While i386, x86_64 and Sparc64/OpenBSD still worked after
df70204db5, Sparc32 and Sparc64 Linux hosts
broke.

Partially revert the commit: make the restored code conditional to
!CONFIG_USER_PIE.

df70204db5 Fix text relocations in linux-user targets 
There is a link hack in linux-user which produces an executable that
looks like PIE, but always has text relocations since all object files
isn't position-independent (compiled without -fpic/-fpie). Dynamic loader
has to do more work to load a binary with text relocations.

The best way to keep this functionality is to build a true PIE without
text relocations.

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

fd4d81dd04 linux-user: increment MAX_ARG_PAGES 
There's a error When doing something like that :
find / -type f -print0 | xargs -0 echo

[ done in a arm chroot with qemu-arm and linux binfmt stuff or with
find / -type f -print0 | qemu-arm -L <path> <path>/usr/bin/xargs -0
echo ]

Doing this outsite qemu is fine. The problem was the huge number of
parameters. Increasing MAX_ARG_PAGES is fixing that.

While I was at it, I've modified linux-user/main.c to report error code
of loader_exec. It helps to debug/know what's wrong.

0b1bcb00fb MIPS signal handling fixes. 
Also fixes a register corruption bug in do_sigreturn. When "returning"
from sigreturn we are actually restoring the virtual cpu state from the
signal frame.  This is actually surprisingly hard to observe in practice.

Typically an thread be blocked in a FUTEX_WAIT call when the signal arrives,
so the effect is a spurious syscall success and the introduction of a
subtle race condition.

On x86/arm a syscall modifies a single word sized register, so
do_sigreturn can just return that value.  On MIPS a syscall clobbers
multiple registers, so we need additional smarts.  My solution is to
invent a magic errno value that means "don't touch CPU state".

e1833e1f96 Rework PowerPC exceptions model to make it more versatile: 
* don't use exception vectors as the exception number.
  Use vectors numbers as defined in the PowerPC embedded specification instead
  and extend this model to cover all emulated PowerPC variants exceptions.
* add some missing exceptions definitions, from PowerPC 2.04 specification
  and actual PowerPC implementations.
* add code provision for hypervisor exceptions handling.
* define exception vectors and prefix in CPUPPCState to emulate BookE exception
  vectors without any hacks.
* define per CPU model valid exception vectors.
* handle all known exceptions in user-mode only emulations.
* fix hardware interrupts priorities in most cases.
* change RET_EXCP macros name into GEN_EXCP as they don't return.
* do not stop translation on most instructions that are not defined as
  context-synchronizing in PowerPC specification.
* fix PowerPC 64 jump targets and link register update when in 32 bits mode.
* Fix PowerPC 464 and 464F definitions.

76a66253e5 Great PowerPC emulation code resynchronisation and improvments: 
- Add status file to make regression tracking easier
- Move all micro-operations helpers definitions into a separate header:
  should never be seen outside of op.c
- Update copyrights
- Add new / missing PowerPC CPU definitions
- Add definitions for PowerPC BookE
- Add support for PowerPC 6xx/7xx software driven TLBs
  Allow use of PowerPC 603 as an example
- Add preliminary code for POWER, POWER2, PowerPC 403, 405, 440, 601, 602
  and BookE support
- Avoid compiling priviledged only resources support for user-mode emulation
- Remove unused helpers / micro-ops / dead code
- Add instructions usage statistics dump: useful to figure which instructions
  need strong optimizations.
- Micro-operation fixes:
  * add missing RETURN in some micro-ops
  * fix prototypes
  * use softfloat routines for all floating-point operations
  * fix tlbie instruction
  * move some huge micro-operations into helpers
- emulation fixes:
  * fix inverted opcodes for fcmpo / fcmpu
  * condition register update is always to be done after the whole
    instruction has completed
  * add missing NIP updates when calling helpers that may generate an
    exception
- optimizations and improvments:
  * optimize very often used instructions (li, mr, rlwixx...)
  * remove specific micro-ops for rarely used instructions
  * add routines for addresses computations to avoid bugs due to multiple
    different implementations
  * fix TB linking: do not reset T0 at the end of every TB.
