2013-06-17m68k kernel memcpy/memmove/bcopy implementation in libkern, remove ovbcopy, ↵Janne Johansson
fix for larger than 128k size copies. Parts from deraadt@, ok (and off-by-one fix) miod@
2013-06-15Fast memmove() implementation for PowerPC, from NetBSD via martin@; withMiod Vallat
bcopy() and memcpy() wrappers.
2013-06-15Fix evil typo causing the wrong pointer to be returned for < 32 bytesMiod Vallat
memcpy() or memmove().
2013-06-15Preserve %o5 around Lbcopy_doubles; prevents the return value from memcpy()Miod Vallat
and memmove() to be incorrect for copies of 32 bytes or more, when the source and destination addresses are nicely aligned.
2013-06-15Make bcopy() involve memmove(), not memcpy().Miod Vallat
Do not bogusly return NULL if dst == src (spotted by tedu@)
2013-06-15Correctly handle a length of zero in memcpy().Miod Vallat
Return the original destination pointer in memcpy() and memmove().
2013-06-15Don't return garbage in memcpy() but the original destination pointer.Miod Vallat
2013-06-15give bcopy() the ovbcopy() semanticsMiod Vallat

Now deficient architectures can use this if they need to. conf/files already tries to pull this in (pointed out by mlarkin)

2013-06-11Optimize memcpy(9) by always doing a forward copy; it should never be usedMark Kettenis
for overlapping copies. Attempt to be instruction cache friendly by turning things around and make memcpy(9) use the forward copy branch of memmove(9), and implement bcopy(9) by swapping its arguments and dropping into memmove(9). Same change as the one just made to for hppa.

2013-03-12Fix kernel profiling on MP systems by using per-CPU buffers and teachMartin 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@
