Subject: Re: [PATCH 00/23] Floppy driver cleanups

Hi Willy,

given that you are actively maintaining the floppy driver now, any
chance I could trick you into proper highmem handling?  I've been trying
to phase out block layer bounce buffering, and any help from a competent
maintainer to move their drivers to properly support highmem by kmapping
for PIO/MMIO I/O would be very helpful.
