Subject: [PATCH v2 0/3] TLB flush counters

The RISC-V patch (2/3) is based on Gary's TLB flush patch series

https://patchwork.kernel.org/project/linux-riscv/list/?series=97315

The x86 kconfig fix patch(1/3) can be applied separately.

Changes from v1->v2:
1. Move the arch specific config option to a common one as it touches
   generic code.
2. Introduced another config that architectures can select to enable
   tlbflush option.

Atish Patra (3):
x86: Move DEBUG_TLBFLUSH option.
RISC-V: Enable TLBFLUSH counters for debug kernel.
RISC-V: Update tlb flush counters
