This patchset unifies the integer definitions across all the

the L64 model (all other 64-bit architectures.)

I started hacking on a similar patch just yesterday, but with a slightly
different goal. My intention was to move the headers in a direction
where a new architecture (microblaze being the next one) would no longer
have to care about ABI defining headers at all, but just use the defaults
from a single #include line.

I could deal with x86 by leaving the current asm-x86/types.h in place,
and change all the others so they can use the common one. The only
difference here would be umode_t and dma_addr_t, which are irregularly
defined on a few architectures, but we can assume reasonable defaults, as in


It seems reasonable to implement what you are proposing on top of my changes, IMO.
