pseries: Fix incorrect calculation of RMA size in certain configurations

For the pseries machine, we need to advertise to the guest the size of its
RMA - that is the amount of memory it can access with the MMU off. For HV
KVM, this is constrained by the hardware limitations on the virtual RMA of...

pseries: Fixes and enhancements to L1 cache properties

PAPR requires that the device tree's CPU nodes have several properties
with information about the L1 cache. We already create two of these
properties, but with incorrect names - "[id]cache-block-size" instead...

PPC: e500: advertise 4.2 MPIC only if KVM supports EPR

Older KVM versions don't support EPR which breaks guests when we announce
MPIC variants that support EPR.

Catch that case and expose only MPIC version 2.0 which tells the guest that
we don't support the EPR capability yet....

PPC: Remove env->hreset_excp_prefix

This value is not needed if we use correctly the MSR[IP] bit.

excp_prefix is always 0x00000000, except when the MSR[IP] bit is
implemented and set to 1, in that case excp_prefix is 0xfff00000.

The handling of MSR[IP] was already implemented but not used at reset...

target-ppc: fix nego and subf*o instructions

The overflow computation of nego and subf*o instructions has been broken
in commit ffe30937. Contrary to other targets, the instruction is subtract
from an not subtract on PowerPC.

This patch fixes the issue by using the correct argument in the xor...

PPC: fix hreset_vector for 60x, 7x0, 7x5, G2, MPC8xx, MPC5xx, 7400 and 7450

According to the different user's manuals, the vector offset for system
reset (both /HRESET and /SRESET) is 0x00100.

This patch may break support of some executables, as the power-on start...

target-ppc: Fix narrow-mode add/sub carry output

Broken in b5a73f8d8a57e940f9bbeb399a9e47897522ee9a, the carry itself was
fixed in 79482e5ab38a05ca8869040b0d8b8f451f16ff62. But we still need to
produce the full 64-bit addition.

Simplify the conditions at the top of the functions for when we need a...

Enable kvm emulated watchdog

Enable the KVM emulated watchdog if KVM supports (use the
capability enablement in watchdog handler). Also watchdog exit
(KVM_EXIT_WATCHDOG) handling is added.
Watchdog state machine is cleared whenever VM state changes to running....

target-ppc: Enable ISEL on POWER7

ISEL is a Power ISA 2.06 instruction and thus is available on POWER7.
Given this is trapped and emulated by the Linux kernel, I guess it went
unnoticed.
