Subject: [PATCH 01/26] crypto: x86/sha1 - Rename conflicting symbol

From: Eric Biggers <[email-masked]>
Date: Sat, 12 Jul 2025 16:22:52 -0700

Rename x86's sha1_update() to sha1_update_x86(), since it conflicts with
the upcoming sha1_update() library function.

Note: the affected code will be superseded by later commits that migrate
the arch-optimized SHA-1 code into the library.  This commit simply
keeps the kernel building for the initial introduction of the library.
