Subject: [PATCH] arm64: kexec: Remove duplicate allocation for trans_pgd
Date: Sun,  5 Apr 2026 19:42:31 +0800	[thread overview]
Message-ID: <20260405114231.264761-1-wsw9603@163.com> (raw)

trans_pgd would be allocated in trans_pgd_create_copy(), so remove the
duplicate allocation before calling trans_pgd_create_copy().

Fixes: 3744b5280e67 ("arm64: kexec: install a copy of the linear-map")
