all: make copyright headers consistent with one space after period This is a subset of https://golang.org/cl/20022 with only the copyright header lines, so the next CL will be smaller and more reviewable. Go policy has been single space after periods in comments for some time. The copyright header template at: https://golang.org/doc/contribute.html#copyright also uses a single space. Make them all consistent.

cmd/internal/obj/mips, runtime: change REGTMP to R23 Leave R28 to SB register, which will be introduced in CL 19802. Change-Id: I1cf7a789695c5de664267ec8086bfb0b043ebc14 Reviewed-on: https://go-review.googlesource.com/19863 Reviewed-by: Minux Ma <minux@golang.org>

runtime: use NOFRAME on mips and mips64 This replaces frame size -4/-8 with the NOFRAME flag in mips and mips64 assembly. This was automated with: sed -i -e 's/\(^TEXT.*[A-Z]\),\( *\)\$-[84]/\1|NOFRAME,\2$0/' $(find -name '*_mips*.s') Plus a manual fix to mkduff.go. The go binary is identical on both architectures before and after this change.
