This commit was manufactured to restore the state of the 4.9-RELEASE image. Releases prior to 5.3-RELEASE are omitting the secure/ and crypto/ subdirs. MFC: Always enable hyperthreading to avoid lockups due to APIC interrupt 2003-10-22T19:04:09Z John Baldwin jhb@FreeBSD.org 2003-10-22T19:04:09Z urn:sha1:455b1d51aa0c69e6b56089b9bbddbf44d43f8048 routing problems. - Enable cpu_idle_hlt for the SMP case by default since that significantly helps HTT performance. - Provide a facility for disabling individual CPUs by refusing to schedule processes on them. - Use the above to provide a sysctl for disabling or enabling all logical CPUs. The default is to disable all logical CPUs. - Remove the 'HTT' kernel option now that it is obsolete.

If you have 4G or more memory, most likely you will still have problem with dumping since PCI device windows are not currently excluded.

Interrupt time async completion callbacks for pageout operations triggered this conflict. Approved by: re (murray) MFC: PAE support, based on Jake Burkholder's work in current.

Major changes include: - introduction of vm_paddr_t to represent physical address - support for page directory pointer table - removal of (recursive) alternative address space Reviewed by: jake This commit was manufactured by cvs2svn to create branch 'RELENG_4'. 2003-06-11T00:57:00Z cvs2svn cvs2svn@FreeBSD.org 2003-06-11T00:57:00Z urn:sha1:4bfb8f80fbbeeda60747f3448f3caec8d850d791 MFC: rev 1.20: expand the APIC_ID_MASK to cover all 8 upper bits.
