Hello guys,
Greg, please drop this patch set. Rest of this email is FYI only.
Michael:
Are you sure? __mips__ is automagically defined by GCC, if compiling
for MIPS. Maybe it should be converted to some CONFIG_... symbol.
But removal seems wrong.
You are right. The majority of the removed #ifdef __mips__ code has to
do with write flushing. To accomplish this, it performs a R_REG after a
W_REG. I assumed that writeb() and friends guarantee ordering and write
flushing, but after some reading I learned that this is not the case.
I will rework the code and submit a new patch set.
For some background info: this patch was a reaction on an email from
John Linville to us. John wrote:

I took a quick run through a pull of staging from today. I made a few
notes, but a lot of them would seem to relate to the utils stuff you
mention above. One general comment would be that there still seems
to be a lot of MIPS-specific stuff buried in the code, in particular
a lot of "#ifdef __mips__" stuff that if necessary should at least
be hidden inside the W_REG macro.

Thanks, Roland.
