Merge tag 'riscv-mw1-6.15-rc1' of ssh://gitolite.kernel.org/pub/scm/linux/kernel/git/alexghiti/linux into for-next

riscv patches for 6.15-rc1

* A bunch of fixes:
  - We were missing a secondary mmu notifier call when flushing the tlb which is required for IOMMU
  - Fix ftrace panics by saving the registers as expected by ftrace
  - Fix a couple of stimecmp usage related to cpu hotplug
  - Fix a bunch of issues in the misaligned probing handling

* Perf improvements:
  - Introduce support for runtime constant improving perf of d_hash()
  - Add support for huge pfnmaps to improve tlb utilization
  - Use Zawrs to improve smp_cond_load8/16() used by the queued spinlocks

* Hwprobe additions:
  - Add support for Zicntr and Zihpm
  - Add support for Zaamo and Zalrsc
  - Add support for bfloat16 extensiosn
  - Add support for Zicbom (only enabling clean and flush, not inval for security reasons)

* Misc:
  - Add a kernel parameter to bypass the misaligned speed probing since we can't rely on Zicclsm

* tag 'riscv-mw1-6.15-rc1' of ssh://gitolite.kernel.org/pub/scm/linux/kernel/git/alexghiti/linux: (1585 commits)
