This is what a lot of drivers will actually want to use to insert
individual pages into a user VMA.  It doesn't have the old PageReserved
restrictions of remap_pfn_range(), and it doesn't complain about partial
remappings.

The page you insert needs to be a nice clean kernel allocation, so you
can't insert arbitrary page mappings with this, but that's not what
people want.

This fixes a NULL pointer reference in DRM.  The SiS driver tries to

Rename the EHCI "reset" routine so it better matches what it does (setup);
and move the one-time data structure setup earlier, before doing anything
that implicitly relies on it having been completed already.

This patch closes the IRQ race and makes various other OHCI & EHCI code
path safer vs. suspend/resume.
I've been able to (finally !) successfully suspend and resume various
Mac models, with or without USB mouse plugged, or plugging while asleep,
or unplugging while asleep etc... all without a crash.

Alan, please verify the UHCI bit I did, I only verified that it builds.
It's very simple so I wouldn't expect any issue there. If you aren't
confident, then just drop the hunks that change uhci-hcd.c

I also made the patch a little bit more "safer" by making sure the store
to the interrupt register that disables interrupts is not posted before
I set the flag and drop the spinlock.

Without this patch, you cannot reliably sleep/wakeup any recent Mac, and
I suspect PCs have some more sneaky issues too (they don't frankly crash
with machine checks because x86 tend to silently swallow PCI errors but
that won't last afaik, at least PCI Express will blow up in those
situations, but the USB code may still misbehave).

Access to a journaled HFS+ volume is not officially supported under Linux, so
mount such a volume read-only, but users can override this behaviour using the
"force" mount option.

The minimum requirement to relax this check is to at least check that the
journal is empty and so nothing needs to be replayed to make sure the volume
is consistent.

If an external device is used for a journal, by default it will use the
entire device.  The reiserfs journal code allocates structures per journal
block when it mounts the file system.  If the journal device is too large,
and memory cannot be allocated for the structures, it will continue and
ultimately panic when it can't pull one off the free list.

This patch handles the allocation failure gracefully and prints an error
message at mount time.

Changes: Updated error message to be more descriptive to the user.

set_page_dirty() will not cope with being handed a page * which is part of
a compound page, but not the master page in that compound page.  This case
can occur via access_process_vm() if you attemp to write to another
process's hugepage memory area using ptrace() (causing an oops or hang).

This patch fixes the bug by only calling set_page_dirty() from
access_process_vm() if the page is not a compound page.  We already use a
similar fix in bio_set_pages_dirty() for the case of direct io to
hugepages.

The uid_t and gid_t fields appear to present a 32/64-bit userspace/kernel
problem for some archs.

This patch addresses the problem by fixing the size to the largest size for
uid_t/gid_t used in the kernel.  This preserves the total size of the event
structure while ensuring that the layouts of the ID change event match in
32 and 64-bit kernels and applications.

This fixes the arch/powerpc code by adding preempt_disable/enable,

any lazily-switched CPU register state into a new function, rather
than having that code repeated in three places.
