Re: [patch] x86/ldt: make a size variable unsigned

My static checker complains that we put an upper bound on the "size"

the possible ranges of "old_mm->context.ldt->size" from
init_new_context_ldt() so it thinks maybe it could be negative.

Let's make it unsigned to silence the warning and future proof the code
a bit.
