fault_in_user_writeable() should verify R/W access but only verify W. In most archs W implies R, but not true in MIPS and LoongArch, so fix it.
Yuck for a find_vma() in futex.c. If this is a problem in MIPS, shouldn't the fix be there? Furthermore it's stated that fault_in_user_writeable(): "Fault in user address and verify RW access" And you guys seem to have proposed it already: https://lore.kernel.org/linux-mips/20200630005845.1239974-1-liulichao@xxxxxxxxxxx/ Thanks, Davidlohr
