Bruce Evans	ebedb5ad97	Cleaned up all headers that include <sys/ioctl.h> or <sys/ioccom.h>: ... - don't include <sys/ioctl.h> in any header. Include <sys/ioccom.h> instead. This was already done in 4.4Lite for the most important ioctl headers. Header spam currently increases kernel build times by 10-20%. There are more than 30000 #includes (not counting duplicates) for compiling LINT. - include <sys/types.h> if and only it is necessary to make the header almost self-sufficient (some ioctl headers still need structs from elsewhere). - uniformized idempotency ifdefs. Copied the style in the 4.4Lite ioctl headers.	1996-09-21 14:59:43 +00:00
Garrett Wollman	d69e850255	Add support for Pentium and Pentium Pro performance counters. ... (This code is as yet untested; to come after man page is written.) This also adds inlines to cpufunc.h for the RDTSC, RDMSR, WRMSR, and RDPMC instructions. The user-mode interface is via a subdevice of mem.c; there is also a kernel-size interface which might be used to aid profiling.	1996-03-26 19:57:56 +00:00
