Subject: [PATCH v5 0/3] x86/boot: Introduce the kernel_info et consortes
Date: Mon,  4 Nov 2019 16:13:51 +0100	[thread overview]
Message-ID: <20191104151354.28145-1-daniel.kiper@oracle.com> (raw)

Hi,

Due to very limited space in the setup_header this patch series introduces new
kernel_info struct which will be used to convey information from the kernel to
the bootloader. This way the boot protocol can be extended regardless of the
setup_header limitations. Additionally, the patch series introduces some
convenience features like the setup_indirect struct and the
kernel_info.setup_type_max field.

Daniel
