Subject: [PATCH v2 1/8] KVM: arm64: Rename .idmap.text in hyp linker script
Date:   Tue,  5 Jan 2021 18:05:34 +0000
Message-Id: <20210105180541.65031-2-dbrazdil@google.com>

So far hyp-init.S created a .hyp.idmap.text section directly, without
relying on the hyp linker script to prefix its name. Change it to create
.idmap.text and add a HYP_SECTION entry to hyp.lds.S. This way all .hyp*
sections go through the linker script and can be instrumented there.
