4137b31566 avr32/at32ap: fix mapping of platform device id for USART
This patch will fix the mapping of the platform device id when mapping USART
peripheral ID to UART platform device id. Not setting the platform device id
will in most cases (when you map USART > 0 to UART 0) make the console not
available.

e2a53b7c5b ARM: mach-shmobile: Mackerel USB platform data update
This patch updates the board specific USB support
code for the sh7372 Mackerel board.

With this patch applied port CN22 is driven by the
recently added renesas_usbhs driver using the first
USB controller included in sh7372 aka USBHS0.

Hotplugging of USBHS0 unfortunately has to be
handled by software polling. The sh7372 SoC itself
obviously supports hotplug notification by IRQ but
on the Mackerel board this IRQ happens to be used
for the touch screen.

Also fix the pinmux configuration to avoid setting
up unused pins and fix minor spelling errors.

734c3ce3bd m68k: use kernel processor defines for conditional optimizations
Older m68k-linux compilers will include pre-defined symbols that
confuse what processor it is being targeted for. For example gcc-4.1.2
will pre-define __mc68020__ even if you specify the target processor
as -m68000 on the gcc command line. Newer versions of gcc have this
corrected.

In a few places the m68k code uses defined(__mc68020__) for optimizations
that include instructions that are specific to the CPU 68020 and above.
When compiling with older compilers this will be true even when we have
selected to compile for the older 68000 processors.

Switch to using the kernel processor defines, CONFIG_M68020 and friends.

6235672598 m68knommu: create config options for CPU classes
There are 3 families of CPU core types that we support in the m68knommu
architecture branch. They are

. traditional 68000
. CPU32 (a 68020 core derivative without MMU or bitfield instructions)
. ColdFire

It will be useful going forward to have a CONFIG_ option defined for
each type. We already have one for ColdFire (CONFIG_COLDFIRE), so add
for the other 2 families, CONFIG_M68000 and CONFIG_MCPU32.

2cf9530420e446bb61f665d02afeb81070106900 ("sparc32,leon:

This patch reintroduces the code at the same place it was
removed from. IRQ12 - IRQ14 will crash on LEON SMP without
this patch because it will run the SUN4M IRQ trap handler.

dac853ae89 exec: delay address limit change until point of no return
Unconditionally changing the address limit to USER_DS and not restoring
it to its old value in the error path is wrong because it prevents us
using kernel memory on repeated calls to this function.  This, in fact,
breaks the fallback of hard coded paths to the init program from being
ever successful if the first candidate fails to load.

With this patch applied switching to USER_DS is delayed until the point
of no return is reached which makes it possible to have a multi-arch
rootfs with one arch specific init binary for each of the (hard coded)
probed paths.

Since the address limit is already set to USER_DS when start_thread()
will be invoked, this redundancy can be safely removed.

a91d92875e xen: partially revert "xen: set max_pfn_mapped to the last pfn mapped"
We only need to set max_pfn_mapped to the last pfn mapped on x86_64 to
make sure that cleanup_highmap doesn't remove important mappings at
_end.

We don't need to do this on x86_32 because cleanup_highmap is not called
on x86_32. Besides lowering max_pfn_mapped on x86_32 has the unwanted
side effect of limiting the amount of memory available for the 1:1
kernel pagetable allocation.

This patch reverts the x86_32 part of the original patch.

Will Deacon reports that:

 In 52af9c6c ("ARM: 6943/1: mm: use TTBR1 instead of reserved context ID")
 I updated the ASID rollover code to use only the kernel page tables
 whilst updating the ASID.

 Unfortunately, the code to restore the user page tables was part of a
 later patch which isn't yet in mainline, so this leaves the code
 quite broken.

We're also in the process of eliminating __ARCH_WANT_INTERRUPTS_ON_CTXSW
from ARM, so lets revert these until we can properly sort out what we're
doing with the context switching.

 I updated the ASID rollover code to use only the kernel page tables
 whilst updating the ASID.

 Unfortunately, the code to restore the user page tables was part of a
 later patch which isn't yet in mainline, so this leaves the code
 quite broken.

We're also in the process of eliminating __ARCH_WANT_INTERRUPTS_ON_CTXSW
from ARM, so lets revert these until we can properly sort out what we're
doing with the ARM context switching.

978b42e6f6 unicore32: add KBUILD_DEFCONFIG with unicore32_defconfig (old debug_defconfig)
Rename debug_defconfig to unicore32_defconfig, which is a minimal config for
PKUnity-v3 (130nm) SoC board.
Also, add KBUILD_DEFCONFIG to use 'make defconfig'.

f4728fd21f unicore32: change zImage physical address, though it's PIC codes
U-boot will load the kernel image to 48M physical memory address.
The patch changes it to the correct address, though it's PIC codes.

The patch moves rtc driver for PKUnity-v3 SoC from arch/unicore32/kernel/
to drivers/rtc/, with renaming it to rtc-puv3.c.
Also, Kconfig, Makefile, and MAINTAINERS are modified correspondingly.

307cfe7153 powerpc: Force page alignment for initrd reserved memory
When using 64K pages with a separate cpio rootfs, U-Boot will align
the rootfs on a 4K page boundary. When the memory is reserved, and
subsequent early memblock_alloc is called, it will allocate memory
between the 64K page alignment and reserved memory. When the reserved
memory is subsequently freed, it is done so by pages, causing the
early memblock_alloc requests to be re-used, which in my case, caused
the device-tree to be clobbered.

This patch forces the reserved memory for initrd to be kernel page
aligned, and will move the device tree if it overlaps with the range
extension of initrd. This patch will also consolidate the identical
function free_initrd_mem() from mm/init_32.c, init_64.c to mm/mem.c,
and adds the same range extension when freeing initrd. free_initrd_mem()
is also moved to the __init section.

Many thanks to Milton Miller for his input on this patch.
