Merge tag 'powerpc-5.19-4' of git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux

Pull powerpc fixes from Michael Ellerman:

 - Fix BPF uapi confusion about the correct type of bpf_user_pt_regs_t.

 - Fix virt_addr_valid() when memory is hotplugged above the boot-time
   high_memory value.

 - Fix a bug in 64-bit Book3E map_kernel_page() which would incorrectly
   allocate a PMD page at PUD level.

 - Fix a couple of minor issues found since we enabled KASAN for 64-bit
   Book3S.

Thanks to Aneesh Kumar K.V, Cédric Le Goater, Christophe Leroy, Kefeng
Wang, Liam Howlett, Nathan Lynch, and Naveen N. Rao.
