Subject: [PATCH 0/8] powerpc: improve copy_thread
Date: Wed, 1 Feb 2023 02:55:26 +1000 [thread overview]
Message-ID: <20230131165534.601490-1-npiggin@gmail.com> (raw)
The way copy_thread works, particularly with kernel threads and kernel
created user threads is a bit muddled and confusing. This series tries
to straighten things out a bit.
Thanks,
Nick
Nicholas Piggin (8):
powerpc: copy_thread remove unused pkey code
powerpc: copy_thread make ret_from_fork register setup consistent
powerpc: use switch frame for ret_from_kernel_thread parameters
powerpc/64: ret_from_fork avoid restoring regs twice
powerpc: copy_thread differentiate kthreads and user mode threads
powerpc: differentiate kthread from user kernel thread start
powerpc: copy_thread don't set _TIF_RESTOREALL
powerpc: copy_thread don't set ppr in user interrupt frame regs
