Split 4.x and 5.x signal handling so that we can keep 4.x signal handling clean and functional as 5.x evolves. This allows some of the nasty bandaids in the 5.x codepaths to be unwound. Encapsulate 4.x signal handling under COMPAT_FREEBSD4 (there is an anti-foot-shooting measure in place, 5.x folks need this for a while) and finish encapsulating the older stuff under COMPAT_43. Since the ancient stuff is required on alpha (longjmp(3) passes a 'struct osigcontext *' to the current sigreturn(2), instead of the 'ucontext_t *' that sigreturn is supposed to take), add a compile time check to prevent foot shooting there too. Add uniform COMPAT_43 stubs for ia64/sparc64/powerpc. Tested on: i386, alpha, ia64. Compiled on sparc64 (a few days ago). Approved by: re

Merge minidumps from amd64 where they were originally developed. Major differences: * since there is no direct map region, there is no custom uma memory allocator to modify to include its pages in the dumps. * Various data entries are reduced from 64 bit to 32 bit to match the native size. dump_add_page() and dump_drop_page() are still present in case one wants to arrange for arbitary pages to be dumped. This is of marginal use though because libkvm+kgdb cannot address physical memory that isn't mapped into kvm.

- Add ss2_pagezero() for zeroing pages using the movnti instruction. This instruction is enabled with SSE2 but does not use SSE registers. It is a "non-temporal" move which bypasses the cache and does not dirty lines.

void init_AMD_Elan_sc520(void);
- Add vm_paddr_t, a physical address type. This is required for systems where physical addresses larger than virtual addresses, such as i386s with PAE. - Use this to represent physical addresses in the MI vm system and in the i386 pmap code. This also changes the paddr parameter to d_mmap_t. - Fix printf formats to handle physical addresses >4G in the i386 memory detection code, and due to kvtop returning vm_paddr_t instead of u_long. Note that this is a name change only; vm_paddr_t is still the same as vm_offset_t on all currently supported platforms.

vm_paddr_t kvtop(void *addr);
To workaround an errata on certain Pentium Pro CPUs, i386 disables the local APIC in initializecpu() and re-enables it if the APIC code decides to use the local APIC after all. Rework this workaround slightly so that initializecpu() won't re-disable the local APIC if it is called after the APIC code re-enables the local APIC.

Fixed some style bugs in the removal of __P(()). The main ones were not removing tabs before "__P((", and not outdenting continuation lines to preserve non-KNF lining up of code with parentheses. Switch to KNF formatting and/or rewrap the whole prototype in some cases.

void setidt(int idx, alias_for_inthand_t *func, int typ, int dpl, int selec);
MFamd64: Add support for extended FPU states on i386. This includes support for AVX on i386. - Similar to amd64, move the FPU save area out of the PCB and instead store saved FPU state in a variable-sized buffer after the PCB on the stack. - To support the variable PCB location, alter the locore code to only use the bottom-most page of proc0stack for init386(). init386() returns the correct stack pointer to locore which adjusts the stack for thread0 before calling mi_startup(). - Don't bother setting cr3 in thread0's pcb in locore before calling init386(). It wasn't used (init386() overwrote it at the end) and it doesn't work with the variable-sized FPU save area. - Remove the new-bus attachment from npx. This was only ever useful for external co-processors using IRQ13, but those have not been supported for several years. npxinit() is now called much earlier during boot (init386()) similar to amd64. - Implement PT_{GET,SET}XSTATE and I386_GET_XFPUSTATE. - npxsave() is now only called from context switch contexts so it can use XSAVEOPT.
