9ea8b7c96f [POWERPC] Virtual DMA support for floppy driver for new powerpc architecture
During ppc64+ppc merge virtual DMA code for floppy driver was not
ported.  This patch restores virtual DMA support for floppy in new
powerpc target.

It is necessary at least on Pegasos and AmigaOne machines for the
floppy drive to function.  ISA DMA controller works incorrectly there
due to its addressing limitations.

Virtual DMA mode is activated by floppy=nodma option passed to the
kernel (or module).  There's no automatic switch like on i386.

afedfd016a [PATCH] random: remove SA_SAMPLE_RANDOM from floppy driver
The floppy driver is already calling add_disk_randomness as it should, so this
was redundant.

b239cbe957 [PATCH] powerpc: make ISA floppies work again
We used to assume that a DMA mapping request with a NULL dev was for
ISA DMA.  This assumption was broken at some point.  Now we explicitly
pass the detected ISA PCI device in the floppy setup.

88ced03149 [PATCH] powerpc: sanitize header files for user space includes
include/asm-ppc/ had #ifdef __KERNEL__ in all header files that
are not meant for use by user space, include/asm-powerpc does
not have this yet.

This patch gets us a lot closer there. There are a few cases
where I was not sure, so I left them out. I have verified
that no CONFIG_* symbols are used outside of __KERNEL__
any more and that there are no obvious compile errors when
including any of the headers in user space libraries.

... and also delete some that are no longer used because we already
had an include/asm-powerpc version of the header.
