_raw_spin_lock_flags() is entered with interrupts disabled. If it cannot
obtain a spinlock, it checks the flags that were passed and re-enables
interrupts before spinning if that's how the flags are set. When the
spinlock might be available, it disables interrupts (even if they are
already disabled) before trying to get the lock. Change that so interrupts
are only disabled if they have been enabled. This costs nine bytes of
duplicated spinloop code.
Fastpath before patch:
jle <keep looping> not-taken conditional jump
cli disable interrupts
jmp <try for lock> unconditional jump
Fastpath after patch, if interrupts were not enabled:
jg <try for lock> taken conditional branch

With cpu_gdt_descr having been converted to per-CPU data, the old object
(in head.S) no longer needs to reserve space for each CPU's instance. With
cpu_gdt_table not being used for CPU 0 anymore, it doesn't seem to need
page alignment (or if in fact there is a need for it to retain that
alignment, the whole object should go into .data.page_align).

I am of the opinion that the above changeset is incomplete, i.e. it missed
converting some previous uses of user_mode to user_mode_vm. While most of
them could be considered just cosmetical, at least the one in die_nmi
doesn't appear to be.

callbacks
Registering a callback handler through register_die_notifier() is obviously
primarily intended for use by modules. However, the way these currently
get called it is basically impossible for them to actually be used by
modules, as there is, on non-PAE configurationes, a good chance (the larger
the module, the better) for the system to crash as a result.
This is because the callback gets invoked
(a) in the page fault path before the top level page table propagation
gets carried out (hence a fault to propagate the top level page table
entry/entries mapping to module's code/data would nest infinitly) and
(b) in the NMI path, where nested faults must absolutely not happen,
since otherwise the IRET from the nested fault re-enables NMIs,
potentially resulting in nested NMI occurences.
Besides the modular aspect, similar problems would even arise for in-
kernel consumers of the API if they touched ioremap()ed or vmalloc()ed
memory inside their handlers.

The history is that -mm kernels do not work for me for a few months
already. The things started from crashing somewhere after starting init,
and for the last month - no boot at all, just "Uncompressing... OK,
booting kernel", and silence. Early console didn't work too. With the
latest releases this degraded into an infinite stream of the "Unknown
interrupt or fault" messages. So today my patience ran out and I started
to think how can I collect at least some info for the bug-report. Attached
is the patch that allows to gather some valueable debug info on the problem
by making an early console more useable. I can't properly test the patch,
as the kernel still doesn't boot, so I'll explain it in details in a hope
someone else can justify the intrusive changes.
arch_hooks.h: added prototypes for setup_early_printk() and early_printk().
setup.c: killed wrong setup_early_printk() prototype. Moved
setup_early_printk() a bit earlier, as it was not "early enough" to cover
the bug I was fighting with.
early_printk.c: made it to start printing from the bottom of the screen,
otherwise the messages interfere with the ones of the boot-loader, so you
can't read them.

In some code I am developing I had occasion to change the type of a
variable. This made the value put_user was putting to user space wrong.
But the code continued to build cleanly without errors.
Introducing a temporary fixes this problem and at least with gcc-3.3.5 does
not cause gcc any problems with optimizing out the temporary. gcc-4.x
using SSA internally ought to be even better at optimizing out temporaries,
so I don't expect a temporary to become a problem. Especially because in
all correct cases the types on both sides of the assignment to the
temporary are the same.

Implement SMP alternatives, i.e. switching at runtime between different
code versions for UP and SMP. The code can patch both SMP->UP and UP->SMP.
The UP->SMP case is useful for CPU hotplug.
With CONFIG_CPU_HOTPLUG enabled the code switches to UP at boot time and
when the number of CPUs goes down to 1, and switches to SMP when the number
of CPUs goes up to 2.
Without CONFIG_CPU_HOTPLUG or on non-SMP-capable systems the code is
patched once at boot time (if needed) and the tables are released
afterwards.
The changes in detail:
* The current alternatives bits are moved to a separate file,
the SMP alternatives code is added there.
* The patch adds some new elf sections to the kernel:
.smp_altinstructions
like .altinstructions, also contains a list
of alt_instr structs.
.smp_altinstr_replacement
like .altinstr_replacement, but also has some space to
save original instruction before replaving it.
.smp_locks
list of pointers to lock prefixes which can be nop'ed
out on UP.
The first two are used to replace more complex instruction
sequences such as spinlocks and semaphores. It would be possible
to deal with the lock prefixes with that as well, but by handling
them as special case the table sizes become much smaller.
* The sections are page-aligned and padded up to page size, so they
can be free if they are not needed.
* Splitted the code to release init pages to a separate function and
use it to release the elf sections if they are unused.

Print stack backtraces in multiple columns, saving screen space. Number of
columns is configurable and defaults to one so behavior is
backwards-compatible.
Also removes the brackets around addresses when printing more
that one entry per line so they print as:
<address>
instead of:
[<address>]
This helps multiple entries fit better on one line.

This patch address several issues in the current BSD Secure Levels code:
o plaintext_to_sha1: Missing check for a NULL return from __get_free_page
o passwd_write_file: A page is leaked if the password is wrong.
o fix securityfs registration order
o seclvl_init is a mess and can't properly tolerate failures, failure
path is upside down (deldif and delf should be switched)
Cleanups:
o plaintext_to_sha1: Use buffers passed in
o passwd_write_file: Use kmalloc() instead of get_zeroed_page()
o passwd_write_file: hashedPassword comparison is just memcmp
o s/ENOSYS/EINVAL/
o misc
(akpm: after some discussion it appears that the BSD secure levels feature
should be scheduled for removal. But for now, let's fix these problems up).

We have noticed lockups during boot when stress testing kexec on ppc64.
Two cpus would deadlock in scheduler code trying to grab already taken
spinlocks.
The double_rq_lock code uses the address of the runqueue to order the
taking of multiple locks. This address is a per cpu variable:
if (rq1 < rq2) {
spin_lock(&rq1->lock);
spin_lock(&rq2->lock);
} else {
spin_lock(&rq2->lock);
spin_lock(&rq1->lock);
}
On the other hand, the code in wake_sleeping_dependent uses the cpu id
order to grab locks:
for_each_cpu_mask(i, sibling_map)
spin_lock(&cpu_rq(i)->lock);
This means we rely on the address of per cpu data increasing as cpu ids
increase. While this will be true for the generic percpu implementation it
may not be true for arch specific implementations.
One way to solve this is to always take runqueues in cpu id order. To do
this we add a cpu variable to the runqueue and check it in the
double runqueue locking functions.

Remove the assumption that driver_register() returns the number of devices
bound to the driver. In fact, it returns zero for success or a negative
error value.
All callers of macio_register_driver() either ignore the return value or
return it as the return value of a module_init() function.

Nobody uses the return value of of_register_driver() anyway.

Now powerpc uses the generic RTC stuff we should not enable the old RTC.
Doing so will result in hangs at boot.

hi,
this fixes coverity bug #888, where the variable
dev is used uninitialized. I assume the programmer
meant to use mdev, which is initialized.
Compile tested only.
