IA64 is also vulnerable to the huge-vma-in-executable bug in 64 bit elf
support, it just insert a vma of zero page without checking overlap, so user
can construct a elf with section begin from 0x0 to trigger this BUGON().

However, I think it's safe to check overlap before we actually insert a vma
into vma list.  And I also feel check vma overlap everywhere is unnecessary,
because invert_vm_struct will check it again, so the check is duplicated.
It's better to have invert_vm_struct return a value then let caller check if
it successes.  Here is a patch against 2.6.10.rc2-mm3 I have tested it on
i386, x86_64 and ia64 machines.

The ppc32 PowerMac cpufreq code, when using the PMU to switch the
frequency, would eventually lose interrupts.  The solution is to raise the
CPU priority at the controller level.  It's also unnecessary to call the
full PIC suspend/resume code in this case as the IO chip isn't reset,
unlike the sleep code.

Borut Lukic <borutlukic@email.si> brought to my attention that in
platform_init() on 8260 the board hook was being called too early to allow for
overrides (e.g.  different memory sizings functions or rtc, or anything else).
 This moves the call to the end of platform_init() and I suspect fixes some
unnoticed yet bugs in a number of 8260 platforms.

This changes the early CPU spinup code to be based on physical CPU ID
instead of logical.  This will make it possible to kexec off of a
different cpu than 0, for example after it's been hot-unplugged.

The booted cpu will still be mapped as logical cpu 0, since there's various
stuff in the early boot that assumes logical boot cpuid is 0.

Also, it expands the kexec boot param structure to allow the booted physical
cpuid to be passed in.  This includes bumping the version number to 2 for
backwards compat.

The ppc64 toolchains don't create dot symbols (i.e. a globally
visible ".foo" symbol for the text of function foo) any more.

This breaks the kernel compile because we refer to function text
addresses in the system call table.

Fortunately there is an option, -mcall-aixdesc, which restores the
previous behaviour, and even more fortunately, old ppc64 toolchains
understand the option as well as new ones.

Gents, what do we think of the below fix?

Thanks.

My IBM A21P laptop is getting an IRQ storm at boot.

IRQ #11 is shared between USB and e100, and USB is getting in there first.
Consequently, when e100 initialises the hardware, that interrupt line is ready
to go.  As soon as e100.c runs pci_set_master(), the interrupt hits the CPU.
But of course the e100 driver isn't ready to handle the interrupt yet, so the
system disables IRQ #11.

This only happens on warm boots (/sbin/reboot).  Things work OK from power-on.
 So I assume that the BIOS is failing to fully reset the NIC and that some
sort of interrupt is internally pending.

The patch rearranges e100_probe() so that we issue e100_hw_reset() prior to
running pci_set_master(), and fixes the problem.

Note that e100_probe() is now running e100_hw_reset() twice - I didn't remove
the later call for general paranoia reasons.

eepro100.c has the same lockup, and needs a similar fix.

Len Brown convinced me that the problem with disabling
PCI routing entries wasn't the disable as much as the
fact that ELCR needs to be updated when removing the PCI
routing. So this reverts the previous cset and updates
ELCR as suggested by Len.

Ignore offline CPUs when registering IOSAPIC interrupts.  We previously
directed interrupts even to offline CPUs, which means that if you have some
unused CPUs (e.g., you used "maxcpus="), some interrupts won't work.

This really hurts because distro installs typically use "maxcpus=1".

This fixes at least some interrupt polarity setup cases.
The ACPI guys may want to eventually do this differently, but
in the meantime this makes ACPI behaviour closer to non-ACPI
behaviour, and fixes known problems.

I'll further argue that this protects non-PCI devices that may
just share the irq routing from being screwed, but that may or
may not be an argument that everybody buys into.

This depends on the previous ptrace single-step cleanup,
and makes sure that signal handling does not lose TF events.

This allows debuggers to trace programs that set TF on their
own.

(This makes the naming of "DTRACE" purely historical, since
on x86 it now means "single step in progress").
