2013-03-12	Fix kernel profiling on MP systems by using per-CPU buffers and teach	Martin Pieuchot
	kgmon(8) to deal with them, this time without public header changes. Previously various CPUs were iterating over the same global buffer at the same time to modify it and never ended. This diff includes some ideas submited by Thor Simon to NetBSD via miod@. ok deraadt@, mikeb@, haesbaert@
2013-02-12	Back out per-CPU kernel profiling, it shouldn't modify a public header	Martin Pieuchot
	at this moment.

2013-02-02	Kernel bits for m68k/ELF, mostly from NetBSD. In addition, the `pmod' symbel	Miod Vallat
	in fpsp has to be renamed due to a clash with other parts of the kernel.
2013-01-16	replace __attribute__((unused)) with __used, which will be defined to the	David Gwynne
	right thing for whichever compiler we use. found while trying to build a profiled kernel on sparc64. solution found by guenther and refined by miod and kettenis. ok guenther@ kettenis@
2013-01-07	Move exec() libsa prototype to hp300 stand, now that it can no longer be	Miod Vallat
	found in libsa.
2013-01-05	Switch m88k ports to ELF.	Miod Vallat

2013-01-01	Remove libsa exec.c, not used by anything anymore; all boot blocks now use	Miod Vallat
	loadfile or a derivative of.
2013-01-01	Remove unused XCPPFLAGS.	Miod Vallat

2012-12-05	Remove excessive sys/cdefs.h inclusion	Theo de Raadt
	ok guenther millert kettenis
2012-10-09	Provide standalone versions of AES, AES XTS, HMAC SHA1, PBKDF2 and SHA1.	Joel Sing

2012-10-09	Provide an explicit_bzero for standalone usage.	Joel Sing

2012-07-13	bye bye SCCS	Theo de Raadt

2012-04-26	Add strnlen() to libkern.	Matthew Dempsky
	ok deraadt
2012-01-17	Remove assembly version of strlen from i386 and amd64, where it's	Mike Belopuhov
	up to 3 times slower than the C code most of the time. This was brought up by DragonflyBSD guys initially. ok deraadt, guenther. miod will not miss it.
2011-11-27	Regen.	Mark Kettenis

2011-11-27	Switch to proper PA-RISC 2.0 mnemonics. Works around a bug in the assembler	Mark Kettenis
	getting rid of the (hopefully) last bug in this code.
2011-11-27	Regen.	Mark Kettenis

2011-11-27	Fix return value of memcpy.	Mark Kettenis

2011-11-27	Oops, jsing@ changed spcopy.S without realizing that that file is generated	Mark Kettenis
	from bcopy.m4. Fix that.
2011-11-27	Regen.	Mark Kettenis

2011-11-27	Replace a few more 32-bit instructions with the proper 64-bit equivalent.	Mark Kettenis
	Also fix the return value of memcpy. With these changes, this seems to work as advertised now.
2011-09-20	Oops, forgot to remove that reference to now dead saioctl.h	Miod Vallat

2011-09-20	Remove unused libsa error code and descriptions. Anything shrinking	Miod Vallat
	boot blocks is worth having.
2011-09-20	Remove unused file before deranged boot blocks writer get ideas from it.	Miod Vallat

2011-09-19	Regen.	Mark Kettenis

2011-09-19	Avoid sign-extension when extracting the low bits of addresses when checking	Mark Kettenis
	if the addresses are 4-byte aligned. ok jsing@
2011-07-19	we need to alias __movstr* as __movmem* for gcc4	Jonathan Gray
	from NetBSD. ok miod@ drahn@
2011-07-16	Make the updated zlib compile with a debug kernel.	Joel Sing
	ok deraadt@
2011-07-07	Replace the cruddy old sys/net/zlib.[ch]. We now use the sys/lib/libz	Theo de Raadt
	code. Missing chunks of the API are imported from the libc version, with a few #ifdef's to port it into the kernel environment. The bootblocks already used the newer code, and should encounter no surprises since there are so few changes to the existing files. In the kernel, ipcomp and kernel ppp are changed to the new API. ipcomp has been tested. ok tedu the brave
2011-05-28	Do not leak memory if ufs_open() fails; reported by and ok martynas@	Miod Vallat

2011-04-14	Regen.	Joel Sing

2011-04-14	Use 64-bit operations for address manipulation.	Joel Sing

2011-04-14	Correctly load p_addr and avoid trashing the source address.	Joel Sing

2011-03-13	Change daddr_t to daddr32_t. The bootblocks on our architectures only	Theo de Raadt
	do 32-bit block spanning. If later on we get some that can/should do 64-bit, that can be done now using daddr64_t (but of course, we are taking this step to finalize the daddr_t 64-bit conversion). ok miod krw
2011-03-12	sync	Theo de Raadt

2011-03-12	In the original sparc V7 book (and in the v8 book), the divrem leaf code used	Theo de Raadt
	local registers for a few temporaries. This was changed to use two global registers. Maybe to permit use in-kernel without conflicting with the register V7 register window handlers. (Was this done by Chris Torek? Is this related to Gordon Irlam's work? Or was it in NetBSD? Hard to tell because NetBSD removed their original cvs tree.) In V8 the ABI was tightened; more global registers became offlimits in different ways. We started supporting sun4m, and did not consider this. As a result, the global registers chosen are the wrong choice. In particular, %g7 is a poor choice for upcoming TLS work. It looks like it is safer to use %g5 and %g6 since these functions are "system software". All re-entrant parts of the system save it. On sparc64 these functions are in libc per ABI requirement, but are unused. On sparc, they occur in bootblocks (no reentrancy), kernel (reentrancy saves globals; kernel is not ABI compliant), userland libc (signal handlers save globals), and ld.so (symbol binding is not re-entrant on its own). Discussed rather extensively with guenther, kettenis, miod and drahn.
2011-01-27	s/DST/DEST/ to avoid warnings when building RAMDISK kernels, which define	Miod Vallat
	TIMEZONE and DST...
2011-01-10	add a new function, explicit_bzero, to be used for erasing "secret" stuff.	Ted Unangst
	unlike normal bzero, we guarantee that the compiler will not optimize out calls to this function for otherwise dead variables. to be adjusted as needed when compilers and linkers get smarter. ok deraadt miod

	ok deraadt@
2010-12-06	- partially revert previous NENTS removal for arches which got busted.	Jasper Lievisse Adriaanse

2010-12-06	- drop NENTS(), which was yet another copy of nitems().	Jasper Lievisse Adriaanse
	no binary change ok deraadt@
2010-07-20	Add OpenSSH's timingsafe_bcmp() to libkern.	Matthew Dempsky

2010-04-01	Allow for multiple CPUs by moving to an array of cpu_info.	Joel Sing
	ok kettenis@
2009-12-12	Provide a correct version for little endian kernels... sigh	Miod Vallat

2009-11-30	Allow the bootblocks to provide an optional Elfxx_Phdr check, and abort the	Miod Vallat
	file load if necessary. Will be used very shortly.
2009-11-07	remove gcc 1 workaround we no longer care about which	Jonathan Gray
	was breaking non GNUC defining compilers. Came up during a conversation with ragge@, positive comments from several.
2009-10-28	rcsid[] and sccsid[] and copyright[] are essentially unmaintained (and	Theo de Raadt
	unmaintainable). these days, people use source. these id's do not provide any benefit, and do hurt the small install media (the 33,000 line diff is essentially mechanical) ok with the idea millert, ok dms
