Subject: [PATCH] O(1) scheduler: asm offset changed
Date: 20 Jan 2002 19:05:11 -0500 [thread overview]
Message-ID: <1011571512.17096.371.camel@phantasy> (raw)
Ingo's O(1) scheduler moved the location of the processor entry in
task_struct (and also renamed it cpu). The hard coded offsets in
entry.S, however, were not updated.
This patch, against 2.5.3-pre2 + J2, sets the correct offset and renames
processor to cpu.
Note that nothing actually uses these offsets :-) at the moment but code
used to and may again. Most importantly, preempt-kernel does!
Thanks,
Robert Love
