576c2cdc76 sparc32 do_unassigned_access overhaul v2
According to pages 9-31 - 9-34 of "SuperSPARC & MultiCache Controller
User's Manual":

1. "A lower priority fault may not overwrite the
    MFSR status of a higher priority fault."
2. The MFAR is overwritten according to the policy defined for the MFSR
3. The overwrite bit is asserted if the fault status register (MFSR)
   has been written more than once by faults of the same class
4. SuperSPARC will never place instruction fault addresses in the MFAR.

Implementation of points 1-3 allows booting Solaris 2.6 and 2.5.1.

v2: CODING_STYLE fixes

3e6ba50340 Sparc: fix carry flag handling (Solaris bootblk fix)
The page 108 of the SPARC Version 8 Architecture Manual describes
that addcc and addxcc shall compute carry flag the same way.
The page 110 claims the same about subcc and subxcc instructions.
This patch fixes carry computation in corner cases and removes redundant code.
The most visible effect of the patch is enabling Solaris boot when using OBP.

while wrasi implementation sign-extends ASI operand causing

- use lower 8 bits of ASI register in helpers

72cf2d4f0e Fix sys-queue.h conflict for good
Problem: Our file sys-queue.h is a copy of the BSD file, but there are
some additions and it's not entirely compatible. Because of that, there have
been conflicts with system headers on BSD systems. Some hacks have been
introduced in the commits 15cc923584,
f40d753718,
96555a96d7 and
3990d09adf but the fixes were fragile.

Solution: Avoid the conflict entirely by renaming the functions and the
file. Revert the previous hacks.

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.

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

- 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

- fold i/d mmu tlb entries tag and tte arrays into arrays of tlb entries

- flush qemu tlb translations when replacing sparc64 mmu tlb entries

I have no test case which demands flushing qemu translations,

a1d1bb3101 Refactor and enhance break/watchpoint API (Jan Kiszka)
This patch prepares the QEMU cpu_watchpoint/breakpoint API to allow the
succeeding enhancements this series comes with.

First of all, it overcomes MAX_BREAKPOINTS/MAX_WATCHPOINTS by switching
to dynamically allocated data structures that are kept in linked lists.
This also allows to return a stable reference to the related objects,
required for later introduced x86 debug register support.

Breakpoints and watchpoints are stored with their full information set
and an additional flag field that makes them easily extensible for use
beyond pure guest debugging.

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").
