Allthough masked_user_access_begin() is to only be used when reading

and masked_user_write_access_begin() in order to match
user_read_access_begin() and user_write_access_begin().
That means masked_user_read_access_begin() is used when user memory is
exclusively read during the window, masked_user_write_access_begin()
is used when user memory is exclusively writen during the window,
masked_user_access_begin() remains and is used when both reads and
writes are performed during the open window. Each of them is expected
to be terminated by the matching user_read_access_end(),
user_write_access_end() and user_access_end().
Have them default to masked_user_access_begin() when they are
not defined.

Can we please coordinate on that vs. the scoped_access() work as this
nicely collides all over the place?
Sure, I will rebase on top of your series.
Once it is rebased, could you take the non powerpc patches in your tree ?
Thanks
Christophe
