Subject: [PATCH v3 01/21] KVM: arm64: Introduce template for inline functions
Date: Fri,  7 May 2021 16:31:04 +0800	[thread overview]
Message-ID: <20210507083124.43347-2-gshan@redhat.com> (raw)
In-Reply-To: <20210507083124.43347-1-gshan@redhat.com>

The inline functions used to get the SMCCC parameters have same
layout. It means the logical functionality can be presented by
a template, to make the code simplified. Besides, this adds more
similar inline functions like smccc_get_arg{4,5,6,7,8}() to visit
more SMCCC arguments, which are required by SDEI virtualization
support.
