Subject: [PATCH 0/3] KVM: arm64: Keep hyp and host headers separate where possible
Date: Thu, 2 Dec 2021 17:10:45 +0000 [thread overview]
Message-ID: <20211202171048.26924-1-will@kernel.org> (raw)
Hi folks,
This series tidies up the header file usage for the nvhe hyp object so
that header files under arch/arm64/kvm/hyp/include are not included by
host code running at EL1.
For definitions that are shared between the host and hypervisor, these
are either moved to headers under arch/arm64/include/asm/ or are
generated by kbuild along similar lines to asm-offsets.h. For now, this
allows us to tidy up some of the pKVM reserved memory handling, but in
future this will also allow the pKVM EL2 data structures to avoid
polluting the host namespace.
Cheers,
Will
