Rename MDP_IRET to MDL_IRET since it is an lwp flag, not a proc one. Add an MDL_COMPAT32 flag to the lwp's md_flags, set it for 32bit lwps and use it to force 'return to user' with iret (as is done when MDL_IRET is set). Split the iret/sysret code paths much later. Remove all the replicated code for 32bit system calls - which was only needed so that iret was always used. frameasm.h for XEN contains '#define swapgs', while XEN probable never needs swapgs, this is likely to be confusing. Add a SWAPGS which is a nop on XEN and swapgs otherwise. (I've not yet checked all the swapgs in files that include frameasm.h) Simple x86 programs still work. Hijack 6.99.9 kernel bump (needed for compat32 modules)

add the guts of TLS support on amd64. based on joerg's patch, reworked by me to support 32-bit processes as well. we now keep %fs and %gs loaded with the user values while in the kernel, which means we don't need to reload them when returning to user mode.

This patch fixes the NX regression issue observed on amd64 kernels, where per-page execution right was disabled (therefore leading to the inability of the kernel to detect fraudulent use of memory mappings marked as not being executable). - replace cpu_feature and ci_feature_flags variables by cpu_feature and ci_feat_val arrays. This makes it cleaner and brings kernel code closer to the design of cpuctl(8). A warning will be raised for each CPU that does not expose the same features as the Boot Processor (BP). - the blacklist of CPU features is now a macro defined in the specialreg.h header, instead of hardcoding it inside MD initialization code; fix comments. - replace checks against CPUID_TSC with the cpu_hascounter() function. - clean up the code in init_x86_64(), as cpu_feature variables are set inside cpu_probe(). - use cpu_init_msrs() for i386. It will be eventually used later for NX feature under i386 PAE kernels. - remove code that checks for CPUID_NOX in amd64 mptramp.S, this is already performed by cpu_hatch() through cpu_init_msrs(). - remove cpu_signature and feature_flags members from struct mpbios_proc (they were never used). This patch was tested with i386 MONOLITHIC, XEN3PAE_DOM0 and XEN3_DOM0 under a native i386 host, and amd64 GENERIC, XEN3_DOM0 via QEMU virtual machines. XXX Should kernel rev be bumped? XXX A similar patch should be pulled-up for NetBSD-5, hopefully tomorrow.

Merge the ppcoea-renovation branch to HEAD. This branch was a major cleanup and rototill of many of the various OEA cpu based PPC ports that focused on sharing as much code as possible between the various ports to eliminate near-identical copies of files in every tree. Additionally there is a new PIC system that unifies the interface to interrupt code for all different OEA ppc arches. The work for this branch was done by a variety of people, too long to list here. TODO: bebox still needs work to complete the transition to -renovation. ofppc still needs a bunch of work, which I will be looking at. ev64260 still needs to be renovated amigappc was not attempted. NOTES: pmppc was removed as an arch, and moved to a evbppc target.

cpu_switchto: PCB_CR0(%r14) is a 32bit value, so don't use movq to retrieve it. Using movq would copy pcb_flags along as well, which would cause traps because bad bits would be written into %cr0 a few instructions later. This wouldn't happen for native NetBSD processes (no pcb_flags set), but it would happen for Linux processes.

Don't save/restore %fs and %gs in trapframe. The kernel won't touch them. Instead, save/restore them on context switch. For 32bit processes, save/restore the selector values only, for 64bit processes, save/restore the appropriate MSRs. Iff the defaults have been changed.

Change the process/lwp flags seen by userland via sysctl back to the P_*/L_* naming convention, and rename the in-kernel flags to avoid conflict. (P_ -> PK_, L_ -> LW_ ). Add back the (now unused) LSDEAD constant. Restores source compatibility with pre-newlock2 tools like ps or top. Reviewed by Andrew Doran.

Pass pointers to frames from assembly, do not use the 'frame on stack as argument passed by value' trick, as gcc 3.3.x makes (valid) assumptions about the stack that will not be true. Costs 2 instructions per trap/syscall on i386, 4 per interrupt for MP. One instruction per trap/syscall on amd64, 2 per interrupt for MP. I expect gcc 3.3.1 to make up for this by better optimization (it'd better..) While here, make amd64 compile again by using subr_mbr_disk.c

While the previous change actually made the code do what it intended, it was still wrong. cpu_switch() must return 1 when it switched to a different LWP, 0 if it didn't. It was doing exactly the reverse.

Rename the x86_64 port to amd64, as this is the actual name used for the processor family now. x86_64 is kept as the MACHINE_ARCH value, since it's already widely used (by e.g. the toolchain, etc), and by other operating systems.
