2008-04-17x86: fix VisualWS and Voyager kexec build failuresRandy Dunlap
without this patch: VOYAGER: kernel/built-in.o: In function `crash_kexec': (.text+0x28588): undefined reference to `machine_crash_shutdown' VISWS: kernel/built-in.o: In function `crash_kexec': /next-20080401/kernel/kexec.c:1074: undefined reference to `machine_crash_shutdown' make[1]: *** [.tmp_vmlinux1] Error 1 because arch/x86/kernel/reboot.c isn't built since CONFIG_X86_BIOS_REBOOT=n, so machine_crash_shutdown() isn't available. This patch does seem a small bit odd since the KEXEC help text says that kexec is independent of the system firmware.

2008-04-17x86: MPSC should use P6 NOPsHugh Dickins
I've now noticed that the machine I call MPENTIUM4 for 32-bit kernels is called MPSC for 64-bit kernels, and in that case it still doesn't get the P6 NOPs it ought to. hpa explains that MK8 should still be excluded, so it's just a matter of including MPSC along with MPENTIUM4.

We should call for kfree if only we really need it. Though it's safe to call kfree with NULL pointer passed in this code we've already tested the pointer and can eliminate the call Signed-off-by: Cyrill Gorcunov <gorcunov@gmail.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>

2008-04-17x86: support for new UV apicJack Steiner
UV supports really big systems. So big, in fact, that the APICID register does not contain enough bits to contain an APICID that is unique across all cpus. The UV BIOS supports 3 APICID modes: - legacy mode. This mode uses the old APIC mode where APICID is in bits [31:24] of the APICID register. - x2apic mode. This mode is whitebox-compatible. APICIDs are unique across all cpus. Standard x2apic APIC operations (Intel-defined) can be used for IPIs. The node identifier fits within the Intel-defined portion of the APICID register. - x2apic-uv mode. In this mode, the APICIDs on each node have unique IDs, but IDs on different node are not unique. For example, if each mode has 32 cpus, the APICIDs on each node might be 0 - 31. Every node has the same set of IDs. The UV hub is used to route IPIs/interrupts to the correct node. Traditional APIC operations WILL NOT WORK. In x2apic-uv mode, the ACPI tables all contain a full unique ID (note: exact bit layout still changing but the following is close): nnnnnnnnnnlc0cch n = unique node number l = socket number on board c = core h = hyperthread Only the "lc0cch" bits are written to the APICID register. The remaining bits are supplied by having the get_apic_id() function "OR" the extra bits into the value read from the APICID register. (Hmmm.. why not keep the ENTIRE APICID register in per-cpu data....) The x2apic-uv mode is recognized by the MADT table containing: oem_id = "SGI" oem_table_id = "UV-X" Signed-off-by: Jack Steiner <steiner@sgi.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>

2008-04-17x86: parsing for ACPI "SAPIC" tableJack Steiner
Add kernel support for new ACPI "sapic" tables that contain 16-bit APICIDs. This patch simply adds parsing of an optional SAPIC table if present. Otherwise, the traditional local APIC table is used. Note: the SAPIC table is not a new ACPI table - it exists on other architectures but is not currently recognized by x86_64.

2008-04-17x86: increase size of APICIDJack Steiner
Increase the number of bits in an apicid from 8 to 32. By default, MP_processor_info() gets the APICID from the mpc_config_processor structure. However, this structure limits the size of APICID to 8 bits. This patch allows the caller of MP_processor_info() to optionally pass a larger APICID that will be used instead of the one in the mpc_config_processor struct.

2008-04-17x86: add functions to determine if platform is a UV platformJack Steiner
Add functions that can be used to determine if an x86_64 system is a SGI "UV" system. UV systems come in 3 types and are identified by the OEM ID in the MADT. Signed-off-by: Jack Steiner <steiner@sgi.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2008-04-17x86: change GET_APIC_ID() from an inline function to an out-of-line functionJack Steiner

2008-04-17x86: cleanup - rename VM_MASK to X86_VM_MASKgorcunov@gmail.com
This patch renames VM_MASK to X86_VM_MASK (which in turn defined as alias to X86_EFLAGS_VM) to better distinguish from virtual memory flags. We can't just use X86_EFLAGS_VM instead because it is also used for conditional compilation Signed-off-by: Cyrill Gorcunov <gorcunov@gmail.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
