show_mem() was not correctly handling holes in the memory
map. It was treating the freed sections of the map as
though they contained valid struct page entries. This
could cause incorrect debugging output or even a kernel
panic.
This patch keeps the struct meminfo around after system
initialization so that show_mem() can use it when
scanning memory. show_mem() now walks over each bank
of each online node, rather than assuming that each node
contains a single contiguous bank.

The timer LED is unusable at HZ=large, since it's got
a hard-wired value of 100 ticks per cycle; when HZ=1024
(for example) it's essentially always-on. This patch
just makes that be HZ ticks per cycle.

e1000: Fix suspend/resume powerup and irq allocation
From: Auke Kok <auke-jan.h.kok@intel.com>
After 7.0.33/2.6.16, e1000 suspend/resume left the user with an enabled
device showing garbled statistics and undetermined irq allocation state,
where `ifconfig eth0 down` would display `trying to free already freed irq`.
Explicitly free and allocate irq as well as powerup the PHY during resume
fixes when needed.

Through some experimentation with the similarly built bcm43xx I came to
the conclusion that if the hw/firmware sets a bit in the interrupt
register, an interrupt will only be raised if that bit is included in
the interrupt mask. Hence, the interrupt mask is more like an interrupt
control mask.
This patch changes the comment to reflect that.

Now that the lockspace struct is freed when the last sysfs object is released

This adds a sync_fs superblock operation for GFS2 and removes
the journal flush from write_super in favour of sync_fs where it
ought to be. This is more or less identical to the way in which ext3

setup_lowcore() calls ctl_set_bit() which returns withs interrupts
enabled. The setup arch code is not supposed to enable interrupts that
early. Therefore use the __ctl_set_bit() variant.

Commit 7676bef9c183fd573822cac9992927ef596d584c breaks DCSS support on
s390. DCSS needs initialized struct pages to work. With the usage of
add_active_range() only the struct pages for physically present pages
are initialized.
This could be fixed if the DCSS driver would initiliaze the struct pages
itself, but this doesn't work too. This is because the mem_map array
does not include holes after the last present memory area and therefore
there is nothing that could be initialized.
To fix this and to avoid some dirty hacks revert this patch for now.
Will be added later when we move to a virtual mem_map.

Since it is becoming clear that there are just enough users of the binary
sysctl interface that completely removing the binary interface from the kernel
will not be an option for foreseeable future, we need to find a way to address
the sysctl maintenance issues.
The basic problem is that sysctl requires one central authority to allocate
sysctl numbers, or else conflicts and ABI breakage occur. The proc interface
to sysctl does not have that problem, as names are not densely allocated.
By not terminating a sysctl table until I have neither a ctl_name nor a
procname, it becomes simple to add sysctl entries that don't show up in the
binary sysctl interface. Which allows people to avoid allocating a binary
sysctl value when not needed.
I have audited the kernel code and in my reading I have not found a single
sysctl table that wasn't terminated by a completely zero filled entry. So
this change in behavior should not affect anything.
I think this mechanism eases the pain enough that combined with a little
disciple we can solve the reoccurring sysctl ABI breakage.

Cpu-hotplug locking has a minor race case caused because of setting the
variable "recursive" to NULL *after* releasing the cpu_bitmask_lock in the
function unlock_cpu_hotplug,instead of doing so before releasing the
cpu_bitmask_lock.
This was the cause of most of the recent false spurious lock_cpu_unlock
warnings.
This should fix the problem reported by Martin Lorenz reported in
http://lkml.org/lkml/2006/10/29/127.

The existing implementation of this function seems to be looking for
a one although it should be looking for a zero. This causes trouble
for the ext2 filesystem, which tends to report -ENOSPC without this

board_early_init() is left over from some early prototyping work
where we had to initialize the SDRAM controller ourselves. This
depends on the kernel being loaded into static RAM, which just
isn't possible on any commercially available products today.
In order to run without a boot loader, we need to create a zImage
stub or have the debugger initialize the SDRAM for us (for really
low-level debugging)

When I added the entries for the robust futex syscall entries, I
forgot to bump NR_SYSCALLS. The current situation is error-prone
because NR_SYSCALLS lives in entry.S where the system call limit
checks are enforced. Move the definition to asm/unistd.h in order to
make this mistake much more difficult to make.
And wire up sys_migrate_pages since the powerpc folks implemented the
compat wrapper for us.

This fixes a bug reported in:
http://bugzilla.kernel.org/show_bug.cgi?id=7438
tg3_close() turns off the PHY if WoL and ASF are both disabled. On
the next tg3_open(), some devices such as the 5752M will not be
brought up correctly without a PHY reset early in the reset sequence.
The PHY clock is needed for some internal MAC blocks to function
correctly.
This problem is fixed by always resetting the PHY early in
tg3_reset_hw() when it is called from tg3_open() or tg3_resume().
tg3_setup_phy() can then be called later in the sequence without the
reset_phy parameter set to 1, since the PHY reset is already done.
Update version to 3.68.
