I have my doubts

#ifdef PAGE_KERNEL_NOCACHE
                            vmap(pages, n_pages, VM_MAP, PAGE_KERNEL_NOCACHE);
#else
                            vmap(pages, n_pages, VM_MAP, PAGE_KERNEL);
#endif

is the right "fix" for this...

BTW, PAGE_KERNEL_NOCACHE is defined on frv, m32r, mn10300, sh, and x86 only.

Strangely, both sparc and tile have

/*
 * Some hardware wants to get fixmapped without caching.
 */
#define set_fixmap_nocache(idx, phys) \
                __set_fixmap(idx, phys, PAGE_KERNEL_NOCACHE)

in their <asm/fixmap.h>, without having PAGE_KERNEL_NOCACHE...
