This patch does a few small cleanups around the atmel mci platform code
and in the atmel-mci driver.  The platform changes simply removes an
unused variable, uses the fact that by the end we always have some form
of platform data and notes that GPIO_PIN_NONE != 0.  This last point
could cause the incorrect attempt to twice reserve pin PA0.

While we've got the hood up, add linux/err.h to the atmel-mci.c include
list.  It needs it and generally pulls it by voodoo but I did once
stumble across a config which don't build.

This is against Linus' latest git.

Compiling a kernel with allmodconfig or allyesconfig results in tons
of gcc warnings, because the default maximum stacksize from which on

-tip testing found a bootup hang here:

  initcall anon_inode_init+0x0/0x130 returned 0 after 0 msecs
  calling  acpi_event_init+0x0/0x57

the bootup should have continued with:

  initcall acpi_event_init+0x0/0x57 returned 0 after 45 msecs

but it hung hard there instead.

bisection led to this commit:

| Date:   Mon Jul 14 16:11:52 2008 +0200
|     Merge branch 'auto-ftrace-next' into tracing/for-linus

turns out that i made this mistake in the merge:

  ifdef CONFIG_FTRACE
  # Do not profile debug utilities
  CFLAGS_REMOVE_tsc_64.o = -pg
  CFLAGS_REMOVE_tsc_32.o = -pg

those two files got unified meanwhile - so the dont-profile annotation
got lost. The proper rule is:

  CFLAGS_REMOVE_tsc.o = -pg

i guess this could have been caught sooner if the CFLAGS_REMOVE* kbuild
rule aborted the build if it met a target that does not exist anymore?

This reverts commit 809d9a8f.

This one isn't quite ready for prime time.  It needs more testing and
additional feedback from the ACPI guys.

"idle=nomwait" disables the use of the MWAIT
instruction from both C1 (C1_FFH) and deeper (C2C3_FFH)
C-states.

When MWAIT is unavailable, the BIOS and OS generally
negotiate to use the HALT instruction for C1,
and use IO accesses for deeper C-states.

This option is useful for power and performance
comparisons, and also to work around BIOS bugs
where broken MWAIT support is advertised.

"idle=halt" limits the idle loop to using
the halt instruction.  No MWAIT, no IO accesses,
no C-states deeper than C1.

If something is broken in the idle code,
"idle=halt" is a less severe workaround
than "idle=poll" which disables all power savings.

991528d7
(ACPI: Processor native C-states using MWAIT)
started passing C2C3_FFH to _PDC to tell the BIOS
that Linux supports MWAIT for deep C-states.

However, we should first double check with the hardware
that it actually supports MWAIT before potentially exposing
a BIOS bug of an MWAIT _CST on HW that doesn't support MWAIT.

Using ACPI to find free address space allows us to find a gap for the
unallocated PCI resources or MMIO resources for hotplug devices within
the BIOS allowed PCI regions.

It works by evaluating the _CRS object under PCI0 looking for producer
resources.  Then searches the e820 memory space for a gap within these
producer resources.
