Subject: [PATCH] powerpc/mce: log the error for all unrecoverable errors
Date: Mon, 14 Nov 2022 13:26:07 +0530 [thread overview]
Message-ID: <20221114075607.30631-1-ganeshgr@linux.ibm.com> (raw)
machine_check_log_err() is not getting called for all
unrecoverable errors, And we are missing to log the error.
Raise irq work in save_mce_event() for unrecoverable errors,
So that we log the error from MCE event handling block in
timer handler.
