context_tracking: Take IRQ eqs entrypoints over RCU Bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=2169516 Conflicts: The drivers/cpuidle/cpuidle-riscv-sbi.c hunk is dropped as RISC-V is not a supported arch and the file is not currently present in Centos-Stream-9. commit 6f0e6c1598b1a3d19fc30db86b6e26d6f881b43d Author: Frederic Weisbecker <frederic@kernel.org> Date: Wed, 8 Jun 2022 16:40:26 +0200 context_tracking: Take IRQ eqs entrypoints over RCU The RCU dynticks counter is going to be merged into the context tracking subsystem. Prepare with moving the IRQ extended quiescent states entrypoints to context tracking. For now those are dumb redirection to existing RCU calls.
