Amit Daniel Kachhap 1f518196d8 ARM: dts: Add PMIC node entry for Arndale board
Added S5M8767 PMIC DT nodes for Arndale board. Only the used
LDO's/BUCK are defined here. Also the nodes describe the default/reset
state LDO's and no power mangement tuning is implemented. The usage
desription can be found in s5m8767 device tree binding documentation.

Stuart Yoder f9294e989f powerpc: define the conditions where the ePAPR idle hcall can be supported
For 32-bit, CONFIG_EPAPR_PARAVIRT pulls in both epapr_paravirt.c
and epapr_hcalls.c which contains the 32-bit paravirt idle loop.

For 64-bit, the paravirt idle loop is in idle_book3e.S and that
source file is included only if CONFIG_PPC_BOOK3E_64 defined.

This patch makes that dependency for 64-bit explicit.

Fixes these build errors:

arch/powerpc/kernel/built-in.o: In function `restore_pblist_ptr':

Jan Beulich 909b3fdb0d xen-pciback: notify hypervisor about devices intended to be assigned to guests
For MSI-X capable devices the hypervisor wants to write protect the
MSI-X table and PBA, yet it can't assume that resources have been
assigned to their final values at device enumeration time. Thus have
pciback do that notification, as having the device controlled by it is
a prerequisite to assigning the device to guests anyway.

This is the kernel part of hypervisor side commit 4245d33 ("x86/MSI:
add mechanism to fully protect MSI-X table from PV guest accesses") on
the master branch of git://xenbits.xen.org/xen.git.

Vineet Gupta 367f3fcd92 ARC: Fix the typo in event identifier flags used by ptrace
orig_r8_IS_EXCPN and orig_r8_IS_BRKPT were same values due to a
copy/paste error. Although it looks bad and is wrong, it really doesn't
affect gdb working.

orig_r8_IS_BRKPT is the one relevant to debugging (breakpoints), since
it is used to provide EFA vs. ERET to a ptrace "stop_pc" request.

So when gdb has inserted a breakpoint, orig_r8_IS_BRKPT is already set,
and anything else (i.e. orig_r8_IS_EXCPN) becoming same as it, really
doesn't hurt gdb. The corollary case, could be nasty but nobody uses the
ptrace "stop_pc" request in that case

(e.g.  max_low_pfn) that not only hasn't been setup yet in such early

as uninitialized.

Thus, use __pa_nodebug() rather than __pa_symbol() to get a global
