This should fix a suspend/resume issues that appear with OHCI on some
PPC hardware. The PCI layer should doesn't have the hooks needed for
such ASIC-specific hooks (in this case, software clock gating), so
this moves the code to do that into hcd-pci.c ... where it can be
done after the relevant PCI PM state transition (to/from D3).

Moving the PCI-specific parts of the EHCI driver into their own file
created a few issues ... notably on resume paths which (like swsusp)
require re-initializing the controller. This patch:
- Splits the EHCI startup code into run-once HCD setup code and
separate "init the hardware" reinit code. (That reinit code is
a superset of the "early usb handoff" code.)
- Then it makes the PCI init code run both, and the resume code only
run the reinit code.
- It also removes needless pci wrappers around EHCI start/stop methods.
- Removes a byteswap issue that would be seen on big-endian hardware.
The HCD glue still doesn't actually provide a good way to do all this
run-one init stuff in one place though.

This cleans up the recent updates to EHCI PCI support:
- Gets rid of checks for "is this a PCI device", they're no
longer needed since this is now all PCI-only code.
- Reduce log spamming: MWI is only interesting in the atypical
case that it can actually be used.
- Whitespace cleanup, as appropriate for a new file with no
other pending patches.
So other than that minor logging change, no functional updates.

This fixes some bugs in EHCI suspend/resume that joined us over the past
few releases (as usbcore, PCI, pmcore, and other components evolved):
- Removes suspend and resume recursion from the EHCI driver, getting
rid of the USB_SUSPEND special casing.
- Updates the wakeup mechanism to work again; there's a newish usbcore
call it needs to use.
- Provide simpler tests for "do we need to restart from scratch", to
address another case where PCI Vaux was lost. (In this case it was
restoring a swsusp snapshot, but there could be others.)
Un-exports a symbol that was temporarily exported.
A notable change from previous version is that this doesn't move
the spinlock init, so there's still a resume/reinit path bug.

When attempting to hotadd a PCI card with a bridge on it, I saw
the kernel reporting resource collision errors even when there were
really no collisions. The problem is that the code doesn't skip
over "invalid" resources with their resource type flag not set.
Others have reported similar problems at boot time and for
non-bridge PCI card hotplug too, where the code flags a
resource collision for disabled ROMs. This patch fixes both
problems.

Fix a bug where setting the low fan speed limits will not work if no
data was ever read through the sysfs interface and the fan clock
dividers have not been explicitely set yet either. The reason is that
data->fan_div[nr] may currently be used before it is initialized from
the chip register values. The fix is to explicitely initialize
data->fan_div[nr] before using it.

Commit 7d24f0b8a53261709938ffabe3e00f88f6498df9 fixed bugs in the ppc64 SLB
miss handler with respect to hugepage handling, and in the process tweaked
the semantics of the hugepage address masks in mm_context_t.
Unfortunately, it left out a couple of necessary changes to go with that
change. First, the in_hugepage_area() macro was not updated to match,
second prepare_hugepage_range() was not updated to correctly handle
hugepages regions which straddled the 4GB point.
The latter appears only to cause process-hangs when attempting to map such
a region, but the former can cause oopses if a get_user_pages() is
triggered at the wrong point. This patch addresses both bugs.

If unregister_console() is inadvertently called while no consoles are
registered, it will crash trying to dereference NULL pointer. It is
necessary to fix that because register_console() provides no indication
that it actually registered the console passed in. In fact, it may well
decide not to register it based on various things...
(akpm: It'd be better to make register_console() return something and fix the
callers. All 106 of them...)

When non-leader thread does exec, de_thread adds old leader to the init's
->children list in EXIT_ZOMBIE state and drops tasklist_lock.
This means that release_task(leader) in de_thread() is racy vs do_wait()
from init task.
I think de_thread() should set old leader's state to EXIT_DEAD instead.

Fix a bug in kprobes that can cause an Oops or even a crash when a return
probe is installed on one of the following functions: sys_execve,
do_execve, load_*_binary, flush_old_exec, or flush_thread. The fix is to
remove the call to kprobe_flush_task() in flush_thread(). This fix has
been tested on all architectures for which the return-probes feature has
been implemented (i386, x86_64, ppc64, ia64). Please apply.
BACKGROUND
Up to now, we have called kprobe_flush_task() under two situations: when a
task exits, and when it execs. Flushing kretprobe_instances on exit is
correct because (a) do_exit() doesn't return, and (b) one or more
return-probed functions may be active when a task calls do_exit(). Neither
is the case for sys_execve() and its callees.
Initially, the mistaken call to kprobe_flush_task() on exec was harmless
because we put the "real" return address of each active probed function
back in the stack, just to be safe, when we recycled its
kretprobe_instance. When support for ppc64 and ia64 was added, this safety
measure couldn't be employed, and was eventually dropped even for i386 and
x86_64. sys_execve() and its callees were informally blacklisted for
return probes until this fix was developed.

identical blocks, when handling the rare case of a futex in a nonlinear vma.
get_user_pages will itself do that follow_page, and its additional

just delete the follow_page block and let get_user_pages do it.

Closer attention to the arithmetic shows that neither ppc64 nor sparc really
uses one page for multiple page tables: how on earth could they, while
pte_alloc_one returns just a struct page pointer, with no offset?
Well, arm26 manages it by returning a pte_t pointer cast to a struct page
pointer, harumph, then compensating in its pmd_populate. But arm26 is never
SMP, so it's not a problem for split ptlock either.
And the PA-RISC situation has been recently improved: CONFIG_PA20 works
without the 16-byte alignment which inflated its spinlock_t. But the current
union of spinlock_t with private does make the 7xxx struct page significantly
larger, even without debug, so disable its split ptlock.
