Subject: [PATCH v3 2/2] sparc64: remove dead THREAD_SIZE branches for non-8K pages
Date: Sun, 27 Sep 2026 23:29:01 +0200	[thread overview]
Message-ID: <20260927212913.3237082-2-stian@itx.no> (raw)
In-Reply-To: <20260927212913.3237082-1-stian@itx.no>

Commit 15b9350a177b ("sparc64: Only support 4MB huge pages and 8KB
base pages.") made 8K the only base page size, so PAGE_SHIFT is
always 13 here and the else branches have been dead since. Remove
them.

Fixes: 15b9350a177b ("sparc64: Only support 4MB huge pages and 8KB base pages.")
