Hi,
In drivers/platform/x86/thinkpad_acpi.c::acpi_evalf() we don't always call
va_end() after va_start(). This patch corrects that.

The old code was using platform_driver.probe to initialize

eeepc_platform_register() won't tell anyone, and chaos will happen.
Wrap add and remove code inside eeepc_wmi_add() / eeepc_wmi_remove(),
and try to use the static platform_device only in eeepc_wmi_init()
and eeepc_wmi_exit()
The code is now very similar to eeepc-laptop, except eeepc_laptop_add
and eeepc_laptop_remove are called from acpi_driver, not module
init/exit functions, but WMI doesn't provide such functionalities (yet ?).

We don't need to call bios/acpi (cmpc_set_rfkill_wlan) if the blocked
state is already set to the same value (little optimization). This can
happen for example if we initialize the module with same initial
hardware state (rfkill core always call cmpc_rfkill_block on
initialization here).
Also GWRI method only accepts 0 or 1 for setting rfkill block, as can be
seen on AML code from acpidump->DSDT from a classmate sample I have, so
should be fine setting state only to 0 or 1 directly.

WMI data blocks can contain WMI events with the same GUID but with
different notifiy_ids, for example volume up/down hotkeys.
This patch enables a single event handler to be registered and
unregistered against all events with same GUID but different
notify_ids. Since an event handler is passed the notify_id of
an event it can can differentiate between the different events.
The patch also ensures we only register and unregister a device per
unique GUID.

I've no idea why this driver uses NULL for dma_unmap_single instead of
the &spi->dev that is laying around just waiting to be used in that
function - but it's an easy fix.
Also replace this comment with a FIXME comment:
/* Do DMA mapping "early" for better error reporting and
* dcache use. Note that if dma_unmap_single() ever starts
* to do real work on ARM, we'd need to clean up mappings
* for previous transfers on *ALL* exits of this loop...
*/
as the comment is not true - we do work in dma_unmap() functions,
particularly on ARMv6 and above. I've corrected the existing unmap
functions but if any others are required they must be added ASAP.

The test "if (spi_imx->irq <= 0)" is not testing the IRQ value, but
the return value of platform_get_irq(). As platform_get_irq() can
return an error (-ENXIO) or the IRQ value it found, the test should be
"if (spi_imx->irq < 0)"
[grant.likely: Note: In general, Linux irq number 0 should also mean
no irq, but arm still allows devices to be assigned 0, and the imx
platform uses 0 for one of the spi devices, so this patch is needed
for the device to work]

From the x86_64 low level interrupt handlers, the frame pointer is
saved right after the partial pt_regs frame.
rbp is not supposed to be part of the irq partial saved registers,
but it only requires to extend the pt_regs frame by 8 bytes to
do so, plus a tiny stack offset fixup on irq exit.
This changes a bit the semantics or get_irq_entry() that is supposed
to provide only the value of caller saved registers and the cpu
saved frame. However it's a win for unwinders that can walk through
stack frames on top of get_irq_regs() snapshots.
A noticeable impact is that it makes perf events cpu-clock and
task-clock events based callchains working on x86_64.
Let's then save rbp into the irq pt_regs.
