The touchscreen GPIO IRQ was used as a magic number. Define it properly in the

This patch adds support for the on-board IDE channel. I tested this with a CDROM
connected over 2.5-3.5 IDE reduction with external power supplied to the CDROM.
This was not tested with the Voipac 270-HDD-000 (official Voipac HDD module),
but I expect no problems.

PXA_SSP is actually used by drivers like drivers/spi/pxa2xx_spi.c and

The previous definitions of SSCR0_SCR and SSCR0_SerClkDiv() prevented
them being used simultaneously when supporting multiple PXA SoCs, esp.
in drivers/spi/pxa2xx_spi.c, make them correct.
The change from SSCR0_SerClkDiv(2) to SSCR0_SCR(2), will make the result
a little bit different in pxa2xx_spi_probe(), however, since that's only
used as a default initialization value, it's acceptable.

The corgi touchscreen is now deprecated in favour of the generic ads7846.c
driver. The noise reduction technique used in corgi_ts.c, which is to wait
till vsync before ADC sampling, is also integrated into ads7846 driver now.
Provided that the original driver is not generic and is difficult to maintain,
it will be removed now.

Both Stephane and Corey reported that PERF_FORMAT_GROUP didn't
work as expected if the task the counters were attached to quit
before the read() call.
The cause is that we unconditionally destroy the grouping when
we remove counters from their context. Fix this by splitting off
the group destroy from the list removal such that
perf_event_remove_from_context() does not do this and change
perf_event_release() to do so.

Fix kprobe/x86 to check removed int3 when failing to get kprobe
from hlist. Since we have a time window between checking int3
exists on probed address and getting kprobe on that address,
we can have following scenario:
-------
CPU1 CPU2
hit int3
check int3 exists
remove int3
remove kprobe from hlist
get kprobe from hlist
no kprobe->OOPS!
-------
This patch moves int3 checking if there is no kprobe on that
address for fixing this problem as follows:
------
CPU1 CPU2
hit int3
remove int3
remove kprobe from hlist
get kprobe from hlist
no kprobe->check int3 exists
->rollback&retry

The raw_field_ptr() helper, used to retrieve the address of a field
inside a trace event, treats every strings as if they were dynamic
ie: having a secondary level of indirection to retrieve their
contents.
FIELD_IS_STRING doesn't mean FIELD_IS_DYNAMIC, we only need to
compute the secondary dereference for the latter case.
This fixes perf sched segfaults, bad cmdline report and may be
some other bugs.
