[PATCH] pstore/core: drop cmpxchg based updates

I have here a FPGA behind PCIe which exports SRAM which I use for pstore. Now it seems that the FPGA no longer supports cmpxchg based updates and writes back 0xff…ff and returns the same. This leads to crash during crash rendering pstore useless. Since I doubt that there is much benefit from using

[PATCH v2] perf/x86/amd: Make HW_CACHE_REFERENCES and HW_CACHE_MISSES measure L2

While the Intel PMU monitors the LLC when perf enables the HW_CACHE_REFERENCES and HW_CACHE_MISSES events, these events monitor L1 instruction cache fetches (0x0080) and instruction cache misses (0x0081) on the AMD PMU. This is extremely confusing when monitoring the same workload across Intel and
