4de8c75b00 ARM: OMAP: Fix GPIO IRQ unmask
GPIO IRQ unmask doesn't actually do anything useful.  The problem is
hidden by a separate explicit mass unmask at the end of the chained
bank handler.

06cad098d2 ARM: OMAP: Fix clockevent support for hrtimers
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.

72e7ae8141 [ARM] 4823/1: AT91 section fix
Fix section warning:

 WARNING: arch/arm/mach-at91/built-in.o(.text+0xd74): Section mismatch in reference
        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.

86260f9873 [ARM] 4824/1: pxa: clear RDH bit after any reset
According to PXA300/310 and PXA320 Developer manuals,
the ASCR[RDH] "bit needs to be cleared as part of the software
initialization coming out of any reset and coming out of D3".
The latter requirement is addressed by commit
"c4d1fb627ff3072", as for the former (coming out of any reset),
the kernel relies on boot loaders and assumes that RDH bit
is cleared there. Though, not all bootloaders follow the rule
so we have to clear the bit in kernel.

We clear the RDH bit in pxa3xx_init() function since
it is always invoked after any reset. We also preserve D1S, D2S
and D3S bits from being cleared in case we invoke pxa3xx_init()
function not from normal hardware reset (e.g. kexec scenario),
so these bits can be properly referenced later.

ec7748b59e ide: introduce HAVE_IDE
To allow flexible configuration of IDE introduce HAVE_IDE.
All archs except arm, um and s390 unconditionally select it.
For arm the actual configuration determine if IDE is supported.

This is a step towards introducing drivers/Kconfig for arm.
