Clean up slb_lookup() function

The slb_lookup() function, used in the ppc translation path returns a
number of slb entry fields in reference parameters. However, only one
of the two callers of slb_lookup() actually wants this information.

This patch, therefore, makes slb_lookup() return a simple pointer to the...

Parse SDR1 on mtspr instead of at translate time

On ppc machines with hash table MMUs, the special purpose register SDR1
contains both the base address of the encoded size (hashed) page tables.

At present, we interpret the SDR1 value within the address translation...

Use "hash" more consistently in ppc mmu code

Currently, get_segment() has a variable called hash. However it doesn't
(quite) get the hash value for the ppc hashed page table. Instead it
gets the hash shifted - effectively the offset of the hash bucket within...

Clean up PowerPC SLB handling code

Currently the SLB information when emulating a PowerPC 970 is
storeed in a structure with the unhelpfully named fields 'tmp'
and 'tmp64'. While the layout in these fields does match the
description of the SLB in the architecture document, it is not...

Add a hook to allow hypercalls to be emulated on PowerPC

PowerPC and POWER chips since the POWER4 and 970 have a special
hypervisor mode, and a corresponding form of the system call
instruction which traps to the hypervisor.

qemu currently has stub implementations of hypervisor mode. That...

Implement PowerPC slbmfee and slbmfev instructions

For a 64-bit PowerPC target, qemu correctly implements translation
through the segment lookaside buffer. Likewise it supports the
slbmte instruction which is used to load entries into the SLB.

However, it does not emulate the slbmfee and slbmfev instructions...

Implement missing parts of the logic for the POWER PURR

The PURR (Processor Utilization Resource Register) is a register found
on recent POWER CPUs. The guts of implementing it at least enough to
get by are already present in qemu, however some of the helper...

Correct ppc popcntb logic, implement popcntw and popcntd

qemu already includes support for the popcntb instruction introduced
in POWER5 (although it doesn't actually allow you to choose POWER5).

However, the logic is slightly incorrect: it will generate results...
