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.

Doug Kwan d90b94cd78 target-ppc: Support little-endian PPC64 in user mode.
Look at ELF header to determine ABI version on PPC64.  This is required
for executing the first instruction correctly.  Also print correct machine
name in uname() system call.

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.

Peter Maydell 4ce6243dc6 linux-user: Clean up handling of clone() argument order
Linux manages to have three separate orderings of the arguments to
the clone() syscall on different architectures. In the kernel these
are selected via CONFIG_CLONE_BACKWARDS and CONFIG_CLONE_BACKWARDS2.
Clean up our implementation of this to use similar #define names
rather than a TARGET_* ifdef ladder.

This includes behaviour changes fixing bugs on cris, x86-64, m68k,
openrisc and unicore32.  cris had explicit but wrong handling; the
others were just incorrectly using QEMU's default, which happened
to be the equivalent of CONFIG_CLONE_BACKWARDS. (unicore32 appears
to be broken in the mainline kernel in that it tries to use arg3 for
both parent_tidptr and newtls simultaneously -- we don't attempt
to emulate this bug...)

Nathan Froyd bcd4933a23 linux-user: ppc signal handling
Implement setup_{,rt_}frame and do_{,rt_}sigreturn for PPC 32-bit.  Use
the same TARGET_QEMU_ESIGRETURN hack as for MIPS to avoid clobbering
register state on a sigreturn.
