I posted the following two patches for supporting microblaze and unicore32. 

[PATCH v2 1/2] io: prevent compiler reordering on the default writeX() 
[PATCH v2 2/2] io: prevent compiler reordering on the default readX() 

The rest of the arches except mips and alpha seem OK.
I sent a question email on Friday to mips and alpha mailing lists. I'll follow

an actual patch today.
