The -ffunction-sections puts each text in .text.function_name section.
Without this patch, most functions are placed outside _text..._etext
area and it breaks show_stacktrace(), etc.

While updating the rcu code, I noticed that do_nmi() for AVR32 is odd:
There is an nmi_enter() call without an nmi_exit().
This can't be correct, it breaks rcu (at least the preempt version) and
lockdep.

On AVR32, all parameters beyond the 5th are passed on the stack. System
calls don't use the stack -- they borrow a callee-saved register
instead. This means that syscalls that take 6 parameters must be called
through a stub that pushes the last parameter on the stack.
This patch adds a stub for sync_file_range syscall on AVR32
architecture. Tested with uClibc snapshot.

Commit deac93df26b20cf8438339b5935b5f5643bc30c9 ("lib: Correct printk
%pF to work on all architectures") broke the non modular builds by
moving an essential function into modules.c. Fix this by moving it
out again and into asm/sections.h as an inline. To do this, the
definition of struct ppc64_opd_entry has been lifted out of modules.c
and put in asm/elf.h where it belongs.

One of the changes in the bootwrapper makefile introduced the dtbImage
targets for boards that need a simple zImage with a DTB embedded in
them (595be948cce574ff2d5dde5d0426a636a4363c70, "[POWERPC]
bootwrapper: Build multiple cuImages"). When this was done, it broke
booting on the Holly board as the zImage.holly wrapper did not get the
DTB embedded properly.
This changes the target for the Holly board to a dtbImage so that the
wrapper includes the vmlinux, wrapper bits, and DTB.

For Freescale 8xxx devices that use an MPIC, the interrupt numbers in
the device tree must be 16 greater than the values documented in the
reference manual. In these chips, the MPIC is wired to use the first
16 numbers for external interrupts, but the documentation numbers
internal interrupts from 0.
In the MPC8610 HPCD device tree, the interrupt properties for the DMA
channels for DMA2 were not the adjusted values. This fixes that.

Based upon a report by Meelis Roos.
Any function call can try to access the current
thread register via the _mcount hooks when the kernel
is built with -pg (via ftrace or STACK_DEBUG).
That can't be setup properly very early on during
the bootup of other cpus for sun4u and some early
sun4v systems.
So add notrace markers to these specific functions, so
that _mcount doesn't get invoked too early.

We no longer put the top-level PCI controller device into the
PCI layer device list. So pbm->pci_bus->self is always NULL.
Therefore, use direct PCI config space accesses to get at
the PCI controller's PCI_STATUS register.

PCI_DMA_BUS_IS_PHYS was defined to be zero, which meant we ignored
the DMA mask for IDE and SCSI transfers. This is wrong - we have
no DMA translation hardware. We want to obey DMA masks so that the

Such a crash is possible if the CPU in this system is a 64-bit
processor which doesn't support NX (ie, old Intel P4 -based64-bit
processors).
Certainly, if we support such processors, then we should start with
_PAGE_NX initially clear in __supported_pte_flags, and then set it once
we've established that the processor does indeed support NX. That will
prevent early_ioremap - or anything else - from trying to set it.
The simple fix is to simply call check_efer() earlier.

Change the MN10300 fault handler to make it check in_atomic() rather than
in_interrupt() as commit 6edaf68a87d17570790fd55f0c451a29ec1d6703 did for other

Author: Peter Zijlstra <a.p.zijlstra@chello.nl>
Date: Wed Dec 6 20:32:18 2006 -0800
[PATCH] mm: arch do_page_fault() vs in_atomic()
In light of the recent pagefault and filemap_copy_from_user work I've
gone through all the arch pagefault handlers to make sure the
inc_preempt_count() 'feature' works as expected.
Several sections of code (including the new filemap_copy_from_user)
rely on the fact that faults do not take locks under increased preempt
count.
