Modified files:
sys/sys exec.h imgact.h
sys/i386/i386 machdep.c
sys/kern kern_exec.c imgact_elf.c
Log:
Update the ELF image activator to use some of the exec resources rather
than rolling it's own. This means that it now uses the "safe"
exec_map_first_page() to get the ld.so headers rather than risking a panic
on a page fault failure (eg: NFS server goes down).
Since all the ELF tools go to a lot of trouble to make sure everything
lives in the first page for executables, this is a win. I have not seen
any ELF executable on any system where all the headers didn't fit in the
first page with lots of room to spare.
I have been running variations of this code for some time on my pure ELF
systems.
