1c79145f12 linux user: Fix Lesser GPL version number
There is no "version 2" of the "Lesser" General Public License.
It is either "GPL version 2.0" or "Lesser GPL version 2.1".
This patch replaces all occurrences of "Lesser GPL version 2" with
"Lesser GPL version 2.1" in comment section.

2ad983e0f4 linux-user/sparc: Fix cpu_clone_regs_*
We failed to set the secondary return value in %o1
we failed to advance the PC past the syscall,
we failed to adjust regwptr into the new structure,
we stored the stack pointer into the wrong register.

07a6ecf48f linux-user: Introduce cpu_clone_regs_parent
We will need a target-specific hook for adjusting registers
in the parent during clone.  Add an empty inline function for
each target, and invoke it from the proper places.

608999d17c linux-user: Rename cpu_clone_regs to cpu_clone_regs_child
We will need a target-specific hook for adjusting registers
in the parent during clone.  To avoid confusion, rename the
one we have to make it clear it affects the child.

At the same time, pass in the flags from the clone syscall.
We will need them for correct behaviour for Sparc.

083244d320 linux-user/sparc: Use WREG constants in sparc/target_cpu.h
This fixes a naming bug wherein we used "UREG_FP" to access the
stack pointer.  OTOH, the "UREG_FP" constant was also defined
incorrectly such that it *did* reference the stack pointer.

Note that the kernel legitimately uses the name "FP", because it
utilizes the rolled stack window in processing the system call.

55c5063c61 linux-user: Clean up target_cpu.h header guards
These headers all use TARGET_CPU_H as header guard symbol.  Reuse of
the same guard symbol in multiple headers is okay as long as they
cannot be included together.

Since we can avoid guard symbol reuse easily, do so: use guard symbol
$target_TARGET_CPU_H for linux-user/$target/target_cpu.h.

f5147c93d0 linux-user: Enable NPTL for SPARC targets
Provide the missing cpu_set_tls(), and resolve the FIXME in
cpu_clone_regs() by clearing the carry flag for the child.
This allows us to turn on building with NPTL for SPARC.

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.
