commit b39ab98e2f4728d98973fd1bc531e3c4cbccb21c
Author: Linus Torvalds <torvalds@linux-foundation.org>
Date:   Mon Oct 30 10:09:56 2017 -0700

    Mark 'ioremap_page_range()' as possibly sleeping
    
    It turns out that some drivers seem to think it's ok to remap page
    ranges from within interrupts and even NMI's.  That is definitely not
    the case, since the page table build-up is simply not interrupt-safe.
    
    This showed up in the zero-day robot that reported it for the ACPI APEI
    GHES ("Generic Hardware Error Source") driver.  Normally it had been
    hidden by the fact that no page table operations had been needed because
    the vmalloc area had been set up by other things.
    
    Apparently due to a recent change to the GHEI driver: commit
    77b246b32b2c ("acpi: apei: check for pending errors when probing GHES
    entries") 0day actually caught a case during bootup whenthe ioremap
    called down to page allocation.  But that recent change only showed the
    symptom, it wasn't the root cause of the problem.
    
    Hopefully it is limited to just that one driver.
    
    If you need to access random physical memory, you either need to ioremap
    in process context, or you need to use the FIXMAP facility to set one
    particular fixmap entry to the required mapping - that can be done safely.
