Subject: [PATCH 7/8] x86/platform/uv: Check EFI Boot to set reboot type
Date: Tue, 10 Sep 2019 09:46:16 -0500 [thread overview]
Message-ID: <20190910144610.752086970@stormcage.eag.rdlabs.hpecorp.net> (raw)
In-Reply-To: 20190910144609.909602978@stormcage.eag.rdlabs.hpecorp.net
[-- Attachment #1: check-efi-boot --]
[-- Type: text/plain, Size: 1579 bytes --]
Change to checking for EFI Boot type from previous check on if this
is a KDUMP kernel. This allows for KDUMP kernels that can handle
EFI reboots.
