Subject: [kvm-unit-tests PATCH v2 2/7] riscv: setup: Apply VA_BASE check to rv64
Date: Mon, 12 Aug 2024 15:44:54 +0200	[thread overview]
Message-ID: <20240812134451.112498-11-andrew.jones@linux.dev> (raw)
In-Reply-To: <20240812134451.112498-9-andrew.jones@linux.dev>

The VA_BASE check in setup() also applies to rv64, as is clear from
the later VA_BASE check in mem_allocator_init(), which ensures
freemem_start < freemem_end < VA_BASE.

Fixes: 6895ce6dc618 ("riscv: Populate memregions and switch to page allocator")
Signed-off-by: Andrew Jones <andrew.jones@linux.dev>
