This patchset addreses two problems with early loading on AMD.
First, feedback from Yinghai that find_ucode_in_initrd() should be

Change find_ucode_in_initrd() to __init and only let BSP call it
during cold boot. This is the right thing to do because only BSP will
see initrd loaded by the boot loader. APs will offset into

Because MT_DEVICE is not executable in armv7, we change
the internal SRAM memory type to MT_MEMORY_NONCACHED.
As it seems that caching this internal SRAM memory is not necessary,
we chose the this memory type.

This patch adds support for the interrupt controllers found in some
TI-Nspire models.
FIQ support was taken out to simplify the driver
code and may be added in later. Since Linux on this platform doesn't
really use FIQs, this wasn't really that important in the first
place.

Calling dev_set_name with a single paramter causes it to be handled as

The proper MIPS name for this register is EPC, so use that.
Change the asm-offsets name to KVM_VCPU_ARCH_EPC, so that the symbol
name prefix matches the structure name.

The kernel's struct pt_regs has many fields conditional on various
Kconfig variables, we cannot be exporting this garbage to user-space.
Move the kernel's definition to asm/ptrace.h, and put a uapi only
version in uapi/asm/ptrace.h gated by #ifndef __KERNEL__

Currently this is a little complex, here are the facts about how it works:

this bit is clear, we don't do anything special on an exception.

Bother. I see I was a few hours late finding this, and commit 9f29ab11ddb
is already in Linus' tree.
That's what happens when I get busy and skip a couple of days testing
linux-next :-(
So my problem comes from
iommu irq's irq_desc should be on local node ram.
Fix the return value checking problem.
create_irq() will return -1 when fail to allocate.
create_irq_nr() will return 0 when fail to allocate.
here only check !irq, so need to change it to use create_irq_nr instead.

irq_alloc_descs and irq_reserve_irqs are almost the same.
Separate code out to __irq_reserved_irqs, and other two reuse
__irq_reserve_irqs.
We will use __irq_reserve_irqs for coming ioapic hotplug support.

Hi,
Intel cpu (from IVB) include cpu, mem controller, and IIO.
When hotadd cpu physically, it will involve cpu hotplug, mem hotplug,
and pci root hotplug.
IIO includes pci host bridge, ioapic controller and iommu.
pci devices will need to use ioapic and iommu.
So to make pci root bus hotplug
We pre-reserve irq range for hot-added ioapic, and later only
some are used via realloc.
So during hot-remove, we need to clear bits in allocated_irqs
for both case.
Check if the irq_desc is there at first, and bail out early if
irq_desc is not allocated yet.
We can use irq_free_descs to clear
During ioapic hotplug, acpi_register_ioapic will be called.
Now for x86, that function is blank.
Fill that will update __mp_register_ioapic to use those ioapic.
