|
|
|
+Subject: [PATCH V2 03/13] MIPS: BMIPS: change compile time checks to runtime
|
|
|
checks
|
|
|
|
|
|
Allow building for all bmips cpus at the same time by changing ifdefs
|
|
|
to checks for the cpu type, or adding appropriate checks to the
|
|
|
assembly.
|
|
|
|
|
|
+Since BMIPS43XX and BMIPS5000 require different IPI implementations,
|
|
|
+split the SMP ops into one for each, so the runtime overhead is only
|
|
|
+at registration time for them.
|
|
