<pre>FreeBSD's amd64 (x86_64) kernel linker script uses MAXPAGESIZE to set the
physical and virtual addresses for the kernel.
See
<a href="https://svnweb.freebsd.org/base/head/sys/conf/ldscript.amd64?annotate=303442#l9">https://svnweb.freebsd.org/base/head/sys/conf/ldscript.amd64?annotate=303442#l9</a>
After r282560 (<a href="https://reviews.llvm.org/rL282560">https://reviews.llvm.org/rL282560</a>) lld sets MAXPAGESIZE to
0x1000 not 0x200000. The FreeBSD kernel then occupies the physical memory under
640K and the kernel panics on boot when a device that requires a low memory
allocation fails.</pre>
