[PATCH] i386: Fix broken CONFIG_COMPAT_VDSO on i386
After updating several machines to 2.6.20, I can't boot anymore the single
one of them that supports the NX bit and is configured as a 32-bit system.
My understanding is that the VDSO changes in 2.6.20-rc7 were not fully
cooked, in that with that config option enabled VDSO_SYM(x) now equals
x, meaning that an address in the fixmap area is now being passed to
apps via AT_SYSINFO. However, the page is mapped with PAGE_READONLY
rather than PAGE_READONLY_EXEC.
I'm not certain whether having app code go through the fixmap area is
intended, but in case it is here is the simple patch that makes things work
again.
