Subject: MIPS: increase MAX_PHYSMEM_BITS on Loongson 3 only
|
|
Bug-Debian: https://bugs.debian.org/764223
|
|
Forwarded: no
|
|
|
|
Commit c4617318 broke Loongson-2 support and maybe even more by increasing
|
|
the value of MAX_PHYSMEM_BITS. At it is currently only needed on
|
|
Loongson-3, define it conditionally.
|
|
|
|
Note: this should be replace by upstream fix when available.
