This creates linux/openfw.h and includes asm/prom.h from it. We also include linux/openfw.h from asm/prom.h while we transition. Signed-off-by: Stephen Rothwell <redacted> --- include/asm-powerpc/prom.h | 39 +++------------------------- include/asm-sparc/prom.h | 48 ++++------------------------------- include/asm-sparc64/prom.h | 48 ++++------------------------------- include/linux/openfw.h | 59 ++++++++++++++++++++++++++++++++++++++++++++ 4 files changed, 76 insertions(+), 118 deletions(-) create mode 100644 include/linux/openfw.h This applies on top of all the previous patches I sent (including a merge of the sparc64 and powerpc for-2.6.22 trees). So if people can't get it to apply, at least I would like some comments on the direction. (I told Rusty about the circular inclusion below and he didn't throw up, so I figure it isn't too bad as a temporary measure.) I have built allmodconfig (modified slightly) for Powerpc, Sparc64 and Sparc. (All of which fail during the module post processing but for reasons not related to these patches as far as I can see.) -- Cheers, Stephen Rothwell sfr@canb.auug.org.au
