Unify and bump some of the NMBCLUSTERS defines. Some archs had it set to

4MB which is far too low especially when the platform is able to run MP. New limits are, amd64 = 256M; arm64, mips64, sparc64 = 64M; alpha, arm, hppa, i386, powerpc = 32M; m88k, sh = 8M Still rather conservative numbers but much better than before. At least some hangs of arm64 build boxes was caused by this. OK kettenis@, visa@

Split early startup code out of locore.S into locore0.S. Adjust link

2017-06-05T17:49:05Z

run so that this locore0.o is always at the start of the executable. But randomize the link order of all other .o files in the kernel, so that their exec/rodata/data/bss segments land all over the place. Late during kernel boot, smash the startup code with traps so that it does not point to the other randomly placed code. It has be smashed, because alpha (insecurely in my view) runs in the KSEG0 space. As a result, the internal layout of every newly build bsd kernel is different from past kernels. Internal relative offsets are not known to an outside attacker. The only known offsets are in the startup code, which is gone. Ramdisk kernels cannot be compiled like this, because they are gzip'd. When the internal pointer references change, the compression dictionary bloats and results in poorer compression.

Increase the number of mbufs on most architectures. This is based

on a guess how much memory a typical machine has. If the value is too high, users may run out of kernel memory. Then we will have to adjust this again. OK claudio@ deraadt@

PGSHIFT and PGOFSET are now contained inside the kernel namespace.

ALIGNBYTES/ALIGN/ALIGNED_POINTER can move to the MI file.

refactor sys/param.h and machine/param.h. A lot of #ifdef _KERNEL is added

2013-03-23T16:12:18Z

to keep definitions our of user space. The MD files now follow a consistant order -- all namespace intrusion is at the tail can be cleaned up independently. locore, bootblocks, and libkvm still see enough visibility to build. Checked on 90% of platforms...

Stop the song and dance where alpha param.h tries to include the world.

Link the kernel at a higher physical address, in order to accomodate SRM

with larger footprint than the usual 2MB, as encountered on some of the most recent alpha systems. Tested on many models (DEC 3000, PC164, AS500, ES40, and more)
