Subject: [PATCH RESEND 1/3] x86/setup: Fix logged allocation range in relocate_initrd()
Date: Wed, 11 Nov 2026 17:56:08 +0100	[thread overview]
Message-ID: <20261111165608.78688-4-blum@kernel.org> (raw)

Since commit c967da6a0ba8 ("x86: Make sure free_init_pages() frees pages
on page boundary"), relocate_initrd() allocates area_size bytes, which
is ramdisk_size rounded up to a page boundary. However, the log still
uses the potentially smaller ramdisk_size to calculate the end of the
allocated range and can report it as too short.

Use area_size instead.

Fixes: c967da6a0ba8 ("x86: Make sure free_init_pages() frees pages on page boundary")
