When should VOL_DIRTY be cleared?
The current behavior is ...
Case of mkdir, rmdir, rename:

- set VOL_CLEAN after operating.
In async mode, it is actually written to the media after 30 seconds.
Case of cp, touch:

ptrace_get_reg() and ptrace_set_reg() are only used internally by
ptrace.
Move them in arch/powerpc/kernel/ptrace/ptrace-decl.h

Instead of calling get_tm_stackpointer() from the caller, call it
directly from get_sigframe(). This avoids a double call and
allows get_tm_stackpointer() to become static and be inlined
into get_sigframe() by GCC.

The logging of bad frame appears half a dozen of times

This series replaces copies to users by unsafe_put_user() and friends
with user_write_access_begin() dance in signal32.
The advantages are:
- No KUAP unlock/lock at every copy
- More readable code.
- Better generated code.
Copying Al Viro who did it on x86 and may have suggestions,
and Dmitry V.
To really be inlined, the functions needs to be defined in the
same C file as the caller, or in an included header.
Move functions from signal .c defined inline in signal.h

Reorder actions in save_user_regs() and save_tm_user_regs() to
regroup copies together in order to switch to user_access_begin()
logic in a later patch.
In save_tm_user_regs(), first perform copies to frame, then
perform copies to tm_frame.

There is no point in copying floating point regs when there
is no FPU and MATH_EMULATION is not selected.
Create a new CONFIG_PPC_FPU_REGS bool that is selected by
CONFIG_MATH_EMULATION and CONFIG_PPC_FPU, and use it to
opt out everything related to fp_state in thread_struct.
The asm const used o
If something is bad in the frame, there is no point in
knowing which part of the frame exactly is wrong as it
got allocated as a single block.
Always print the root address of the frame in case on
failed user access, just like handle_signal32().

Implement 'unsafe' version of put_compat_sigset()
For the bigendian, use unsafe_put_user() directly
to avoid intermediate copy through the stack.
For the littleendian, use a straight unsafe_copy_to_user().
