db5ebe5f41 sparc: Clean up includes
Clean up includes so that osdep.h is included first and headers
which it implies are not included manually.

This commit was created with scripts/clean-includes.

6d5322442a target-sparc: Migrate CWP and PIL for SPARC64
In SPARC32 the env->cwp and env->psrpil state is part of the PSR
register, and gets migrated as part of that register.
In SPARC64 this state is in separate CWP and PIL registers, but we
were not doing anything to migrate those.

Add the missing fields to the migration vmstate (which is a
migration break, but without these fields migration is completely
broken anyway).

This change means that trying a save/load of a SPARC64 target at
the boot rom prompt now produces a system which at least responds
to keyboard input after the restore.

0e88d45a33 target-sparc: Use VMState arrays for SPARC64 TLB/MMU state
Use VMState arrays for SPARC64 TLB/MMU state. This is
a migration-break for SPARC64 (but not for SPARC32),
which is acceptable because currently migration does not
work for any SPARC64 machines due to the lack of any migration
of interrupt controller state.

df32c8d436 target-sparc: Convert to VMStateDescription
Convert the SPARC CPU from cpu_load/save functions to VMStateDescription.
We preserve migration compatibility with the previous version
(required for SPARC32 but not necessarily for SPARC64).

[PMM:
 * Rebase and update to apply to master
 * VMSTATE_STRUCT_POINTER now takes type, not pointer-to-type
 * QEMUTimer* are migrated via VMSTATE_TIMER_PTR
 * Put CPUTimer vmstate struct inside TARGET_SPARC64 ifdef
 * Convert handling of PSR to use a vmstate_psr, like Alpha and ARM

232afac113 target-sparc: Don't flush TLB in cpu_load function
There's no need to flush the TLB in the SPARC cpu_load function: we're
guaranteed to be loading state into a fresh clean configuration.

30038fd818 target-sparc: Change fpr representation to doubles.
This allows a more efficient representation for 64-bit hosts.
It should be about the same for 32-bit hosts, as we can still
access the individual pieces of the double.

5a834bb47c sparc: Fix lazy flag calculation on interrupts, refactor
Recalculate Sparc64 CPU flags on interrupts, otherwise some earlier
flags could be stored to pstate.

Refactor PSR/CCR/CWP handling: concentrate the actual
functions to op_helper.c.

Thanks to Igor Kovalenko for reporting.

8f4efc5588 sparc64: reimplement tick timers v4
sparc64 timer has tick counter which can be set and read,
and tick compare value used as deadline to fire timer interrupt.
The timer is not used as periodic timer, instead deadline
is set each time new timer interrupt is needed.

v3 -> v4:
- coding style

v2 -> v3:
- added missing timer debug output macro
- CPUTimer struct and typedef moved to cpu.h
- change CPU_SAVE_VERSION to 6, older save formats not supported

v1 -> v2:
- new conversion helpers cpu_to_timer_ticks and timer_to_cpu_ticks
- save offset from clock source to implement cpu_tick_set_count
- renamed struct sun4u_timer to CPUTimer
- load and save cpu timers

v0 -> v1:
- coding style

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

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.
