467	Use of bit fields in AHCI driver is not clearly justified based on the specs	Jiri Svoboda		"The new AHCI driver (ahci_hw.h) uses C bit fields to describe hardware registers. C bit fields are not portable, as the packing of bit fields into words depends on the processor-specific ABI. For example, for SPARC and x86 this order is reverse (another question, of course, is the byte-endianness of the words we are packing into).

Drivers should work across disparate CPU architectures. I suggest replacing the use of bit fields with bitwise operations, with the help of bitops.h."	defect	new	major		helenos/unspecified	mainline
