesn't trash link stack causing a bunch of additional
branch mispredicts later. Benchmarking this on POWER8 saves a bunch of
cycles on Anton's null syscall benchmark here:

Pull signal/compat fixes from Al Viro:
"Fixes for several regressions introduced in the last signal.git pile,

compat: restore timerfd settime and gettime compat syscalls
[regression] braino in "sparc: convert to ksignal"
fix compat truncate/ftruncate
switch lseek to COMPAT_SYSCALL_DEFINE
lseek() and truncate() on sparc really need sign extension
I'm not sure why, but the hlist for each entry iterators were conceived
list_for_each_entry(pos, head, member)
The hlist ones were greedy and wanted an extra parameter:
hlist_for_each_entry(tpos, pos, head, member)
Why did they need an extra pos parameter? I'm not quite sure. Not only
they don't really need it, it also prevents the iterator from looking
exactly like the list iterator, which is unfortunate.
Besides the semantic patch, there was some manual work required:
- Fix up the actual hlist iterators in linux/list.h
- Fix up the declaration of other iterators based on the hlist ones.
- A very small amount of places were using the 'node' parameter, this
was modified to use 'obj->member' instead.
- Coccinelle didn't handle the hlist_for_each_entry_safe iterator
properly, so those had to be fixed up manually.
