sched.o gets smaller and faster if we compile it with -fomit-frame-pointers,
so make this a config option. The cost is the loss of multi-depth wchan
lookups - but SysRq-T is a sufficient replacement for them anyway, so their
utility is much lower these days.
the size difference is significant:
text data bss dec hex filename
34005 3462 24 37491 9273 sched.o.before
33470 3462 24 36956 905c sched.o.after

The 64bit SMP bootup is slightly different to the 32bit one. It enables
the boot CPU local APIC timer before all CPUs are brought up. Some AMD C1E
systems have the C1E feature flag only set in the secondary CPU. Due to
the early enable of the boot CPU local APIC timer the APIC timer is
registered as a fully functional device. When we detect the wreckage during
the bringup of the secondary CPU, we need to force the boot CPU into
broadcast mode.
Check the C1E caused APIC timer disable, when the secondary APIC timer is
initialized. If the boot CPU APIC timer was registered as a functional
clock event device, then fix this up and utilize the
CLOCK_EVT_NOTIFY_BROADCAST_FORCE mechanism to force the already
registered boot CPU APIC timer into broadcast mode.
Tested by force injecting the failure mode.

There is no good reason for board platform code to mess with the ROOT_DEV.

All the users go through virt_irq_to_bucket() and essentially
want to go from a virt_irq to an INO, but we have a way
to do that already via virt_to_real_irq_table[].dev_ino.

virt_irq_to_bucket().

We were simply concatenating the devhandle and devino and using that
as the cookie, which defeats the entire purpose of the VIRQ hypervisor
interfaces.
Now that we use physical addresses for the INO buckets, we can
allocate them dynamically for VIRQs and encode the cookies as
~__pa(bucket). This allows us to test for and decode the cookie with
a simple:
brlz $reg1, 1f
xnor $reg1, %g0, $reg2
sequence.
This works because bit 64 is never set in traditional
INO vectors, and it is also never set in a physical
address. So xnor'ing the physical address of the bucket
always gives us a negative number, and thus a unique
condition we can test cheaply.
Inspired by ideas from Greg Onufer.

Currently we chain IVEC entries using 32-bit "pointers"
because we know that the ivector_table is in the main
kernel image, thus below 4GB.
This uses proper 64-bit pointers instead.
Whilst this bloats up the kernel image size, this sets
the infrastructure necessary to significantly shrink the
kernel size by using physical addresses and dynamically
allocating the ivector table.

This also makes us use the MSI queues correctly.
Each MSI queue is serviced by a normal sun4u/sun4v INO interrupt
handler. This handler runs the MSI queue and dispatches the
virtual interrupts indicated by arriving MSIs in that MSI queue.
All of the common logic is placed in pci_msi.c, with callbacks to
handle the PCI controller specific aspects of the operations.
This common infrastructure will make it much easier to add MSG
support.

Thanks to Tom Callaway for the excellent bug report and
test case.
sys_ipc() has several problems, most to due with semaphore
call handling:
1) 'err' return should be a 'long'
2) "union semun" is passed in a register on 64-bit compared
to 32-bit which provides it on the stack and therefore
by reference
3) Second and third arguments to SEMCTL are swapped compared
to 32-bit.

Added asm-sparc/irqflags.h and moved irq related code from system.h to it.
Renamed local_irq functions to raw_local_irq in irq.c.
Modified system.h to include linux/irqflags.h which includes asm/irqflags.h.
Added TRACE_IRQFLAGS_SUPPORT to Kconfig.debug.
This is the first step in adding IRQ-flags state tracing as outlined in
Documentation/irqflags-tracing.txt. These changes should be harmless
because they just move things around and rename them.
The next step is making the lowlevel entry code modifications which
to be honest are beyond my capabilities at this point.

movnt* instructions are not strongly ordered with respect to other stores,
so if we are to assume stores are strongly ordered in the rest of the 64

Use _CRS for PCI resource allocation
This patch resolves an issue where incorrect PCI memory and i/o ranges
are being assigned to hotplugged PCI devices on some IBM systems. The
resource mis-allocation not only makes the PCI device unuseable but
often makes the entire system unuseable due to resulting machine checks.
The hotplug capable PCI slots on the affected systems are not located
under a standard P2P bridge but are instead located under PCI root
bridges or subtractive decode P2P bridges. For example, the IBM x3850
contains 2 hotplug capable PCI-X slots and 4 hotplug capable PCIe slots
with the PCI-X slots each located under a PCI root bridge and the PCIe
slots each located under a subtractive decode P2P bridge.
The current i386/x86_64 PCI resource allocation code does not use _CRS
returned resource information. No other resource information source is
available for slots that are not below a standard P2P bridge so
incorrect ranges are being allocated from e820 hole causing the bad
result.
This patch causes the kernel to use _CRS returned resource info. It is
roughly based on a change provided by Matthew Wilcox for the ia64 kernel
in 2005. Due to possible buggy BIOS factor and possible yet to be
discovered kernel issues the function is disabled by default and can be
enabled with pci=use_crs.

Skip ISA ioresource alignment on some systems
To conserve limited PCI i/o resource on some IBM multi-node systems, the
BIOS allocates (via _CRS) and expects the kernel to use addresses in
ranges currently excluded by pcibios_align_resource() [i386/pci/i386.c].
This change allows the kernel to use the currently excluded address
ranges on the IBM x3800, x3850, and x3950.
