Subject: [PATCH v4 2/4] powerpc/ptdump: Remove unused 'page_size' parameter
Date: Thu,  8 Jul 2021 16:49:41 +0000 (UTC)	[thread overview]
Message-ID: <e2f80d052001155251bfe009c360d0c5d9242c6b.1625762906.git.christophe.leroy@csgroup.eu> (raw)
In-Reply-To: <b864a92693ca8413ef0b19f0c12065c212899b6e.1625762905.git.christophe.leroy@csgroup.eu>

note_page_update_state() doesn't use page_size. Remove it.

Could also be removed to note_page() but as a following patch
will remove all current users of note_page(), just leave it as
is for now.
