Linus Torvalds 527d151131 Merge branch 'next' of git://git.kernel.org/pub/scm/linux/kernel/git/benh/powerpc
Pull powerpc LE updates from Ben Herrenschmidt:
 "With my previous pull request I mentioned some remaining Little Endian
  patches, notably support for our new ABI, which I was sitting on
  making sure it was all finalized.

  The toolchain folks confirmed it now, the new ABI is stable and merged
  with gcc, so we are all good.  Oh and we actually missed the actual
  Kconfig switch for LE so here it is, along with a couple more bug
  fixes.

  I have more fixes but not related to LE so I'll send them as a
  separate pull request tomorrow, let's get this one out of the way.

  Note that this supports running user space binaries using the new ABI,
  but the kernel itself still needs to be built with the old one.  We'll
  bring fixes for that after -rc1.

  Here's Anton log that goes with this series:

     This patch series adds support for the new ABI, LPAR support for
     H_SET_MODE and finally adds a kconfig option and defconfig.

     ABIv2 support was recently committed to binutils and gcc, and should
     be merged into glibc soon.  There are a number of very nice
     improvements including the removal of function descriptors.  Rusty's
     kernel patches allow binaries of either ABI to work, easing the
     transition"

Ulrich Weigand 280270828f powerpc: Wrong DWARF CFI in the kernel vdso for little-endian / ELFv2
I've finally tracked down why my CR signal-unwind test case still
fails on little-endian.  The problem turned to be that the kernel
installs a signal trampoline in the vDSO, and provides a DWARF CFI
record for that trampoline.  This CFI describes the save location
for CR:

  rsave (70, 38*RSIZE + (RSIZE - CRSIZE))

which is correct for big-endian, but points to the wrong word on
little-endian.   This is wrong no matter which ABI.

In addition, for the ELFv2 ABI, we should not only provide a CFI
record for register 70 (cr2), but for all CR fields separately.
Strictly speaking, I guess this would mean providing two separate
vDSO images, one for ELFv1 processes and one for ELFv2 processes (or
maybe playing some tricks with conditional DWARF expressions).
However, having CFI records for the other CR fields in ELFv1 is not
actually wrong, they just will be ignored.   So it seems the simplest
fix would be just to always provide CFI for all the fields.

Rusty Russell 373c76d622 powerpc: Add TIF_ELF2ABI flag.
Little endian ppc64 is getting an exciting new ABI.  This is reflected
by the bottom two bits of e_flags in the ELF header:

	0 == legacy binaries (v1 ABI)
	1 == binaries using the old ABI (compiled with a new toolchain)
	2 == binaries using the new ABI.

We store this in a thread flag, because we need to set it in core
dumps and for signal delivery.  Our chief concern is that it doesn't
use function descriptors.

Andreas Bießmann d617b338bb avr32: fix out-of-range jump in large kernels
This patch fixes following error (for big kernels):

---8<---
arch/avr32/boot/u-boot/head.o: In function `no_tag_table':
(.init.text+0x44): relocation truncated to fit: R_AVR32_22H_PCREL against symbol `panic' defined in .text.unlikely section in kernel/built-in.o
arch/avr32/kernel/built-in.o: In function `bad_return':
(.ex.text+0x236): relocation truncated to fit: R_AVR32_22H_PCREL against symbol `panic' defined in .text.unlikely section in kernel/built-in.o
--->8---

It comes up when the kernel increases and 'panic()' is too far away to fit in
the +/- 2MiB range. Which in turn issues from the 21-bit displacement in
'br{cond4}' mnemonic which is one of the two ways to do jumps (rjmp has just
10-bit displacement and therefore a way smaller range). This fact was stated
before in 8d29b7b9f8.
One solution to solve this is to add a local storage for the symbol address
and just load the $pc with that value.

timer when the Watchdog mode is enabled.

watchdog occur when TIMER watchdog counter matches the value software

Ramkumar Ramachandra e40f04d040 arch/um: make it work with defconfig and x86_64
arch/um/defconfig only lists one default configuration, and that applies
only to the i386 architecture.  Replace it with two minimal
configuration files generated using `make savedefconfig`:

  i386_defconfig and x86_64_defconfig

The build scripts now require two updates:

1. um's Kconfig (arch/x86/um/Kconfig) should specify an ARCH_DEFCONFIG
   section explicitly pointing to these scripts if the required
   variables are set.  Take care to remove the DEFCONFIG_LIST section
   defined in the included file arch/um/Kconfig.common.

2. um's Makefile (arch/um/Makefile) should set KBUILD_DEFCONFIG properly
   for the top-level Makefile to pick up.  Copy the logic in
   arch/x86/Makefile to properly pick the defconfig file depending on
   the actual architecture; except we're working with $SUBARCH here,
   instead of $ARCH.

Now, you can do:

  $ ARCH=um make defconfig
  $ ARCH=um make

and successfully build User-Mode Linux on an x86_64 box in default
configuration.

Richard Weinberger a1850e9c72 um: Get rid of thread_struct->saved_task
As we have a sane show_stack() now, we can drop
the ->saved_task hack.

Richard Weinberger f72c22e45e um: Make stack trace reliable against kernel mode faults
As UML uses an alternative signal stack we cannot use
the current stack pointer for stack dumping if UML itself
dies by SIGSEGV. To bypass this issue we save regs taken
from mcontext in our segv handler into thread_struct and
use these regs to obtain the stack pointer in show_stack().

Richard Weinberger 9d1ee8ce92 um: Rewrite show_stack()
Currently on UML stack traces are not very reliable and both
x86 and x86_64 have their on implementations.
This patch unifies both and adds support to outline unreliable
functions calls.
