#     powerpc/64s: Fix build failure when CONFIG_PPC_64S_HASH_MMU is not set
#     
#     The following build failure occurs when CONFIG_PPC_64S_HASH_MMU is not
#     set:
#     
#         arch/powerpc/kernel/setup_64.c: In function ‘setup_per_cpu_areas’:
#         arch/powerpc/kernel/setup_64.c:811:21: error: ‘mmu_linear_psize’ undeclared (first use in this function); did you mean ‘mmu_virtual_psize’?
#           811 |                 if (mmu_linear_psize == MMU_PAGE_4K)
#               |                     ^~~~~~~~~~~~~~~~
#               |                     mmu_virtual_psize
#         arch/powerpc/kernel/setup_64.c:811:21: note: each undeclared identifier is reported only once for each function it appears in
#     
#     Move the declaration of mmu_linear_psize outside of
#     CONFIG_PPC_64S_HASH_MMU ifdef.
#     
#     After the above is fixed, it fails later with the following error:
#     
#         ld: arch/powerpc/kexec/file_load_64.o: in function `.arch_kexec_kernel_image_probe':
#         file_load_64.c:(.text+0x1c1c): undefined reference to `.add_htab_mem_range'
#     
#     Fix that, too, by conditioning add_htab_mem_range() symbol to
#     CONFIG_PPC_64S_HASH_MMU.
#     
#     Fixes: 387e220a2e5e ("powerpc/64s: Move hash MMU support code under CONFIG_PPC_64S_HASH_MMU")
