Great. I'll apply my series on top.

Note that it doesn't apply cleanly on merge branch (47279113c5d0), a 
3-way merge is needed:

$ LANG= git am -3 
~/Téléchargements/1-6-powerpc-64e-Remove-unused-IBM-HTW-code.patch
Applying: powerpc/64e: Remove unused IBM HTW code
Applying: powerpc/64e: Split out nohash Book3E 64-bit code
Using index info to reconstruct a base tree...
M	arch/powerpc/mm/nohash/Makefile
.git/rebase-apply/patch:554: trailing whitespace.
			def->shift = 0;	
warning: 1 line adds whitespace errors.
Falling back to patching base and 3-way merge...
