ELF_ROUND (round to higher alignment boundary), and use them properly.
Also, change a bit of code in elf_load_psection to use the next ELF_ROUND
macro. This fixes a bug found by Robert Baron <rvb+@cs.cmu.edu> where
elf_load_psection, if given a properly aligned address at which to load
the section, would round actually load it at the next highest alignment
boundary.
for NOEXEC and NOSUID, and make sure the interpreter file is executable.
The mount point checks are done because, even though the interpreter
is not the program being 'executed', code from the interpreter is being
executed, and so the mount point's flags should be respected.
macros to use to remove #ifdefs from the machine ID case check.
Eventually, these headers will contain other information, e.g.
machine-dependent relocation information, etc.
specific probe function did not specify it. It picks the same address
as mmap() does for a non-fixed map at address 0. See also the comment
around a similar line of code in vm/vm_mmap.c.
it's text or data; use the entry point instead (this solves some trouble
with ELF executables with strange permissions)
* Incorporate some fixes from r_friedl@informatik.uni-kl.de sent to
netbsd-bugs a while ago
