    {x86,powerpc,microblaze}/kmap: move preempt disable · ee9bc5fd
    Ira Weiny authored
    During this kmap() conversion series we must maintain bisect-ability.  To
    do this, kmap_atomic_prot() in x86, powerpc, and microblaze need to remain
    functional.
    
    Create a temporary inline version of kmap_atomic_prot within these
    architectures so we can rework their kmap_atomic() calls and then lift
    kmap_atomic_prot() to the core.
