Tom Musta 6f6a40328b linux-user: Support target-to-host translation of mlockall argument
The argument to the mlockall system call is not necessarily the same on
all platforms and thus may require translation prior to passing to the
host.

For example, PowerPC 64 bit platforms define values for MCL_CURRENT
(0x2000) and MCL_FUTURE (0x4000) which are different from Intel platforms
(0x1 and 0x2, respectively)

Tom Musta 0903c8be9e linux-user: Minimum Sig Handler Stack Size for PPC64 ELF V2
The ELF V2 ABI for PPC64 defines MINSIGSTKSZ as 4096 bytes whereas it was
2048 previously.

Riku Voipio cbc14e6f28 linux-user: set minimum kernel version to 2.6.32
Popular glibc based distributions[1] require minimum
2.6.32 as kernel version. For some targets 2.6.18
would be enough, but dropping so low would mean some
suboptimal system calls could get used.

Set the minimum kernel advertized to 2.6.32 for
all architectures but aarch64 to ensure working qemu
linux-user in case host kernel is older.

Petar Jovanovic 55a2b1631f linux-user: create target_structs header to place ipc_perm and shmid_ds
Creating target_structs header in linux-user/$arch/ and making
target_ipc_perm and target_shmid_ds its first inhabitants.
The struct defintions may/should be further fine-tuned by arch maintainers.

Peter Maydell 6291ad77d7 linux-user: Move cpu_clone_regs() and cpu_set_tls() into linux-user
The functions cpu_clone_regs() and cpu_set_tls() are not purely CPU
related -- they are specific to the TLS ABI for a a particular OS.
Move them into the linux-user/ tree where they belong.

target-lm32 had entirely unused implementations, since it has no
linux-user target; just drop them.

Riku Voipio c3edf3472f linux-user: correct syscall 123 on sh4
As reported by Cédric VINCENT:

The syscall #123 on SH4 should be "TARGET_NR_cacheflush" instead of
"TARGET_NR_modify_ldt" [1].  The only consequence of this misnaming is
that many "Unsupported syscall" warnings are issued when emulating JIT
compilers.

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.
