Subject: [PATCH 0/4] Remove WARN_ON in save_processor_state
Date: Thu, 25 May 2023 10:55:51 +0800 [thread overview]
Message-ID: <20230525025555.24104-1-songshuaishuai@tinylab.org> (raw)
During hibernation or restoration, freeze_secondary_cpus
checks num_online_cpus via BUG_ON, and the subsequent
save_processor_state also does the checking with WARN_ON.
So remove the unnecessary checking in save_processor_state
for ARM,arm64,riscv,xtensa architechtures.
Song Shuai (4):
ARM: hibernate: remove WARN_ON in save_processor_state
arm64: hibernate: remove WARN_ON in save_processor_state
riscv: hibernate: remove WARN_ON in save_processor_state
xtensa: hibernate: remove WARN_ON in save_processor_state
