Anthony Liguori c227f0995e Revert "Get rid of _t suffix"
In the very least, a change like this requires discussion on the list.

The naming convention is goofy and it causes a massive merge problem.  Something
like this _must_ be presented on the list first so people can provide input
and cope with it.

This reverts commit 99a0949b72.

Nathan Froyd 0b5c1ce846 cleanup cpu-exec.c, part 0/N: consolidate handle_cpu_signal
handle_cpu_signal is very nearly copy-paste code for each target, with a
few minor variations.  This patch sets up appropriate defaults for a
generic handle_cpu_signal and provides overrides for particular targets
that did things differently.  Fixing things like the persistent (XXX:
use sigsetjmp) should now become somewhat easier.

Previous comments on this patch suggest that the "activate soft MMU for
this block" comments refer to defunct functionality.  I have removed
such blocks for the appropriate targets in this patch.

Igor Kovalenko 8194f35a0c Sparc64: replace tsptr with helper routine
tl and tsptr of members sparc64 cpu state must be changed
simultaneously to keep trap state window in sync with current
trap level. Currently translation of store to tl does not change
tsptr, which leads to corrupt trap state on corresponding
trap level.

This patch removes tsptr from sparc64 cpu state and replaces
all uses with call to helper routine.

Changes v0->v1:
- reimplemented helper routine with tcg generator
- on cpu reset trap type and pstate are populated with power-on reset
values, including tl=maxtl

Igor Kovalenko f707726e8d sparc64 really implement itlb/dtlb automatic replacement writes
- implement "used" bit in tlb translation entry
- mark tlb entry used if qemu code/data translation succeeds
- fold i/d mmu replacement writes code into replace_tlb_1bit_lru which
adds 1bit lru replacement algorithm; previously code tried to replace
first unlocked entry only

- extract more bitmasks to named macros
- add "immu" or "dmmu" type name to debugging output where appropriate

Igor Kovalenko 6e8e7d4c09 sparc64 name mmu registers and general cleanup
- add names to mmu registers, this helps understanding the code which
uses/modifies them.
- fold i/d mmu tlb entries tag and tte arrays into arrays of tlb entries
- extract demap_tlb routine (code duplication)
- extract replace_tlb routine (code duplication)

- flush qemu tlb translations when replacing sparc64 mmu tlb entries

I have no test case which demands flushing qemu translations,
and this patch should have no other visible changes to runtime.

I now excluded timer interrupt related part.
To my mind other changes are essentially tied together.

Fixed, please find attached the updated version.

Paul Brook 1ad2134f91 Hardware convenience library
The only target dependency for most hardware is sizeof(target_phys_addr_t).
Build these files into a convenience library, and use that instead of
building for every target.

Remove and poison various target specific macros to avoid bogus target
dependencies creeping back in.

Big/Little endian is not handled because devices should not know or care
about this to start with.

aliguori 6b9175478e Refactor translation block CPU state handling (Jan Kiszka)
This patch refactors the way the CPU state is handled that is associated
with a TB. The basic motivation is to move more arch specific code out
of generic files. Specifically the long #ifdef clutter in tb_find_fast()
has to be overcome in order to avoid duplicating it for the gdb
watchpoint fixes (patch "Restore pc on watchpoint hits").
