UML on i386 has build errors (defconfig):

CC mm/vmalloc.o
../mm/vmalloc.c: In function â__purge_vmap_area_lazyâ:
../mm/vmalloc.c:1286:8: error: âSHARED_KERNEL_PMDâ undeclared (first use in this function); did you mean âPAGE_KERNEL_ROâ?
if (!SHARED_KERNEL_PMD && boot_cpu_has(X86_FEATURE_PTI))
^~~~~~~~~~~~~~~~~
PAGE_KERNEL_RO
../mm/vmalloc.c:1286:8: note: each undeclared identifier is reported only once for each function it appears in
../mm/vmalloc.c:1286:29: error: implicit declaration of function âboot_cpu_hasâ; did you mean âget_cpu_maskâ? [-Werror=implicit-function-declaration]
if (!SHARED_KERNEL_PMD && boot_cpu_has(X86_FEATURE_PTI))
^~~~~~~~~~~~
get_cpu_mask
