Instead of calling ia32_pause() conditionally on i386 or amd64

being defined, define and use a new MD macro, cpu_spinwait(). It only expands to something on i386 and amd64, so the compiled code should be identical. Name of the macro found by: jhb Reviewed by: jhb

Backed out previous commit. Blind substitution of dev_t by `struct cdev *'

2004-06-20T03:52:50Z

was just wrong here because the dev_t's are user dev_t's.

Do the dreaded s/dev_t/struct cdev */

Bump __FreeBSD_version accordingly.

Remove the advertsing clause, per the Regent's letter dated July 22, 1999.

Cleanup by moving MD prototypes to

2003-08-17T06:42:08Z

like we have on other platforms. Move savectx() to . A lot of files got these MD prototypes through the indirect inclusion of and now need to include . The number of which is unexpectedly large... osf1_misc.c especially is tricky because szsigcode is redefined in one of the osf1 header files. Reordering of the include files was needed. linprocfs.c now needs an explicit extern declaration. Tested with: LINT

Further cleanup and : move the MI

2003-08-16T16:57:57Z

prototypes of cpu_halt(), cpu_reset() and swi_vm() from md_var.h to cpu.h. This affects db_command.c and kern_shutdown.c. ia64: move all MD prototypes from cpu.h to md_var.h. This affects madt.c, interrupt.c and mp_machdep.c. Remove is_physical_memory(). It's not used (vm_machdep.c). alpha: the MD prototypes have been left in cpu.h with a comment that they should be there. Moving them is left for later. It was expected that the impact would be significant enough to be done in a seperate commit. powerpc: MD prototypes left in cpu.h. Comment added. Suggested by: bde Tested with: make universe (pc98 incomplete)

Add getcontext, setcontext, and swapcontext as system calls.

2002-11-16T06:35:53Z

Previously these were libc functions but were requested to be made into system calls for atomicity and to coalesce what might be two entrances into the kernel (signal mask setting and floating point trap) into one. A few style nits and comments from bde are also included. Tested on alpha by: gallatin

CPU_MAXID should

Remove __P(). This was tested on the GENERIC kernel.

KSE Milestone 2

2001-09-12T08:38:13Z

Note ALL MODULES MUST BE RECOMPILED make the kernel aware that there are smaller units of scheduling than the process. (but only allow one thread per process at this time). This is functionally equivalent to teh previousl -current except that there is a thread associated with each process. Sorry john! (your next MFC will be a doosie!)
