The test in pdc_console_tty_close '!tty->count' was always wrong
because tty->count is decremented after tty->ops->close is called and
thus can never be zero. Hence the 'then' branch was never executed and
the timer never deleted.
This did not matter until commit 5dd5bc40f3b6 ("TTY: pdc_cons, use
tty_port"). There we needed to set TTY in tty_port to NULL, but this
never happened due to the bug above.
So change the test to really trigger at the last close by changing the
condition to 'tty->count == 1'.
Well, the driver should not touch tty->count at all. It should use
tty_port->count and count open count there itself.

It seems that there was an error with the active_low = 1 for the
LED, since it should be set to 0 (meaning that active is high,
since 0 is false, hence the confusion.
The wiki article about it confuses it, since it contradicts itself,
regarding what turns on the LED.
I have tested 3.4-rc2 on my net5501 with this patch, and it makes the LED
behave correctly, where "none" turns it off, and "default-on" turns it on,
when echoed onto the trigger "file" in /sys/class/leds.

Jana Saout confirmed that this fixes the page faults he saw.
His problem was triggered by ocfs2 and autofs symlink lookups, where the
symlink allocation was at the end of a page. But the deeper reason
seems to be the use of Xen-PV, which is what then causes him to have all
these unmapped pages, which is what then makes it a problem when the
unaligned word-at-a-time code fetches data past the end of a page.

It turns out that there are more cases than CONFIG_DEBUG_PAGEALLOC that
can have holes in the kernel address space: it seems to happen easily
with Xen, and it looks like the AMD gart64 code will also punch holes
dynamically.
Actually hitting that case is still very unlikely, so just do the
access, and take an exception and fix it up for the very unlikely case
of it being a page-crosser with no next page.
And hey, this abstraction might even help other architectures that have
other issues with unaligned word accesses than the possible missing next
page. IOW, this could do the byte order magic too.
Peter Anvin fixed a thinko in the shifting for the exception case.

Now the helper function from filter.c for negative offsets is exported,
it can be used it in the jit to handle negative offsets.
First modify the asm load helper functions to handle:
- know positive offsets
- know negative offsets
- any offset
then the compiler can be modified to explicitly use these helper
when appropriate.
This fixes the case of a negative X register and allows to lift
the restriction that bpf programs with negative offsets can't
be jited.

Recently, Ryan Wang tried to compile PPC pSeries platform without
CONFIG_EEH and eventually run into errors. Nishanth Aravamudan
helped to narrow down the root cause. Actually, the pSeries platform
depends on CONFIG_EEH heavily and that won't work properly without
EEH support.
According to Ben's suggestion, the patch make CONFIG_EEH invisible
and keep it as always selected on pSeries platform.

The switch from using irq_map to irq_alloc_desc*() for managing irq
number allocations introduced new bugs in some of the powerpc
interrupt code. Several functions rely on the value of NR_IRQS to
determine the maximum irq number that could get allocated. However,
with sparse_irq and using irq_alloc_desc*() the maximum possible irq
number is now specified with 'nr_irqs' which may be a number larger
than NR_IRQS. This has caused breakage on powermac when
CONFIG_NR_IRQS is set to 32.
This patch removes most of the direct references to NR_IRQS in the
powerpc code and replaces them with either a nr_irqs reference or by
using the common for_each_irq_desc() macro. The powerpc-specific
for_each_irq() macro is removed at the same time.
Also, the Cell axon_msi driver is refactored to remove the global
build assumption on the size of NR_IRQS and instead add a limit to the
maximum irq number when calling irq_domain_add_nomap().

The mpc8xx driver uses a reference to NR_IRQS that is buggy. It uses
NR_IRQs for the array size of the ppc_cached_irq_mask bitmap, but
NR_IRQs could be smaller than the number of hardware irqs that
ppc_cached_irq_mask tracks.
Also, while fixing that problem, it became apparent that the interrupt
controller only supports 32 interrupt numbers, but it is written as if
it supports multiple register banks which is more complicated.
This patch pulls out the buggy reference to NR_IRQs and fixes the size
of the ppc_cached_irq_mask to match the number of HW irqs. It also
drops the now-unnecessary code since ppc_cached_irq_mask is no longer
an array.
