The ftrace output events can have either arguments or no
arguments. The parser needs to be able to handle both.

The bprintk parsing was broken in more ways than one.
The file parsing was incorrect, and the words used by the
arguments are always 4 bytes aligned, even on 64-bit machines.

Even though an event may fail to parse, we should not kill the
entire report. The trace should still be able to show what it
can.
If an event fails to parse, a warning is printed, and the output
continues.

The trace format files now have a "signed" field. But we should
still be able to handle the kernels that do not have this field.

New lines between args in the trace format can break the

The '*' is currently only treated as a multiplication, and it
needs to be handled as a typecast pointer.

The array used by the ftrace stack events (caller[x]) causes
issues with the parser. This adds code to handle the case, but
it also assumes that the array is of type long.
Note, this is a special case used (currently) only by the ftrace
user and kernel stack records.

The Unit_Characteristics entry of an SBP-2 unit directory is not
mandatory as far as I can tell. If it is missing, we would probably
fail to log in into the target because firewire-sbp2 would not wait for
status after it sent the login request.
The fix moves the cleanup of tgt->mgt_orb_timeout into a place where it
is executed exactly once before login, rather than 0..n times depending
on the target's config ROM. With targets with one or more
Unit_Characteristics entries, the result is the same as before.

Thanks to tip form ARM folks and Russell King.
If flush_dcache_page() occurs on a swapin it will have a mapping
and we'll try to defer the flush by setting the dirty bit.
But when it hits update_dcache_page() we won't flush because the
page won't have a mapping any more. So remove the mapping
requirement in flush_dcache().

Use cio_is_console() in io_subchannel_probe to indicate that the
special handling is console specific. As long as there is no other
subchannel for which this might be true, it is misleading to speak
of "early devices". Should more of these devices be introduced,
a cleanup of all console special handling is in order anyway.

The reason for that is an error in the request queue handling. It can
happen that we fetch a request, but do not process it further because
the number of queued requests exceeds TAPEBLOCK_MIN_REQUEUE.
To fix this, we should call blk_peek_request() instead of
blk_fetch_request() in the while condition and fetch the request in
the loop body afterwards.
This bug was introduced with the patch "block: implement and enforce
request peek/start/fetch" (9934c8c04561413609d2bc38c6b9f268cba774a4)

The resume_userspace path had TRACE_IRQS_OFF written incorrectly and so
never handled the transition properly. This was fixed once before but
seems to have made it back in the tree. Fix it for good.

This only needs to flush the return code via the legacy path, and just
invalidates uselessly otherwise. This makes the behaviour consistent for
all of the trampoline setup paths.

The secondary CPU info was seeing corrupted results due to not entering
all of the setup paths taken by the boot CPU. So we just memcpy() the
boot cpu data over directly, and then fix up the per-CPU bits.

Trivial change for cleaning up the cpuinfo pretty printing on SMP, adds a

We do not want to use smp_processor_id() from these paths, as they trip
preempt BUGs. Switch the test over to the boot cpu directly.

Sync up with latest core changes in the syscalls tracing area:
- tracing: Map syscall name to number (syscall_name_to_nr())
- tracing: Call arch_init_ftrace_syscalls at boot
- tracing: add support tracepoint ids (set_syscall_{enter,exit}_id())
Taken from the s390 change.

This too follows the ARM change, given that the issue at hand applies to
all platforms that implement lazy D-cache writeback.
This fixes up the case when a page mapping disappears between the
flush_dcache_page() call (when PG_dcache_dirty is set for the page) and
the update_mmu_cache() call -- such as in the case of swap cache being
freed early. This kills off the mapping test in update_mmu_cache() and
switches to simply testing for PG_dcache_dirty.

This follows the ARM change, as SH had all of the same issues:
Make die() better match x86:
- add printing of the last accessed sysfs file
- ensure console_verbose() is called under the lock
- ensure we panic outside of oops_exit()

A race shouldn't happen since all workqueues or handlers are canceled
or flushed before the event buffer is freed. A warning is triggered
now if the buffer is freed too early.
Also, this patch adds some comments about event buffer protection,
reworks some code and adds code to clear buffer_pos during alloc and
free of the event buffer.

Looking at the 2.6.31-rc9 code, it appears there is a race condition
in the event_buffer cleanup code path (shutdown). This could lead to
kernel panic as some CPUs may be operating on the event buffer AFTER
it has been freed. The attached patch solves the problem and makes
sure CPUs check if the buffer is not NULL before they access it as
some may have been spinning on the mutex while the buffer was being
freed.
The race may happen if the buffer is freed during pending reads. But
it is not clear why there are races in add_event_entry() since all
workqueues or handlers are canceled or flushed before the event buffer
is freed.

Some tracepoint magic (TRACE_EVENT(lock_acquired)) relies on
the fact that lock hold times are positive and uses div64 on
that. That triggered a build warning on MIPS, and probably
causes bad output in certain circumstances as well.
Make it truly positive.
