ee4ee52727 sparc64: Fix bug in PTRACE_SETFPREGS64 handling.
From: Chris Torek <chris.torek@windriver.com>

>The SPARC64 kernel code for PTRACE_SETFPREGS64 appears to be an exact copy 
>of that for PTRACE_GETFPREGS64.  This means that gdbserver and native 
>64-bit GDB cannot set floating-point registers.

It looks like a simple typo.

2434bbb30e powerpc: Fix dma_map_sg() cache flushing on non coherent platforms
On PowerPC 4xx or other non cache-coherent platforms, we lost the
appropriate cache flushing in dma_map_sg() when merging the 32 and
64-bit DMA code (commit 4fc665b88a79a45bae8bbf3a05563c27c7337c3d,
"powerpc: Merge 32 and 64-bit dma code").  This restores it.

7a0d7940e7 powerpc: Use physical cpu id when setting the processor affinity
In the CONFIG_SMP case the irq_choose_cpu() code was returning back
a logical cpu id not the physical id.  We were writing that directly
into the HW register.

We need to be calling get_hard_smp_processor_id() so irq_choose_cpu()
always returns a physical cpu id.

bc2fd1c09c [ARM] pxa: add basic support for HP iPAQ h5000
This patch adds HP iPAQ h5000's (h5400, h5500) basic definitions.

Kernel will able to boot, work via serial console, mount filesystems
placed on flashes and run USB gadgets (g_ether by default).

Other device drivers (frame buffer, LCD, touchscreen, backlight,
bluetooth, w1/battery, ...) are depend on SAMCOP and MediaQ
SoCs/MFDs, drivers to which will be submitted too, after massive
cleanups.

This machine will be used as "real user" for these new drivers.

This is an updated version of the patch, which contains fixes proposed on
linux-arm-kernel mailing list.

Change the halt and reboot method from gpio based to "jump
to ROM IPL beginning". This gives control back to IPL, which
without PowerOn key pressed, will put the device into deep
sleep until PowerOn is pressed for 1 second.

But this has the benefit of keeping the RTC registers across
reboots, which is good for OS change.

65587f7d15 [ARM] pxa: cpufreq-pxa2xx: allow frequency table selection
Following the removal of the "->policy" usage for PXA255 in patch
459fc208abd1b365fa013c17d433dfb5b4bc1e3a (cpufreq: remove
policy->governor setting in drivers initialization), this patch
introduces an option (called "pxa255_turbo_table") to select either
the "run" or "turbo" frequency table.

It also cures the runtime warning that was printed each time the
frequency was changed.

Got rid of all references to CPUFREQ_POLICY_* for pxa255, and sticked
with the run/turbo thing.

Tested on an Arcom/Eurotech Viper.

067455aa53 [ARM] pxa: add support for additional GPIOs on PXA26x
Original patch from Marek Vasut, the problems with PXA26x are:

1. there are additional 4 GPIOs 86,87,88,89 have their direction bits
   inverted in GPDR2, as well as their alternate function bits being
   '1' for their GPIO functionality in GAFRx

2. there is no easy way to decide if the processor is a pxa26x or a
   pxa250/pxa255 at run-time, so the assumption here is the pxa26x
   will be treated as one of the pxa25x variants, and board code
   should have a better knowledge of the processor it is featured

Introduce pxa26x_init_irq() for the second purpose, and treat the
additional GPIOs > 85 on PXA25x specially.

Kconfig option CONFIG_CPU_PXA26x is introduced to optimize the code
a bit when PXA26x support isn't needed. Board config options have
to select this to enable the support for PXA26x.

__gpio_is_inverted() will be optimized way when CONFIG_CPU_PXA26x
isn't selected.

Also, fix the incorrect GPIO number passed in pxa27x_init_irq().
