arch/powerpc/kernel/process.c: In function 'start_thread':
arch/powerpc/kernel/process.c:1104:3: error: implicit declaration of function 'tm_reclaim_current'

Caused by "powerpc/tm: Always reclaim in start_thread() for exec() class syscalls".

This would either require d31626f70b610 ("powerpc: Don't corrupt transactional state
when using FP/VMX in kernel"), which introduces the function, or you could call
tm_reclaim() directly instead (which may be less risky).
