b74548e76a x86: fix 2.6.27rc1 cannot boot more than 8CPUs
Jeff Chua reported that booting a !bigsmp kernel on a 16-way box
hangs silently.

this is a long-standing issue, smp start AP cpu could check the
apic id >=8 etc before trying to start it.

achieve this by moving the def_to_bigsmp check later and skip the
apicid id > 8

48d97cb65e x86: make "apic" an early_param() on 32-bit, NULL check
Cyrill Gorcunov observed:

> you turned it into early_param so now it's NULL injecting vulnerabled.
> Could you please add checking for NULL str param?

fix that.

Also, change the name of 'str' into 'arg', to make it more apparent
that this is an optional argument that can be NULL, not a string
parameter that is empty when unset.

pgd_prepopulate_pmd() when PREALLOCATED_PMDS == 0 and CONFIG_DEBUG_INFO

Adding an extra check for PREALLOCATED_PMDS == 0 [which is compiled out

eeb0d7d113 x86, debug: tone down arch/x86/kernel/mpparse.c debugging printk
commit 11a62a0560 turns some formerly
nopped debugging printks in arch/x86/kernel/mppparse.c into regular
ones. The one at the top of smp_scan_config() in particular also
prints on !CONFIG_SMP/CONFIG_X86_LOCAL_APIC kernels and UP machines
without anything resembling MP tables which makes their lowly UP
owners wonder...

Turn the former Dprintk()s into apic_printk()s instead meaning that
their printing is dependent on passing the apic=verbose (or =debug)
command line param.

On 32-bit, "apic" is a __setup() param which isn't early enough
for this code and therefore needs a followup changing it into an
early_param(). On 64-bit, it already is.

d388e5fdc4 x86: Restore proper vector locking during cpu hotplug
Having cpu_online_map change during assign_irq_vector can result
in some really nasty and weird things happening.  The one that
bit me last time was accessing non existent per cpu memory for non
existent cpus.

This locking was removed in a sloppy x86_64 and x86_32 merge patch.

Guys can we please try and avoid subtly breaking x86 when we are
merging files together?

bc033b63bb powerpc/mm: Fix attribute confusion with htab_bolt_mapping()
The function htab_bolt_mapping() is used to create permanent
mappings in the MMU hash table, for example, in order to create
the linear mapping of vmemmap.  It's also used by early boot
ioremap (before mem_init_done).

However, the way ioremap uses it is incorrect as it passes it the
protection flags in the "linux PTE" form while htab_bolt_mapping()
expects them in the hash table format.  This is made more confusing by
the fact that some of those flags are actually in the same position in
both cases.

This fixes it all by making htab_bolt_mapping() take normal linux
protection flags instead, and use a little helper to convert them to
htab flags. Callers can now use the usual PAGE_* definitions safely.

8db13a0e1e powerpc/pci: Don't keep ISA memory hole resources in the tree
When we have an ISA memory hole (ie, a PCI window that allows us to
generate PCI memory cycles at low PCI address) mixed with other
resources using a different CPU <=> PCI mapping, we must not keep
the ISA hole in the bridge resource list.

If we do, things might start trying to allocate device resources
in there and will get the PCI addresses wrong.

This fixes it by arranging to remove the ISA memory hole resource in
this case.  This fixes various cases of PCMCIA breakage on PowerBooks
using the MPC106 "grackle" bridge.

b79998fc2e powerpc: Zero fill the return values of rtas argument buffer
The kernel copy of the rtas args struct contains the return
value(s) for the specified rtas call.  These are copied back
to user space with the assumption that every value has been
set by the rtas call, which turns out to be not always true.
Thus userspace can see random values and think the call failed
when in fact it succeeded, but for some reason didn't set one
of the return values.

This fixes the problem by zeroing out the return value fields
of the rtas args struct before processing the rtas call.

31343d8a50 x86: Fix broken VMI in 2.6.27-rc..
The lowmem mapping table created by VMI need not depend on max_low_pfn
at all.  Instead we now create an extra large mapping which covers all
possible lowmem instead of the physical ram that is actually available.

This allows the vmi initialization to be done before max_low_pfn could
be computed. We also move the vmi_init code very early in the boot process
so that nobody accidentally breaks the fixmap dependancy.

b47eb4092f avr32: Clean up HMATRIX code
Introduce a few helper functions for HMATRIX configuration and clean up
the register definitions. Also add definitions for the HMATRIX master
and slave IDs on the AT32AP700x chips.

Also make the definitions in hmatrix.h available to board code by moving
it to <mach/hmatrix.h>

a8d902db22 avr32: Add MMIO address definitions for certain controllers
Hardcoded MMIO base addresses are used a few places throughout the
platform code. Move these into the chip-specific header file so that
adding support for new chips becomes a bit easier.

This file includes the appropriate chip-specific header with MMIO, IRQ
and GPIO definitions used by the platform code. It may also be used to
provide inline GPIO accessors for drivers that are willing to sacrifice
portability for faster bitbanging.

433c5f7068 sparc64: Fix end-of-stack checking in save_stack_trace().
Bug reported by Alexander Beregalov.

Before we dereference the stack frame or try to peek at the
pt_regs magic value, make sure the entire object is within
the kernel stack bounds.

4c514a5ad1 powerpc/iseries: remove the old viocons driver
This driver was declared obsolete over 2 years ago, the alternative
console driver for legacy iSeries (hvc_iseries) was made the default
over 1 year ago and this driver has been build broken for over 3
months, so remove it.

058ddee562 [ARM] Fix SMP booting with non-zero PHYS_OFFSET
The existing code tries to get the pmd for the temporary page table
by doing:

        pgd = pgd_alloc(&init_mm);
        pmd = pmd_offset(pgd, PHYS_OFFSET);

Since we have a two level page table, pmd_offset() is a no-op, so
this just has a casting effect from a pgd to a pmd - the address
argument is unused.  So this can't work.

Normally, we'd do:

	pgd = pgd_offset(&init_mm, PHYS_OFFSET);
	...
	pmd = pmd_offset(pgd, PHYS_OFFSET);

to get the pmd you want.  However, pgd_offset() takes the mm_struct,
not the (unattached) pgd we just allocated.  So, instead use:

        pgd = pgd_alloc(&init_mm);
        pmd = pmd_offset(pgd + pgd_index(PHYS_OFFSET), PHYS_OFFSET);
