    Reinstate lost flush_ioremap_region() fix to pxa2xx-flash driver · 355aaffd
    Linus Torvalds authored
    Commit 90833fda ("[ARM] 4554/1: replace
    consistent_sync() with flush_ioremap_region()") introduced a new
    "flush_ioremap_region()" function to be used by the MTD mainstone-flash
    and lubbock-flash drivers to fix a regression from around 2.6.18.
    
    Those drivers were independently merged into a single driver by Todd
    Poynor in commit e644f7d6 ("[MTD] MAPS:
    Merge Lubbock and Mainstone drivers into common PXA2xx driver")
    
    Later, those two commits were merged into the main MTD tree by commit
    b160292c ("Merge Linux 2.6.23") by David
    Woodhouse, but in that merge, the fix to use flush_iomap_region() got
    lost (as it was to files that now no longer existed).
    
    This reinstates the fix in the new driver.
