        src/sys/arch/arm32/arm32: bcopyinout.S fault.c genassym.cf
Log Message:
The ARM has the same copy-on-write bug as the i386 -- the write enable bit in
PTEs is ignored when in kernel mode.  Hack around this just like we do on the
i386, by adding a prepass to copyout() to check for write permission on the
destination pages.
