Subject: [PATCH v2 05/12] perf: arm_pmuv3: Include asm/arm_pmuv3.h from linux/perf/arm_pmuv3.h
Date: Wed, 26 Jun 2024 16:32:29 -0600	[thread overview]
Message-ID: <20240626-arm-pmu-3-9-icntr-v2-5-c9784b4f4065@kernel.org> (raw)
In-Reply-To: <20240626-arm-pmu-3-9-icntr-v2-0-c9784b4f4065@kernel.org>

The arm64 asm/arm_pmuv3.h depends on defines from
linux/perf/arm_pmuv3.h. Rather than depend on include order, follow the
usual pattern of "linux" headers including "asm" headers of the same
name.

With this change, the include of linux/kvm_host.h is problematic due to
circular includes:

In file included from ../arch/arm64/include/asm/arm_pmuv3.h:9,
                 from ../include/linux/perf/arm_pmuv3.h:312,
                 from ../include/kvm/arm_pmu.h:11,
                 from ../arch/arm64/include/asm/kvm_host.h:38,
                 from ../arch/arm64/mm/init.c:41:
../include/linux/kvm_host.h:383:30: error: field 'arch' has incomplete type

Switching to asm/kvm_host.h solves the issue.
