Subject: [PATCH v2 1/3] Revert "OvmfPkg/QemuKernelLoaderFsDxe: don't expose kernel command line"
Date: Thu, 17 Jun 2021 12:16:58 +0000 [thread overview]
Message-ID: <20210617121700.2883073-2-dovmurik@linux.ibm.com> (raw)
In-Reply-To: <20210617121700.2883073-1-dovmurik@linux.ibm.com>
This reverts commit efc52d67e1573ce174d301b52fa1577d552c8441.
Manually fixed conflicts in:
OvmfPkg/QemuKernelLoaderFsDxe/QemuKernelLoaderFsDxe.c
Note that besides re-exposing the kernel command line as a file in the
synthetic filesystem, we also revert back to AllocatePool instead of
AllocatePages.
