Although this is a simple instance, could this please be done in a
Kconfig file? If that #define happens inside of other #ifdefs, it can
be quite hard to decipher the special .config incantation to get it set.
On the other hand, if the dependencies are spelled out in a Kconfig
entry...
BTW, I tried applying this to 2.6.11-bk6, and it rejected:
...
patching file include/asm-i386/page.h
Hunk #2 FAILED at 28.
1 out of 2 hunks FAILED -- saving rejects to file
include/asm-i386/page.h.rej
...
There were some more rejects as well. Were there some other patches
applied first?
