GPIO IRQ unmask doesn't actually do anything useful. The problem is

One-shot mode was broken in MPU-timer support for OMAP1 due to a typo.
Also, ensure timer is stopped before changing the auto-reload flag.
The TRM says changing the AR flag when timer is running is undefined.
Also set GENERIC_CLOCKEVENTS for all omaps.

Move the definitions of ATAG_CORE and ATAG_CORE_SIZE in head.S to
head-common.S. There is no use of these in head.S itself, but they
are used in head-common.S. When building for the !CONFIG_MMU case
these were not defined when compiling head-nommu.S (which includes

This allows monitoring compile issues with Kautobuild for
other omap1 boards until we have more board specific defconfig
files.
After 2.6.25, we can add a generic config_omap_generic16xx to

boards from OSK defconfig.

H2 and H3 were broken on by e27a93a944a5ba6a0112750c8243abba86d56e94,
which removed declarations for their tps6501x chips. This resolves
that issue for the H2. (Note that this patch *also* broke the isp1301
support on H2; it presumed a not-yet-merged new-style I2c driver.)

Get rid of build warnings and errors in mainline for H3 boards; not

not getting proper build testing.
Also, commit e27a93a944a5ba6a0112750c8243abba86d56e94 introduced a
regression related to the tps65013 chip.

Add CONFIG_HAVE_KRETPROBES to the arch/<arch>/Kconfig file for relevant
architectures with kprobes support. This facilitates easy handling of
in-kernel modules (like samples/kprobes/kretprobe_example.c) that depend on
kretprobes being present in the kernel.
Thanks to Sam Ravnborg for helping make the patch more lean.
Per Mathieu's suggestion, added CONFIG_KRETPROBES and fixed up dependencies.

[ARM] Fix freeing of page tables for ARM in free_pgd_slow

Since 2f569af (CONFIG_HIGHPTE vs. sub-page page tables.) pte_free() calls
pte_lock_deinit() and dec_zone_page_state(). So free_pgd_slow must not call
the latter two when calling the first.

As the procfs export of ATAGS is not meant as a stable, general purpose
ABI it shouldn't be an independent, general configuration option.

from the function init_programmable_clock()
to the function .init.text:at91_css_to_clk()
The function init_programmable_clock() references
the function __init at91_css_to_clk().
This is often because init_programmable_clock lacks a __init
annotation or the annotation of at91_css_to_clk is wrong.
In this case the only calls to and from init_programmable_clock()
are from code marked as "__init", so this fix is trivially correct.
