Now that the cpu_ld/st_* function directly call helper_ret_ld/st, we can
drop the old helper_ld/st functions.
Backports commit b8611499b940b1b4db67aa985e3a844437bcbf00 from qemu
This is set to true when the index is for an instruction fetch
translation.
The core get_page_addr_code() sets it, as do the SOFTMMU_CODE_ACCESS
acessors.
All targets ignore it for now, and all other callers pass "false".
This will allow targets who wish to split the mmu index between
instruction and data accesses to do so. A subsequent patch will
do just that for PowerPC.
Backports commit 97ed5ccdee95f0b98bedc601ff979e368583472c from qemu
To avoid to many #ifdef in target code, provide a tlb_vaddr_to_host for
both user and softmmu modes. In the first case the function always
succeed and just call the g2h function.
Backports commit 2e83c496261c799b0fe6b8e18ac80cdc0a5c97ce from qemu
At 8k per TLB (for 64-bit host or target), 8 or more modes
make the TLBs bigger than 64k, and some RISC TCG backends do
not like that. On the affected hosts, cut the TLB size in
half---there is still a measurable speedup on PPC with the
next patch.
Backports commit 1de29aef17a7d70dbc04a7fe51e18942e3ebe313 from qemu
Support guest CPUs which need 7 MMU index values.
Add a comment about what would be required to raise the limit
further (trivial for 8, TCG backend rework for 9 or more).
