[PATCH] HPT37x: read f_CNT saved by BIOS from port

[PATCH] HPT37x: read f_CNT saved by BIOS from port

The undocumented register BIOS uses for saving f_CNT seems to only be
mapped to I/O space while all the other HPT3xx regs are dual-mapped.  Looks
like another HighPoint's dirty trick.  With this patch, the deadly kernel
oops on the cards having the modern HighPoint BIOSes is now at last gone!
