Subject: [PATCH v4 1/2] MdeModulePkg/XhciDxe: Fix Aligned Page Allocation
Date: Tue, 15 Oct 2019 11:20:46 -0600	[thread overview]
Message-ID: <bd4353a24d6d073b02834284365e384da1a7a3ff.1571159369.git.ashishsingha@nvidia.com> (raw)
In-Reply-To: <cover.1571159369.git.ashishsingha@nvidia.com>

While allocating pages aligned at an alignment higher than
4K, allocate memory taking into consideration the padding
required for that alignment. The calls to free pages takes
care of this already.
