Subject: [PATCH 2/3] memblock tests: fix undefined reference to `panic'
Date: Tue,  2 Apr 2024 13:27:00 +0000
Message-Id: <20240402132701.29744-3-richard.weiyang@gmail.com>
In-Reply-To: <20240402132701.29744-1-richard.weiyang@gmail.com>
References: <20240402132701.29744-1-richard.weiyang@gmail.com>
Precedence: bulk

commit e96c6b8f212a ("memblock: report failures when memblock_can_resize
is not set") introduced the usage of panic, which is not defined in
memblock test.

Let's define it directly in panic.h to fix it.
