Subject: sparc64: Don't use alloc_bootmem() in init_IRQ() code paths.

The page allocator and SLAB are available at this point now,
and if we still try to use bootmem allocations here the kernel
spits out warnings.

Subject: headers: smp_lock.h redux

* Remove smp_lock.h from files which don't need it (including some headers!)
* Add smp_lock.h to files which do need it
* Make smp_lock.h include conditional in hardirq.h
  It's needed only for one kernel_locked() usage which is under CONFIG_PREEMPT

  This will make hardirq.h inclusion cheaper for every PREEMPT=n config
  (which includes allmodconfig/allyesconfig, BTW)

Subject: sparc64: Sign extend length arg to truncate syscalls when compat.

The first thing sys_truncate() and sys_ftruncate() do is sign extend
the unsigned length arg to a signed type.

Thanks to Benjamin Herrenschmidt for the tip.

Subject: percpu, sparc64: fix sparse possible cpu map handling

percpu code has been assuming num_possible_cpus() == nr_cpu_ids which
is incorrect if cpu_possible_map contains holes.  This causes percpu
code to access beyond allocated memories and vmalloc areas.  On a
sparc64 machine with cpus 0 and 2 (u60), this triggers the following
warning or fails boot.

 ---[ end trace 429b268a213317ba ]---

This patch fixes generic percpu functions and sparc64
setup_per_cpu_areas() so that they handle sparse cpu_possible_map
properly.

Please note that on x86, cpu_possible_map() doesn't contain holes and
thus num_possible_cpus() == nr_cpu_ids and this patch doesn't cause
any behavior difference.

Subject: sparc: sys32.S incorrect compat-layer splice() system call

I think arch/sparc/kernel/sys32.S has an incorrect splice definition:

SIGN2(sys32_splice, sys_splice, %o0, %o1)

The splice() prototype looks like :

       long splice(int fd_in, loff_t *off_in, int fd_out,
                   loff_t *off_out, size_t len, unsigned int flags);

So I think we should have :

SIGN2(sys32_splice, sys_splice, %o0, %o2)

Subject: sparc32: Kill trap table freeing code.

Normally, srmmu uses different trap table register values to allow
determination of the cpu we're on.  All of the trap tables have
identical content, they just sit at different offsets from the first
trap table, and the offset shifted down and masked out determines
the cpu we are on.

The code tries to free them up when they aren't actually used
(don't have all 4 cpus, we're on sun4d, etc.) but that causes
problems.

For one thing it triggers false positives in the DMA debugging
code.  And fixing that up while preserving this relative offset
thing isn't trivial.

So just kill the freeing code, it costs us at most 3 pages, big
deal...

Subject: sparc64: Validate linear D-TLB misses.

When page alloc debugging is not enabled, we essentially accept any
virtual address for linear kernel TLB misses.  But with kgdb, kernel
address probing, and other facilities we can try to access arbitrary
crap.

So, make sure the address we miss on will translate to physical memory
that actually exists.

In order to make this work we have to embed the valid address bitmap
into the kernel image.  And in order to make that less expensive we
make an adjustment, in that the max physical memory address is
decreased to "1 << 41", even on the chips that support a 42-bit
physical address space.  We can do this because bit 41 indicates
"I/O space" and thus covers non-memory ranges.

The result of this is that:

1) kpte_linear_bitmap shrinks from 2K to 1K in size

2) we need 64K more for the valid address bitmap

We can't let the valid address bitmap be dynamically allocated
once we start using it to validate TLB misses, otherwise we have
crazy issues to deal with wrt. recursive TLB misses and such.

If we're in a TLB miss it could be the deepest trap level that's legal
inside of the cpu.  So if we TLB miss referencing the bitmap, the cpu
will be out of trap levels and enter RED state.

To guard against out-of-range accesses to the bitmap, we have to check
to make sure no bits in the physical address above bit 40 are set.  We
could export and use last_valid_pfn for this check, but that's just an
unnecessary extra memory reference.

On the plus side of all this, since we load all of these translations
into the special 4MB mapping TSB, and we check the TSB first for TLB
misses, there should be absolutely no real cost for these new checks
in the TLB miss path.

Subject: sparc64: Kill spurious NMI watchdog triggers by increasing limit to
 30 seconds.

This is a compromise and a temporary workaround for bootup NMI
watchdog triggers some people see with qla2xxx devices present.

This happens when, for example:

CPU 0 is in the driver init and looping submitting mailbox commands to
load the firmware, then waiting for completion.

CPU 1 is receiving the device interrupts.  CPU 1 is where the NMI
watchdog triggers.

CPU 0 is submitting mailbox commands fast enough that by the time CPU
1 returns from the device interrupt handler, a new one is pending.
This sequence runs for more than 5 seconds.

The problematic case is CPU 1's timer interrupt running when the
barrage of device interrupts begin.  Then we have:

	timer interrupt
	return for softirq checking
	pending, thus enable interrupts

		 qla2xxx interrupt
		 return
		 qla2xxx interrupt
		 return
		 ... 5+ seconds pass
		 final qla2xxx interrupt for fw load
		 return

	run timer softirq
	return

At some point in the multi-second qla2xxx interrupt storm we trigger
the NMI watchdog on CPU 1 from the NMI interrupt handler.

The timer softirq, once we get back to running it, is smart enough to
run the timer work enough times to make up for the missed timer
interrupts.

However, the NMI watchdogs (both x86 and sparc) use the timer
interrupt count to notice the cpu is wedged.  But in the above
scenerio we'll receive only one such timer interrupt even if we last
all the way back to running the timer softirq.

The default watchdog trigger point is only 5 seconds, which is pretty
low (the softwatchdog triggers at 60 seconds).  So increase it to 30
seconds for now.

Subject: sparc64: Fix bootup with mcount in some configs.

Functions invoked early when booting up a cpu can't use
tracing because mcount requires a valid 'current_thread_info()'
and TLB mappings to be setup.

The code path of sun4v_register_mondo_queues --> register_one_mondo
is one such case.  sun4v_register_mondo_queues already has the
necessary 'notrace' annotation, but register_one_mondo does not.

Normally register_one_mondo is inlined so the bug doesn't trigger,
but with some config/compiler combinations, it won't be so we
must properly mark it notrace.

While we're here, add 'notrace' annoations to prom_printf and
prom_halt so that early error handling won't have the same problem.
