----------------------------------------------------------------
RISC-V Patches for the 6.1 Merge Window, Part 2

* A handful of DT updates for the PolarFire SOC.
* A fix to correct the handling of write-only mappings.
* m{vetndor,arcd,imp}id is now in /proc/cpuinfo
* The SiFive L2 cache controller support has been refactored to also
  support L3 caches.

There's also a handful of fixes, cleanups and improvements throughout
the tree.

----------------------------------------------------------------
We still have these kasan/pcpu_alloc panics, but by all appearances the bug has
been around for a while so it's not the fault of any of these (even if it just
started manifesting very often for me in the middle of the merge window).  I've
got that and a build fix for drm/amd/display in my test trees, but otherwise
things seem clean on my end.

I've got one merge conflict with a master from last night, just a pair of
cleanups that happened to run into each other.  Here's my resolution if it
helps any:

+++ b/arch/riscv/kernel/vdso.c
@@@ -119,18 -114,16 +119,19 @@@ int vdso_join_timens(struct task_struc
  {
        struct mm_struct *mm = task->mm;
        struct vm_area_struct *vma;

 -      struct __vdso_info *vdso_info = mm->context.vdso_info;

        mmap_read_lock(mm);

-       for (vma = mm->mmap; vma; vma = vma->vm_next) {
+       for_each_vma(vmi, vma) {
                unsigned long size = vma->vm_end - vma->vm_start;

 -              if (vma_is_special_mapping(vma, vdso_info->dm))
 +              if (vma_is_special_mapping(vma, vdso_info.dm))
                        zap_page_range(vma, vma->vm_start, size);
 +#ifdef CONFIG_COMPAT
 +              if (vma_is_special_mapping(vma, compat_vdso_info.dm))
 +                      zap_page_range(vma, vma->vm_start, size);
 +#endif
        }

        mmap_read_unlock(mm);

Sorry it's another big one late in the merge window, I'm trying to not do that
but things keep slipping.
