[PATCH] remove fixup_cpu_present_map()
Since the addition of boot_cpu_init(), fixup_cpu_present_map() has been a
no-op. That's because fixup_cpu_present_map() won't touch cpu_present_map if
it has any bits set, and boot_cpu_init() sets a bit.
So remove fixup_cpu_present_map().
A consequence of this (actually of the boot_cpu_init() change) is that the
architecture _must_ populate cpu_present_map itself (probably in
smp_prepare_cpus()). fixup_cpu_present_map() won't do it any more.
If the architecture doesn't do this, it'll only bring up a single CPU.
The other side effect (though less serious) is that smp_prepare_boot_cpu() no
longer needs to mark the boot cpu in the online and present maps -
boot_cpu_init() does that for everyone (to make early printks work).

Almost all users of the table addresses from the EFI system table want
physical addresses. So rather than doing the pa->va->pa conversion, just keep

on x86 but the virtual address on ia64, so dmi_scan_machine() used ioremap()
on a virtual address on ia64.
This is essentially the same as an earlier patch by Matt Tolentino:
http://marc.theaimsgroup.com/?l=linux-kernel&m=112130292316281&w=2

Pass the size, not a pointer to the size, to efi_mem_attribute_range().
This function validates memory regions for the /dev/mem read/write/mmap paths.

Enable DMI table parsing on ia64.
Andi Kleen has a patch in his x86_64 tree which enables the use of i386

drivers/char/ipmi/ipmi_si_intf.c driver for autodetecting the ports or
memory spaces where the IPMI controllers may be found.
This patch adds equivalent changes for ia64 as to what is in the x86_64
tree. In addition, I reworked the DMI detection, such that on EFI-capable
systems, it uses the efi.smbios pointer to find the table, rather than
brute-force searching from 0xF0000. On non-EFI systems, it continues the
brute-force search.
My test system, an Intel S870BN4 'Tiger4', aka Dell PowerEdge 7250, with
latest BIOS, does not list the IPMI controller in the ACPI namespace, nor
does it have an ACPI SPMI table. Also note, currently shipping Dell x8xx
EM64T servers don't have these either, so DMI is the only method for
obtaining the address of the IPMI controller.

[PATCH] i386: export: memory more than 4G through /proc/iomem
Currently /proc/iomem exports physical memory also apart from io device
memory. But on i386, it truncates any memory more than 4GB. This leads to
problems for kexec/kdump.
Kexec reads /proc/iomem to determine the system memory layout and prepares a
memory map based on that and passes it to the kernel being kexeced. Given the
fact that memory more than 4GB has been truncated, new kernel never gets to
see and use that memory.
Kdump also reads /proc/iomem to determine the physical memory layout of the
system and encodes this informaiton in ELF headers. After a crash new kernel
parses these ELF headers being used by previous kernel and vmcore is prepared
accordingly. As memory more than 4GB has been truncated, kdump never sees
that memory and never prepares ELF headers for it. Hence vmcore is truncated
and limited to 4GB even if there is more physical memory in the system.
This patch exports memory more than 4GB through /proc/iomem on i386.

[ARM] SMP: don't set cpu_*_map in smp_prepare_boot_cpu
The recent addition of boot_cpu_init() implements the initialisation
of the online, present and possible cpu maps for the boot CPU, so
there is no reason to duplicate this in the architecture
smp_prepare_boot_cpu() hook.

pfn_to_page() and others need to access both memnode_shift and the very
first bytes of memnodemap[]. If we force memnode_shift to be just before the
memnodemap array, we can reduce the memory footprint to one cache line
instead of two for most setups. This patch introduce a 'memnode' structure
where shift and map[] are carefully placed.

[PATCH] x86_64: timer interrupt lockup due to pending interrupt
o check_timer() routine fails while second kernel is booting after a crash
on an opetron box. Problem happens because timer vector (0x31) seems to be
locked.
o After a system crash, it is not safe to service interrupts any more, hence
interrupts are disabled. This leads to pending interrupts at LAPIC. LAPIC
sends these interrupts to the CPU during early boot of second kernel. Other
pending interrupts are discarded saying unexpected trap but timer interrupt
is serviced and CPU does not issue an LAPIC EOI because it think this
interrupt came from i8259 and sends ack to 8259. This leads to vector 0x31
locking as LAPIC does not clear respective ISR and keeps on waiting for
EOI.
o This patch issues extra EOI for the pending interrupts who have ISR set.
o Though today only timer seems to be the special case because in early
boot it thinks interrupts are coming from i8259 and uses
mask_and_ack_8259A() as ack handler and does not issue LAPIC EOI. But
probably doing it in generic manner for all vectors makes sense.
