Hi all,

After merging the arm-perf tree, today's linux-next build (x86_64
allmodconfig) failed like this:

drivers/perf/arm_cspmu/nvidia_cspmu.c: In function 'nv_cspmu_set_ev_filter':
drivers/perf/arm_cspmu/nvidia_cspmu.c:192:9: error: implicit declaration of function 'writel' [-Wimplicit-function-declaration]
192 | writel(filter, cspmu->base0 + offset);
| ^~~~~~

Caused by commit

6de0298a3925 ("perf/arm_cspmu: Generalise event filtering")

I have used the arm-perf tree from next-20250314 for today.
