All ARM binutils versions post 2.11.90 contains an extra "feature" which
interferes with the kernel in various ways - extra "mapping symbols"
in the ELF symbol table '$a', '$t' and '$d'.  This causes two problems:

1. Since '$a' symbols have the same value as function names, this
   causes anything which uses the kallsyms infrastructure to report
   wrong values.
2. programs which parse System.map do not expect symbols to start with
   '$'.

The following set of patches is based loosely on the patches that
Jean-Christophe Dubois came up with for 2.6.7.  Where as the original
patches added a number of casts to unsigned char, I went the route of
making the chars be explicitly signed.  I honestly don't know which
route is better to go down.  Doing this is the bulk of the patch.  Out
of the rest of the odds 'n ends is that on Solaris, Elf32_Word is a
ulong, which means all of the printf's are unhappy (uint format, ulong
arg) for most of the typedefs.

This patch adds pci_get_legacy_ide_irq() to the PCI layer for dealing
with PCI IDE chipsets that use the "legacy mode" IRQ routing, thus
violating the normal PCI routing.  The generic implementation provides
IRQ numbers 14 and 15, and it adds a ppc64 specific one with platform
callbacks so that a plaform can provide different IRQ numbers for "legacy"
IDE.  I only fixed the amd7xxx.c driver for now, I expect people using
this interface will slowly fix their drivers (I will fix via soon as I'll
need it too, and maybe a few others).

ide-iops.c exports a few functions that either have no users or have no
users AND shouldn't be used by drivers; the patch below unexports them.

-EXPORT_SYMBOL(SELECT_INTERRUPT);
-EXPORT_SYMBOL(SELECT_MASK);
-EXPORT_SYMBOL(QUIRK_LIST);
-EXPORT_SYMBOL(ata_vlb_sync);

only used in the core ide code

-EXPORT_SYMBOL(ata_input_data);
-EXPORT_SYMBOL(ata_output_data);

drivers should (and do) use the hwif-> function pointer variant of these,
these functions are internal and used for setting the default hwif->
function pointers only. No need to export, in fact exporting is only asking
for accidents

Optimize away the unconditional write to debug registers on signal delivery
path.  This is already done on x86_64.

We only need to write to dr7 if there is a breakpoint to re-enable, and 
MOVDR is a serializing instruction, which is expensive.  Getting rid of 
it gets a 33% faster signal delivery path (at least on Xeon - I didn't
test other CPUs, so your gain may vary).

[ Editors note: it's likely only that slow on Netburst.  Serializing is
  not that expensive, but it is likely that writing to %db7 invalidates
  the trace cache, which explains why it's so slow on Xeon - it's not
  just the op itself, it has to re-populate the cache all the time.
					--- Linus ]


Measured delta TSC for three paths on a 2.4GHz Xeon.

1) With unconditional write to dr7 :  800-1000 cycles
2) With conditional write to dr7   :  84-112 cycles
3) With unlikely write to dr7      :  84 cycles

Performance test using divzero microbenchmark (3 million divide by zeros):

With unconditional write:
   7.445 real / 6.136 system
   7.529 real / 6.482 system
   7.541 real / 5.974 system
   7.546 real / 6.217 system
   7.445 real / 6.167 system

With unlikely write:
   5.779 real / 4.518 system
   5.783 real / 4.591 system
   5.552 real / 4.569 system
   5.790 real / 4.528 system
   5.554 real / 4.382 system

That's about a 33% speedup - more than I expected; apparently getting rid
of the serializing instruction makes the do_signal path much faster.

In general it is not safe to do any non-ptrace wakeup of a thread in
TASK_TRACED, because the waking thread could race with a ptrace call
that could be doing things like mucking directly with its kernel stack. 

AFAIK noone has established that whatever clobberation ptrace can do to
a running thread is safe even if it will never return to user mode, so
we can't allow this even for SIGKILL.

What we _can_ safely do is make a thread switching out of TASK_TRACED
resume rather than sitting in TASK_STOPPED if it has a pending SIGKILL
or SIGCONT.  The following patch does this.

This should be sufficient for the shutdown case.  When killing all
processes, if the tracer gets killed first, the tracee goes into
TASK_STOPPED and will be woken and killed by the SIGKILL (same as
before).  If the tracee gets killed first, it gets a pending SIGKILL and
doesn't wake up immediately--but, now, when the tracer gets killed, the
tracee will then wake up to die. 

This will also fix the (same) situations that can arise now where you
have used gdb (or whatever ptrace caller), killed -9 the gdb and the
process being debugged, but still have to kill -CONT the process before
it goes away (now it should just go away either the first time or when
you kill gdb).
