Gcc might re-order MMIO accessors vs. surrounding consistent

This fixes it by adding a "memory" clobber to the MMIO accessors,

libata: replace tf_read with qc_fill_rtf for non-SFF drivers

Broke the sata_fsl.c driver in 2.6.26-rc.  I know the following patch fixes
the issue, it clearly also adds port multipler support.  The current
2.6.26-rc driver is broken.

On boot with debug enabled we get something like (w/o this patch):

spurious interrupt!!, CC = 0x1
interrupt status 0x1
xx_scr_read, reg_in = 1
spurious interrupt!!, CC = 0x1
interrupt status 0x1
xx_scr_read, reg_in = 1
spurious interrupt!!, CC = 0x1
interrupt status 0x1
xx_scr_read, reg_in = 1

.. continues for ever.

This change fixes this as a side effect of adding port multiplier support.

ICH8M on macbooks are peculiar in that some of them lock up when the
second port is enabled, some return bogus values on SIDPR access while
yet others hang on SIDPR access.  Also, the ich8m_apple_sata entry was
wrongly added below generic ich8m entry making it virtually useless.

This patch works around macbook ich8m problems by

* moving ich8m_apple_sata entry above generic ich8m entry
* dropping PIIX_FLAG_SIDPR from ich8m_apple_sata
* adding subsystem 106b:00a1 as ich8m_apple_sata

The SW_RADIO code for EV_SW events has a name that is not descriptive
enough of its intended function, and could induce someone to think
KEY_RADIO is its EV_KEY counterpart, which is false.

Rename it to SW_RFKILL_ALL, and document what this event is for.  Keep
the old name around, to avoid userspace ABI breaks.

The SW_RFKILL_ALL event is meant to be used by rfkill master switches.  It
is not bound to a particular radio switch type, and usually applies to all
types.  It is semantically tied to master rfkill switches that enable or
disable every radio in a system.

The driver incorrectly assumed that putchar will only be called from

free output buffers where available.
Since putchar may also be called from BH context this may lead to
deadlocks.
To fix this just return the number of characters accepted and let the
upper layer handle the rest.

The console write function will busy wait (sclp_sync_wait) until a
