[linux-yocto] [PATCH] powerpc/603: Fix handling of the DIRTY flag
From: Christophe Leroy
commit 415480dce2ef03bb8335deebd2f402f475443ce0 upstream
If a page is already mapped RW without the DIRTY flag, the DIRTY
flag is never set and a TLB store miss exception is taken forever.
This is easily reproduced with the following app:
void main(void)
{
volatile char *ptr = mmap(0, 4096, PROT_READ | PROT_WRITE, MAP_SHARED |
MAP_ANONYMOUS, -1, 0);
*ptr = *ptr;
}
When DIRTY flag is not set, bail out of TLB miss handler and take
a minor page fault which will set the DIRTY flag.
Fixes: f8b58c64eaef ("powerpc/603: let's handle PAGE_DIRTY directly")

This is for v5.2/standard/fsl-mpc8315e-rdb. It fixes potential system hang
without any direct warning or error which has not been observed on qemuppc.
It has not been ported to stable tree.
