From: Marc Zyngier Date: Wed, 30 Apr 2025 10:59:16 +0000 (+0100) Subject: KVM: arm64: Kill HCRX_HOST_FLAGS X-Git-Tag: v6.15-rc6~1^2~1^2~1 X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=ef296ee98bb19ee2a6dbf76155184c99da0d7c71;p=thirdparty%2Flinux.git KVM: arm64: Kill HCRX_HOST_FLAGS HCRX_HOST_FLAGS, like most of these hardcoded setups, are not a good match for options that can be selectively enabled or disabled. Nothing but the early setup is relying on it now, so kill the macro and move the bag of bits where they belong.
