The code in fbmem.c:fb_blank() is broken.  For drivers without an fb_blank
hook, an FBIO_BLANK ioctl will produce wrong colors or will segfault.

This does _not_ handle the conditional ones (lock_kernel and the
trylock variants), so there will be a fair number of context
error warnings with this. However, the warnings are disabled by
default in sparse - you have to use "-Wcontext" to see them.

This just sets up the portability defines.

I hadn't realized this was supposed to be an official interface.
Or maybe it's not, but the fb drivers all use it.   Anyway...

- redefine "printk" as "srm_printk" for bootstrappers;
- fix stack corruption problem with bootp/bootpz loaders and older
  SRM consoles.

The high order bits of the input address should be cleared only after
IO type and base are determined.

- add missing "__user" annotations in csum_partial_copy.c;
- make io_remap_page_range more readable and fix a warning.

While looking at the signal.c coredumping BUG_ON race, I noticed a bug
(not directly related) in do_coredump.  It was setting the "core dumped"
flag even when the format dumping hook failed (e.g.  for memory
allocation failures).
Signed-off-by: Linus Torvalds <torvalds@osdl.org>

This is indeed a new bug, and it is not architecture-specific.  In my
recent changes to close some race conditions, I overlooked the case of a
process using PTRACE_ATTACH on its own children.  The new PT_ATTACHED flag
does not really mean "PTRACE_ATTACH was used", it means "PTRACE_ATTACH is
changing the ->parent link".

This fixes the problem that Stephane Eranian program demonstrates.

Oh, duh.  The race is obvious.  Sorry for the confusion there.

The BUG_ON's were useful for debugging, since they trigger on a lot of
errors, but they _also_ trigger on some unlikely (but valid) races.

So just remove them - just fall through to the regular exit code after
core-dumping (which does everything right).

Doing access control checks with rq_lock held can cause deadlock when
audit messages are created (via printk or audit infrastructure) which
trigger a wakeup and deadlock, as noted by both SELinux and SubDomain
folks.  This patch will let the security checks happen w/out lock held,
then re-sample the p->policy in case it was raced. 

Originally from John Johansen <johansen@immunix.com>, reworked by me.
AFAIK, this version drew no objections from Ingo or Andrea.

This marks sets change_bits to all ones when bringing up a hub, since
not all hubs seem to send change events for devices that were plugged in
when the hub was reset.

The recent patch to scrub out ep0 state earlier (to get rid of some of
the enumeration problems that started with about 2.6.6) requires EHCI
to handle endpoint_disable() calls in a slightly different context.

This makes those calls work when an endpoint's QH may still be on the
async schedule, rather than already unlinked.  (The QH stays on the async
schedule for a few milliseconds after it's empty, since it's routine to
issue another request almost immediately.)

This has minor PCI tweaks for the EHCI driver:

  - If the (nonfunctional) AMD 8111 controller shows up, ignore it.
    (Patch from Matt Dharm, with minor coding style tweaks).

  - Delete some code that interprets an EHCI capability code; it
    should be a PCI capability instead.
