MFC r281495: Add config option PAE_TABLES for the i386 kernel. It switches pmap to use PAE format for the page tables, but does not incur other consequences of the full PAE config. In particular, vm_paddr_t and bus_addr_t are left 32bit, and max supported memory is still limited by 4GB.
The option allows to have nx permissions for memory mappings on i386 kernel, while keeping the usual i386 KBI and avoiding the kernel data sizing problems typical for the PAE config.

MFC 270850,271053,271192,271717: Save and restore FPU state across suspend and resume on i386. - Create a separate structure for per-CPU state saved across suspend and resume that is a superset of a pcb. - Store the FPU state for suspend and resume in the new structure (for amd64, this moves it out of the PCB) - On both i386 and amd64, all of the FPU suspend/resume handling is now done in C.

Add support for suspend/resume/migration operations when running as a Xen PVHVM guest.
Submitted by: Roger Pau Monné Sponsored by: Citrix Systems R&D Reviewed by: gibbs Approved by: re (blanket Xen) MFC after: 2 weeks
sys/amd64/amd64/mp_machdep.c: sys/i386/i386/mp_machdep.c: - Make sure that are no MMU related IPIs pending on migration. - Reset pending IPI_BITMAP on resume. - Init vcpu_info on resume.
sys/amd64/include/intr_machdep.h: sys/i386/include/intr_machdep.h: sys/x86/acpica/acpi_wakeup.c: sys/x86/x86/intr_machdep.c: sys/x86/isa/atpic.c: sys/x86/x86/io_apic.c: sys/x86/x86/local_apic.c: - Add a "suspend_cancelled" parameter to pic_resume(). For the Xen PIC, restoration of interrupt services differs between the aborted suspend and normal resume cases, so we must provide this information.
sys/dev/acpica/acpi_timer.c: sys/dev/xen/timer/timer.c: sys/timetc.h: - Don't swap out "suspend safe" timers across a suspend/resume cycle. This includes the Xen PV and ACPI timers.
sys/dev/xen/control/control.c: - Perform proper suspend/resume process for PVHVM: - Suspend all APs before going into suspension, this allows us to reset the vcpu_info on resume for each AP. - Reset shared info page and callback on resume.
sys/dev/xen/timer/timer.c: - Implement suspend/resume support for the PV timer. Since FreeBSD doesn't perform a per-cpu resume of the timer, we need to call smp_rendezvous in order to correctly resume the timer on each CPU.
sys/dev/xen/xenpci/xenpci.c: - Don't reset the PCI interrupt on each suspend/resume.
sys/kern/subr_smp.c: - When suspending a PVHVM domain make sure there are no MMU IPIs in-flight, or we will get a lockup on resume due to the fact that pending event channels are not carried over on migration. - Implement a generic version of restart_cpus that can be used by suspended and stopped cpus.
sys/x86/xen/hvm.c: - Implement resume support for the hypercall page and shared info. - Clear vcpu_info so it can be reset by APs when resuming from suspension.
sys/dev/xen/xenpci/xenpci.c: sys/x86/xen/hvm.c: sys/x86/xen/xen_intr.c: - Support UP kernel configurations.
sys/x86/xen/xen_intr.c: - Properly rebind per-cpus VIRQs and IPIs on resume.

Add x86/acpica/acpi_wakeup.c for amd64 and i386. Difference of suspend/resume procedures are minimized among them.
common: - Add global cpuset suspended_cpus to indicate APs are suspended/resumed. - Remove acpi_waketag and acpi_wakemap from acpivar.h (no longer used). - Add some variables in acpi_wakecode.S in order to minimize the difference among amd64 and i386. - Disable load_cr3() because now CR3 is restored in resumectx().
amd64: - Add suspend/resume related members (such as MSR) in PCB. - Modify savectx() for above new PCB members. - Merge acpi_switch.S into cpu_switch.S as resumectx().
i386: - Merge(and remove) suspendctx() into savectx() in order to match with amd64 code.
