Add the necessary infrastructure to handle restartable syscalls via
the restart_block method.  This isn't perfect, since we are unable
to modify the syscall number with ARM executables (it's typically
encoded into the instruction in the text segment) so instead we
build some code on the user space stack.

There is a potential problem - what happens if we are sleeping,
someone suspends us, resume (we continue to sleep via the restart
block method) suspend and then resume again?  We will build two
sets of restart code on the user stack.  This is probably a little
inefficient, but it should be harmless.

Tricks like struct foo foo = { .bar.baz = 5, }; don't work.  We must
initialise child-structure members within their own block - ie,
struct foo foo = { .bar = { .baz = 5, }, };

The Acorn font file is used by the decompressor on some machines.
It moved location recently - so this cset fixes up the reference
to it.

This makes the following changes :
 o headers cleanup
 o remove deprecated kernel_only
 o mention minimum oprofile version
 o correct initialise stats
 o remove racy debug check (wli saw this oops)
 o remove pointless simple_open
 o add dump functionality
 o remove pessimising FASTCALL

It fixes a critical race.

This simple intermezzo Makefile change allows it to build.

This fixes the APM GDT entry allocation issue.  Confirmed by Andrew
Morton.

fast system calls. They should now be fully comparable to
traditional system calls.

    Fix SEP stack allocation to look like a real thread stack.
    
    This fixes the "Trap on first sysenter instruction" problem,
    which can happen either as a result of an NMI or a breakpoint
    trap (TF bit set).
    
    Also make the user trampoline save and restore EFLAGS, so that
    the TF bit gets restored after a fast system call (it will have
    been cleared to avoid trap faults in the kernel).

trampoline.

Here's how: we re-load %ebp (arg6) in the kernel sysenter handler
from the stack, and on system call re-play we jump back in user
space to re-initialize %ebp to point to the stack pointer before
re-doing the sysenter instruction.

vm86 does broken tasklist scanning for matching task_struct pointers,
which is oopsable. This registers a notifier for it to GC vm86 IRQ's in
release_thread() and removes the broken tasklist scanning.

This bugfix is in 2.4.x and has been in 2.5.x-dj for an extended period
of time.

This patch converts most common hub diagnostics to use the
device model diagnostic macros ... not all, someone should
reduce the number of err() strings for "bogus hub" cases,
and ideally streamline some of the dozen or so "here's what's
special about this new hub" dbg() messages.

So the messages become more useful:  they id the port (and
implicitly the device) involved, using a kernel-wide standard
convention.  Size overhead is smaller too.

For folk running with USB debugging enabled, it also cuts
the useless chatter on connections by deleting the per-poll
success messages and a partial dup message when things change.
And it deletes a newish diagnostic on a (non-hub) unlink path.

It also makes Pete's new debounce message use the right
port number -- one-based, not zero-based.

My main issue with this patch is that it doesn't change
more messages, but it seems reasonable to merge it anyway.

unknown ioctls return -ENOTTY and nothing else.

checking for -EINPROGRESS is wrong.

this makes sure that the kernel thread is dead and gone on module unload.
  - use a completion to wait for the kernel thread's death

Don't try to dereference the interrupt endpoint if it doesn't exist.

2.5.50 included a change from -ac which changed MSNDCLAS_HAVE_BOOT and
MSNDPIN_HAVE_BOOT to asked questions. This is wrong (I know since I was
the one who wrote the patch Alan picked up...).

They shouldn't ask questions, the following patch reverts my buggy
change.

The change to eata_pio_proc.c contained a typo: a semicolon instead of a
comma.

Move the 'vsyscall' page to 0xffffe000, leaving a hole at the top

Older gcc's do not support that form of ellipsis in a macro.
