56ef28acf1 OMAP4: PRCM: Define shift macros as n instead of 1 << n
The macros defining the shift bits in registers for various
register bit fields are defined as 1 << n.
Instead define them as n. They can then be used as val << n.
The changes are generated by updating the script which autogenerates
the files modifed in the patch.

e80a9729b1 OMAP2/3/4 clock: rename and clean the omap2_clk_init() functions
Rename the omap2_clk_init() in the OMAP2, 3, and 4 clock code to be
omap2xxx_clk_init(), omap3xxx_clk_init(), etc.  Remove all traces of
the (commented) old virt_prcm_set code from omap3xxx_clk_init() and
omap4xxx_clk_init(), since this will be handled with the OPP code that
is cooking in the PM branch.

After this patch, there should be very little else in the clock code
that blocks a multi-OMAP 2+3 kernel.  (OMAP2420+OMAP2430 still has some
outstanding issues that need to be resolved; this is pending on some
additions to the hwmod data.)

60c3f65191 OMAP3 DPLL: reorganize static functions
Move all static functions up to the top of the file to match the
practice in other OMAP clock code.  Make omap3_noncore_dpll_program()
static (noted by sparse) and prepend an underscore to the function

feec1277a5 OMAP2/3/4 clock: omap2_clk_prepare_for_reboot() is OMAP2xxx-only
omap2_clk_prepare_for_reboot() is only applicable to OMAP2xxx chips,
so rename it to omap2xxx_clk_prepare_for_reboot() and only call it when
running on OMAP2xxx chips.  Remove the old stub in the OMAP3 clock code.

In the OMAP3xxx clock code, remove the #ifdef CONFIG_ARCH_OMAP3 in
clock34xx.c, since this file is only compiled for OMAP3xxx builds.  Also,
rename omap2_clk_arch_init in this file to omap3xxx_clk_arch_init() to

on non-OMAP3xxx systems.

396c56a9c6 sh: Kill off broken type 1 PCI config access checks.
The host controllers only support type 1, so there's not much else to
test for. Some of the older controllers also supported type 2 accesses,
but we've never supported those, and likely never will. Beyond that, the
P1SEG test is meaningless for 32-bit mode, so rather than refactoring it,
just kill the type 1 test off completely.

05d43ed8a8 x86: get rid of the insane TIF_ABI_PENDING bit
Now that the previous commit made it possible to do the personality
setting at the point of no return, we do just that for ELF binaries.
And suddenly all the reasons for that insane TIF_ABI_PENDING bit go
away, and we can just make SET_PERSONALITY() just do the obvious thing
for a 32-bit compat process.

Everything becomes much more straightforward this way.

221af7f87b Split 'flush_old_exec' into two functions
'flush_old_exec()' is the point of no return when doing an execve(), and
it is pretty badly misnamed.  It doesn't just flush the old executable
environment, it also starts up the new one.

Which is very inconvenient for things like setting up the new
personality, because we want the new personality to affect the starting
of the new environment, but at the same time we do _not_ want the new
personality to take effect if flushing the old one fails.

As a result, the x86-64 '32-bit' personality is actually done using this
insane "I'm going to change the ABI, but I haven't done it yet" bit
(TIF_ABI_PENDING), with SET_PERSONALITY() not actually setting the
personality, but just the "pending" bit, so that "flush_thread()" can do
the actual personality magic.

This patch in no way changes any of that insanity, but it does split the
'flush_old_exec()' function up into a preparatory part that can fail
(still called flush_old_exec()), and a new part that will actually set
up the new exec environment (setup_new_exec()).  All callers are changed
to trivially comply with the new world order.

ed8777fc13 perf_events, x86: Fix event constraint masks
Since constraints are specified on the event number, not number
and unit mask shorten the constraint masks so that we'll
actually match something.

2e8418736d perf_event: x86: Deduplicate the disable code
Share the meat of the x86_pmu_disable() code with hw_perf_enable().

Also remove the barrier() from that code, since I could not convince
myself we actually need it.

6c9687abeb perf_event: x86: Optimize x86_pmu_disable()
x86_pmu_disable() removes the event from the cpuc->event_list[], however
since an event can only be on that list once, stop looking after we found
it.
