Subject: [PATCH v2 1/8] KVM: selftests: KVM: selftests: Add macros for fixed counters in processor.h
Date:   Tue, 30 May 2023 21:42:41 +0800

From: Jinrong Liang <cloudliang@tencent.com>

Add macro in processor.h, providing a efficient way to obtain
the number of fixed counters and fixed counters bit mask. The
addition of these macro will simplify the handling of fixed
performance counters, while keeping the code maintainable and
clean.
