Implement many of the hcd cleanups that David Brownell had previously submitted.

As was discussed a few weeks back, this moves most of the
sanity checks and input conditioning for the HCD framework's
usb_submit_urb() support directly into usb_submit_urb(), so
that all HCDs (not just those using the sharable HCD framework
support) can rely on them.

This has two minor tweaks to the uhci-hcd driver:

- removes some duplicated code (HCD framework does that test)
- corrects a FIXME comment (no issue)

This patch allows ov511 to build again by removing references to
urb->next. It now resubmits in the completion handler and properly sets
urb->interval.

This turns the simple task pointer into a waitqueue, which is
needed for the poll() patch.

Another trivial part of a Matthew Wilcox patch.  This just
defines macros for distinguishing the differnet types of locks.

This uses page_cache_release() instead of put_page(), as it might
be a pagecache page.

This patch handles the case where copy_from_user fails (it could
have been unmapped from this address space by another thread).

This comment refers to the original implementation. Obsolete.

This switches linux/zlib.h to include zconf.h as <linux/zconf.h> instead of
just "zconf.h".

printing Sparc IRQ.

Generic BUS objects have to be registered before
devices assosciated with them are probed.  Therefore
subsys_initcall is inappropriate for such setups.
It does not work to use core_initcall for this because
the generic device layer bits need to be setup first too.
So we rename unused_initcall to postcore_initcall and use
this new initcall level for generic BUS object init.
This fixes bootup on Alpha, and Sparc64.  X86 was working
by what looks to be luck in link order.

HAVE_ARCH_SIGINFO_T platforms.

Currently, drivers/usb/core/drivers.c includes <linux/mm.h> to get at
<linux/gfp.h>.  The following includes <linux/gfp.h> directly.

swsusp kind-of abused include/asm-i386/suspend.h for stuff that
belonged to arch/i386/kernel/suspend.c. This moves code where it
belongs.

So here we are: make vmlinux/bzImage/whatever will now also build
modules as it goes. Other than that, everything works as usual.
"make modules" builds only the modules (but you shouldn't need
it anymore). If you don't want the modules built, you can
do "make KBUILD_MODULES= vmlinux/whatever" to only compile built-in
objects.

If people want it, I can also allow for "make vmlinux/whatever nomodules"
to do the same.

Also, add '  ' in Rules.make to properly align output in quiet mode.
