-Subject: [PATCH] MIPS: Fix bounds check virt_addr_valid
-
-The bounds check used the uninitialized variable vaddr, it should use
-the given parameter kaddr instead. When using the uninitialized value
-the compiler assumed it to be 0 and optimized this function to just
-return 0 in all cases.
-
-This should make the function check the range of the given address and
-only do the page map check in case it is in the expected range of
-virtual addresses.
