Subject: [PATCH] bsd-user: Specify host page alignment if none specified
Date: Thu, 27 Jul 2023 21:54:56 -0600	[thread overview]
Message-ID: <20230728035456.99066-1-imp@bsdimp.com> (raw)

We're hitting an assert when we pass in alignment == 0 since that's not
a power of two. so pass in the ideal page size.
