[parisc-linux] binfmt_som

[Matthew Wilcox <Matthew.Wilcox@genedata.com>]

I plunged further into the binfmt_* files today and have a fair idea what needs to be done next.  One passage is slightly troubling me (page 6-126 of the
runtime arch document),

``exec_dsize
This field specifies the size in bytes of the initialised data (does
not have to be a multiple of 4k).  The actual size of the data section
in the file must be a multiple of 4k and can be padded with zeroes to
make it a multiple of 4k.''

Does this mean in the case where exec_dsize is not a multiple of 4k, it
MUST be padded with zeroes, or merely might be padded with zeroes?  If the
former, I don't need to zero them myself in the loader which would be nice.

Also, where does the bss section start?  Is it immediately after the
initialised data or at the next page boundary after it?

binfmt_som is going to be the cleanest binfmt in the kernel when I'm
finished with it :-)  [and then I'm going to clean up the others.]
