Subject: [PATCH 6.12 1100/1102] workqueue: Update documentation as per system_percpu_wq naming

6.12-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Mallesh Koujalagi <mallesh.koujalagi@intel.com>

commit 4a91a33f15c634fb3477d122bdf1eef098d77ee3 upstream.

Update documentation to use "per-CPU workqueue" instead of
"global workqueue" to match the system_wq to system_percpu_wq
rename. The workqueue behavior remains unchanged; this just
aligns terminology with the clearer naming.

Fixes: a2be943b46b4 ("workqueue: replace use of system_wq with system_percpu_wq")
