2017-01-15	libsec: avoid temp variables in chacha/salsa ENCRYPT() macro	cinap_lenrek
	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.

2017-01-12	kernel: make the mntcache robust against fileserver like fossil that do not ↵	cinap_lenrek
	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); }

	connection without a tcp reset (used by go)

2017-01-08	6c: reverse register allocation order to avoid having to spill AX,DX and CX	cinap_lenrek
	allocating AX,CX,DX last improves 64-bit multiplication-add chains like ab + cd as the multiplication does not need to save and restore AX and DX registers in most cases. reserving CX for shifts also helps.
2017-01-07	aux/data2s: compress output	cinap_lenrek
	encode printable characters litteraly, use D() macro to reduce DATA instruction overhead. this halves the time spend assembling $CONF.root.s for the kernel build.
2017-01-06	cfs: fix cfsctl interaction with mount cache (mount -C flag)	cinap_lenrek
	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.
2017-01-02	6c, 8c: fix "DI botch" evacuating DI/SI/CX registers to ".save" variables	cinap_lenrek

2016-12-29	vgaigfx: enable softscreen by default	cinap_lenrek
	given that the igfx driver doesnt provide any acceleration functions and drawing is usually faster with double buffering as it eleminates reads over the pci bus, enable softscreen by default.

2016-12-19	rcpu: avoid filedescriptor conflict with <{} (thanks mycroftiv)	cinap_lenrek
	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.
2016-12-18	awk: improve random number generation	cinap_lenrek
	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().
2016-12-17	pc: modify cpu0 page tables in patwc() instead of current cpu ones	cinap_lenrek
	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.
2016-12-17	pat write combinding support for 386 kernel, honor cpuid bits	cinap_lenrek

2016-12-15	pc64: implement simple write combining for framebuffers with the PAT	cinap_lenrek
	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.
