Richard Henderson 05c3ef1451 target/ppc: Remove type argument from mmubooke_check_tlb
We can now use MMU_INST_FETCH from access_type for this.
Unify the I/D code paths, making use of prot_for_access_type.

Richard Henderson 9630cd6262 target/ppc: Use MMUAccessType in mmu_helper.c
This replaces 'int rw' with 'MMUAccessType access_type'.
Comparisons vs zero become either MMU_DATA_LOAD or MMU_DATA_STORE,

Force the exit from the tb via DISAS_TOO_MANY, which allows chaining

Renamed all gen_spr_* and gen_* functions specifically related to
registering SPRs to register_*_sprs and register_*, to avoid future
confusion with other TCG related code.

David Hildenbrand 8f44304c76 numa: Teach ram block notifiers about resizeable ram blocks
Ram block notifiers are currently not aware of resizes. To properly
handle resizes during migration, we want to teach ram block notifiers about
resizeable ram.

Introduce the basic infrastructure but keep using max_size in the
existing notifiers. Supply the max_size when adding and removing ram
blocks. Also, notify on resizes.

If the get_physical_address() call fails, the SH4 get_phys_page_debug()
handler returns an uninitialized address. Instead return -1, which
correspond to "no page found" (see cpu_get_phys_page_debug() doc
string).

This fixes a warning emitted when building with CFLAGS=-O3
