d88885d092 xen/debug: Don't be so verbose with WARN on 1-1 mapping errors.
There are valid situations in which this error is not
a warning. Mainly when QEMU maps a guest memory and uses
the VM_IO flag to set the MFNs. For right now make the
WARN be WARN_ONCE. In the future we will:

 1). Remove the VM_IO code handling..
 2). .. which will also remove this debug facility.

b83c6e55ac xen: fix p2m section mismatches
Fix section mismatch warnings:
set_phys_range_identity() is called by __init xen_set_identity(),
so also mark set_phys_range_identity() as __init.
then:
__early_alloc_p2m() is called set_phys_range_identity(), so also mark
__early_alloc_p2m() as __init.

WARNING: arch/x86/built-in.o(.text+0x7856): Section mismatch in reference from the function __early_alloc_p2m() to the function .init.text:extend_brk()
The function __early_alloc_p2m() references
the function __init extend_brk().
This is often because __early_alloc_p2m lacks a __init
annotation or the annotation of extend_brk is wrong.

WARNING: arch/x86/built-in.o(.text+0x7967): Section mismatch in reference from the function set_phys_range_identity() to the function .init.text:extend_brk()
The function set_phys_range_identity() references

This is often because set_phys_range_identity lacks a __init

5ef9bdde9c FRV: Missing node arg in alloc_thread_info_node() macro
There are two alloc_thread_info_node() macros defined (one for debugging and
one for normal).  The commit that changed them most recently:

	commit b6a84016bd
	Author: Eric Dumazet <eric.dumazet@gmail.com>
	Date:   Tue Mar 22 16:30:42 2011 -0700
	Subject: mm: NUMA aware alloc_thread_info_node()

didn't add the node argument into the macro argument list for the normal macro.
This results in the following error:

kernel/fork.c:267:39: error: macro "alloc_thread_info_node" passed 2 arguments, but takes just 1
kernel/fork.c: In function 'dup_task_struct':
kernel/fork.c:267: error: 'alloc_thread_info_node' undeclared (first use in this function)

fcd8d4f498 sparc: Use the new genirq functionality
Make use of the new features in genirq:

1) Set the chip flag IRCHIP_EOI_IF_HANDLED, which ensures in the
   core code that irq_eoi() is only called when the interrupt was
   handled. That removes the extra status check in the callback.

2) Use the preflow handler, which is called from the fasteoi core code
   before the device handler. That avoids another status check and the
   open coded handler redirection.
