microblaze: Update elf machine nums.

189 was allocated in upstream binutils.

0xbaab was the old temporary value. Still used by some tools and the
linux kernel.

I've seen 115 in older gdb versions, but lets ignore that one.

linux-user: rlimit conversion between host and target.

rlim_t conversion between host and target added.
Otherwise there are some incorrect case like
- RLIM_INFINITY on 32bit target > 64bit host.
 RLIM_INFINITY on 64bit host > mips and sparc target ?
 Big value(for 32bit target) on 64bit host -> 32bit target....

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....

Remove PAGE_RESERVED

The usermode PAGE_RESERVED code is not required by the current mmap
implementation, and is already broken when guest_base != 0.
Unfortunately the bsd emulation still uses the old mmap implementation,
so we can't rip it out altogether....

Better default guest_base

Avoid loading linux-user applications in address space already used/reserved
by the host.

target-alpha: Implement rs/rc properly.

This is a per-cpu flag; there's no need for a spinlock of any kind.

We were also failing to manipulate the flag with $31 as a target reg
and failing to clear the flag on execution of a return-from-interrupt
instruction....

target-alpha: Fix load-locked/store-conditional.

Use an exception plus start_exclusive to implement the compare-and-swap.
This follows the example set by the MIPS and PPC ports.

linux-user: Fix sparc32plus stat64 syscalls.

Check TARGET_ABI_BITS, not TARGET_LONG_BITS, when deciding
whether or not the guest needs special 64-bit stat translation.

linux-user: Remove ELFLOAD32.

The ABI-specific types used by linux_binprm and image_info
are different after forcing TARGET_ABI32 on. Which means
that the parameters that load_elf_binary_multi sees are not
those that loader_exec passed. This is inherently broken...
