[User-mode-linux-devel] The -pre8 compilation problems

[Jeff D. <jd...@ka...>]

I reproduced this problem on sourceforge.  The kernel looks at its own maps 
when it starts up because it needs to fiddle the shareability of its data and 
to mark those parts of its address space off-limits for mmap.

In arch/um/kernel/tlb.c, it reads its maps into a fixed-length array, and 
panics if it find too many.  For some reason, when you compile locally, you 
get a different number of maps than when you use the precompiled binaries.

For now, apply this patch:

I'll figure out a better way of doing this later.
