Subject: [PATCH 0/2] s390: Remove PIF_GUEST_FAULT and add PER trap flag
Date: Thu, 9 Jul 2026 21:54:58 +0200 [thread overview]
Message-ID: <20260709195500.1241833-1-svens@linux.ibm.com> (raw)
While looking at the syscall code I noticed that entry.S still sets
PIF_GUEST_FAULT in ptregs even though it's only used in __do_pgm_check().
Remove that and pass it directly to __do_pgm_check(). Heiko suggested
to also add a define for the per trap flag in system_call().
Sven Schnelle (2):
s390/traps: Remove PIF_GUEST_FAULT
s390/syscalls: Use define instead of '1' to indicate PER trap
