If max_pfn is not initialized, the block layer may use wrong DMA masks.
Replace open-coded shifts by PFN_DOWN(), and drop the "0 on coldfire"
comment, as it is not even true on all Coldfires, let alone all
m68knommu platforms.

This replaces the plain loop over the sglist array with for_each_sg()
macro which consists of sg_next() function calls. Since m68k doesn't
select ARCH_HAS_SG_CHAIN, it is not necessary to use for_each_sg() in
order to loop over each sg element. But this can help find problems
with drivers that do not properly initialize their sg tables when
CONFIG_DEBUG_SG is enabled.

Pull exec domain removal from Richard Weinberger:
"This series removes execution domain support from Linux.
The idea behind exec domains was to support different ABIs. The

If an attacker can cause a controlled kernel stack overflow, overwriting
the restart block is a very juicy exploit target. This is because the
restart_block is held in the same memory allocation as the kernel stack.
Moving the restart block to struct task_struct prevents this exploit by
making the restart_block harder to locate.
Note that there are other fields in thread_info that are also easy
targets, at least on some architectures.
It's also a decent simplification, since the restart code is more or less
identical on all architectures.

Performing vma lookups without taking the mm->mmap_sem is asking for
trouble. While doing the search, the vma in question can be modified or
even removed before returning to the caller. Take the lock (shared) in
order to avoid races while iterating through the vmacache and/or rbtree.
In addition, this guarantees that the address space will remain intact
during the CPU flushing.

If the size of the first memory chunk is at least 8 or 16 MiB increase the

In a multi-platform kernel binary we only need one early console instance.
The difficulty here is that the common early console is started by
early_param(), whereas the MVME16x instance is started later by
config_mvme16x(). That means some interrupt setup must be done earlier.

Make the boot console available to more m68k platforms by leveraging
the head.S debug console.
The boot console is enabled by the "earlyprintk" command line argument
which is how most other architectures do this.
This is a change of behaviour for the Mac but does not negatively impact
the common use-case which is not debugging.
This is also a change of behaviour for other platforms because it means
the serial port stays quiet when CONFIG_EARLY_PRINTK is not enabled. This
is also an improvement for the common use-case.

Pull irq code updates from Thomas Gleixner:
"The irq department proudly presents:
- Another tree wide sweep of irq infrastructure abuse. Clear winner
of the trainwreck engineering contest was:
#include "../../../kernel/irq/settings.h"
- Tree wide update of irq_set_affinity() callbacks which miss a cpu
online check when picking a single cpu out of the affinity mask.
- Tree wide consolidation of interrupt statistics.
- Updates to the threaded interrupt infrastructure to allow explicit
wakeup of the interrupt thread and a variant of synchronize_irq()
which synchronizes only the hard interrupt handler. Both are
needed to replace the homebrewn thread handling in the mmc/sdhci
code.
- New irq chip callbacks to allow proper support for GPIO based irqs.
The GPIO based interrupts need to request/release GPIO resources
from request/free_irq.
- A few new ARM interrupt chips. No revolutionary new hardware, just
differently wreckaged variations of the scheme.
- Small improvments, cleanups and updates all over the place"
I was hoping that that trainwreck engineering contest was a April Fools'

Allow CONFIG_LOGO to enable/disable the head.S penguin logo as well as the
framebuffer console logo. This should save a few bytes. It also gets rid
of the obscure CONSOLE_PENGUIN macro.

commit: 8f945a33 (genirq: Move kstat_incr_irqs_this_cpu() to core)
unearthed the following:
arch/m68k/kernel/ints.c:34:15: error: variable 'auto_irq_chip' has initializer but incomplete type
arch/m68k/kernel/ints.c:35:2: error: unknown field 'name' specified in initializer
arch/m68k/kernel/ints.c:35:2: warning: excess elements in struct initializer [enabled by default]
The reason is that this file requires linux/irq.h and magically
pulled that in via linux/kernel_stat.h
The commit above got rid of the pointless include of linux/irq.h in
linux/kernel_stat.h and therefor broke the build.
Include linux/irq.h

For SCC initialization we cannot assume that the control register is in
the correct state to accept a register pointer. So first read from the
control register in order to "sync" up.

Add optional support to export the bootinfo used to boot the kernel in a
"bootinfo" file in procfs. This is useful with kexec.
This is based on the similar feature for ATAGS on ARM.

On m68k, get_cycles() (the default implementation for random_get_entropy())
always returns zero, providing no entropy for the random driver.
Add a hook where platforms can provide their own implementation, and wire
it up in the infrastructure provided by commit
61875f30daf60305712e25b209ef41ced2635bad ("random: allow architectures to
optionally define random_get_entropy()").

nf_init() uses virt_to_phys(), which depends on m68k_memoffset being set and
module_fixup() having been called, but this is only done in paging_init().
Hence call paging_init() before nf_init().
This went unnoticed, as virt_to_phys() is a no-op on Atari, unless you start
fiddling with the memory blocks in the bootinfo manually.

Move generic definitions used by bootstraps to uapi/asm/bootinfo.h:
- Machine types,
- CPU, FPU, and MMU types,
- struct mem_info.
Keep a copy of struct mem_info for in-kernel use, and rename it to struct
m68k_mem_info, as the exported one will be modified later.

struct mac_booter_data is no longer part of the bootinfo API, hence move it
from <asm/bootinfo.h> to <asm/macintosh.h>, dropping all unused fields in
the process.
Also remove the no longer used mac_booter_data pointer from head.S.

Since the introduction of init sections (which are located after BSS), the
bootinfo is no longer located right after the BSS, but after all kernel
sections.
