Subject: [PATCH 3/6] scripts/gdb: change the layout of vmemmap
Date: Wed, 19 Jun 2024 15:49:08 +0800	[thread overview]
Message-ID: <20240619074911.100434-4-kuan-ying.lee@canonical.com> (raw)
In-Reply-To: <20240619074911.100434-1-kuan-ying.lee@canonical.com>

We need to change the layout of vmemmap in gdb scripts after
commit 32697ff38287 ("arm64: vmemmap: Avoid base2 order of
struct page size to dimension region") changed it.

Fixes: 32697ff38287 ("arm64: vmemmap: Avoid base2 order of struct page size to dimension region")
