e9bf14eceb libsec: avoid temp variables in chacha/salsa ENCRYPT() macro
given that we only pass uchar* with constant offsets
to the s and d arguments of ENCRYPT(), we do not need
the temporary variables sp/dp and the compiler is
smart enougth to combine the const offset with the ones
from GET4() and PUT4() and emit single load and store
instructions for the byte accesses.

47f07b2669 kernel: make the mntcache robust against fileserver like fossil that do not change the qid.vers on wstat
introducing new ctrunc() function that invalidates any caches
for the passed in chan, invoked when handling wstat with a
specified file length or on file creation/truncation.

test program to reproduce the problem:

#include <u.h>
#include <libc.h>
#include <libsec.h>

void
main(int argc, char *argv[])
{
	int fd;
	Dir *d, nd;

	fd = create("xxx", ORDWR, 0666);
	write(fd, "1234", 4);
	d = dirstat("xxx");
	assert(d->length == 4);
	nulldir(&nd);
	nd.length = 0;
	dirwstat("xxx", &nd);
	d = dirstat("xxx");
	assert(d->length == 0);
	fd = open("xxx", OREAD);
	assert(read(fd, (void*)&d, 4) == 0);
}

c67d0c699f 6c: reverse register allocation order to avoid having to spill AX,DX and CX
allocating AX,CX,DX last improves 64-bit multiplication-add
chains like a*b + c*d as the multiplication does not need to save
and restore AX and DX registers in most cases. reserving CX for
shifts also helps.

df6c190831 cfs: fix cfsctl interaction with mount cache (mount -C flag)
the root fileserver is mounted with the mount cache enabled
causing the contents of the cfsctl file to be cached as well
leading to wrong results. so after we generated the new stat
buffer, we increment the qid.vers so the cache starts out
clean.

cd15849bf2 rcpu: avoid filedescriptor conflict with <{} (thanks mycroftiv)
the rcpu client dup's fd 0,1,2 to fd 10,11,12 which
can accidentally override the pipe file descriptor
allocated by the <{} operator. to avoid this problem,
we generate the remote script as an /env file in a
separate step now.

4f72cda4ac awk: improve random number generation
don't use rand() and scale it to 0..1, instead call
native frand() which produces uniform random number.

instead of seeding the rng with time(0), use truerand().

2830cd7eb6 pc: modify cpu0 page tables in patwc() instead of current cpu ones
on 386 kernel, each processor has its own pdb where the primary
pdb for kernel mappings is on cpu0 and other cpu's lazily pull
pdb entries from cpu0 when they fault in vmapsync().

so we have to edit the table tables in the pdb of cpu0 and not
the current processor.

d48a089486 pc64: implement simple write combining for framebuffers with the PAT
on some modern machines like the x250, the bios arranges the mtrr's
and the framebuffer membar in a way that doesnt allow us to mark
the framebuffer pages as write combining, leading to slow graphics.

since the pentium III, the processor interprets the page table bit
combinations of the WT, CD and bit7 bits as an index into the
page attribute table (PAT).

to not change the semantics of the WT and CD bits, we preserve
the bit patterns 0-3 and use the last entry 7 for write combining.
(done in mmuinit() for each core).

the new patwc() function takes virtual address range and changes
the page table marking the range as write combining. no attempt
is made on invalidating tlb's. doesnt matter in our case as the
following mtrr() call in screen.c does it for us.
