change marks[] array to uint64_t, so the code can track full 64-bit
details from the ELF header instead of faking it.
Proposal from mlarkin, tested on most architectures already

Remove {LOAD,COUNT}_TEXTA from libsa loadfile, it only made sense for a.out
kernels and we no longer have any.

Remove a.out leftovers now that libsa loadfile() will only boot ELF binaries.

First pass at removing clauses 3 and 4 from NetBSD licenses.

Not sure what's more surprising: how long it took for NetBSD to
catch up to the rest of the BSDs (including UCB), or the amount of

code that NetBSD has claimed for itself without attributing to the
actual authors.

Forgot to commit the changes to this file with the rest of the ELF32+64
pieces. Since this is where the "boot both ELF32 and ELF64" behaviour
is turned on for i386, it is quite important.

Bump version numbers too.

Revert PAE pmap for now, until the strange bug is found. This stops
the freezes many of us are seeing (especially on amd64 machines running
OpenBSD/i386).

Much testing by nick@ (as always - thanks!

implement separate PAE pmap that allows access to 64g of physmem
if supported by the cpu(s). currently not enabled by default and
not compiled into ramdisks. this grows paddr_t to 64bit but yet
leaves bus_addr_t at 32bits. measures are taken to favour dmaable
memory allocation from below 4g line such that buffer cache is
already allocated form below, pool backend allocator prefers lower
memory and then finally bounce buffers are used as last resort.
PAE is engaged only if global variable cpu_pae is manually set
to non-zero and there is physical memory present above 4g.
simplify pcibios address math to use u_long as we always will
be in the 32bit space.
