Subject: AVR32: Make PROT_WRITE | PROT_EXEC imply PROT_READ
From: Haavard Skinnemoen <hskinnemoen@xxxxxxxxx>
The AVR32 MMU has three protection bits for allowing unprivileged access,
write access and execute access respectively. There is no way to deny read
access while allowing write or execute access.
make-prot_write-imply-prot_read.patch in mm does basically the same thing
for several other architectures. One important difference is that this
patch makes PROT_EXEC imply PROT_READ as well, but it looks like this is
the case for most other architectures already.
