When building with a toolchain that is configured to produce 32-bits executable
|
||
|
|
by default, we will produce __lshrti3 in sched_clock() which is never resolved
|
||
|
|
so the kernel fails to link. Unconditionally use the inline assemble version
|
||
|
|
as suggested by David Daney, which works around the issue.
