Subject: [PATCH] MIPS: BMIPS: do not change interrupt routing depending on
|
||
|
|
boot CPU
|
||
|
|
|
||
|
|
Commit 4df715aa ("MIPS: BMIPS: support booting from physical CPU other
|
||
|
|
than 0") changed the interupt routing when we are booting from physical
|
||
|
|
CPU 0, but the settings are actually correct if we are booting from
|
||
|
|
physical CPU 0 or CPU 1. Revert that specific change.
