Commit 06e8935feb ("optimized SDIO IRQ handling for single irq")
introduced some spurious calls to SDIO function interrupt handlers,
such as when the SDIO IRQ thread is started, or the safety check
performed upon a system resume. Let's add a flag to perform the
optimization only when a real interrupt is signaled by the host
driver and we know there is no point confirming it.

This driver is broken since 2.6.31 when the traditional i.MX1
support was removed.
In theory the i.MX1 mmc controller can be supported by the mxcmmc
driver which basically is the same hardware. However, the i.MX1
controller has severe bugs which made several workarounds necessary which
resulted in a different driver structure. At that time it seemed easier
to write a second driver to support hardware without bugs.
As noone cared for the i.MX1 driver for a long time and it does
not compile, remove it.

Commit c79396c191 ("mmc: sdhci: prevent card detection activity
for non-removable cards") disables card detection where the cards
are marked as non-removable.
This makes sense, but the implementation detail of calling
mmc_card_is_removable() causes some problems, because
mmc_card_is_removable() is overloaded with CONFIG_MMC_UNSAFE_RESUME
semantics.
In the OLPC XO case, we need CONFIG_MMC_UNSAFE_RESUME because our root
filesystem is stored on SD, but we also have external SD card slots
where we want automatic card detection.
Refine the check to only apply to hosts marked as MMC_CAP_NONREMOVABLE,
which is defined to mean that the card is *really* nonremovable. This
could be revisited in future if we find a way to improve
CONFIG_MMC_UNSAFE_RESUME semantics.

This continues the theme started with vm_brk() and vm_munmap():
vm_mmap() does the same thing as do_mmap(), but additionally does the
required VM locking.
This uninlines (and rewrites it to be clearer) do_mmap(), which sadly
duplicates it in mm/mmap.c and mm/nommu.c. But that way we don't have
to export our internal do_mmap_pgoff() function.
Some day we hopefully don't have to export do_mmap() either, if all
modular users can become the simpler vm_mmap() instead. We're actually
very close to that already, with the notable exception of the (broken)
use in i810, and a couple of stragglers in binfmt_elf.

of_have_populated_dt() is not expected to be used in drivers but
instead only in early platform init code.
Drivers on the other hand should rely on dev->of_node or of_match_device().
Besides usage of of_have_populated_dt() also throws up build error as below
which was reported by Balaji TK, when omap_hsmmc is built as a module.
ERROR: "allnodes" [drivers/mmc/host/omap_hsmmc.ko] undefined!

eMMC v4.5 discard operation is significantly different from the
existing trim operation because it is not guaranteed to work with
the new sanitize operation. Consequently mmc_can_trim() is
separated from mmc_can_discard().
Also the new discard operation does not result in the sectors being
set to all-zeros, so discard_zeroes_data must not be set.
In addition, the new discard has the same timeout as trim, but from
v4.5 trim is defined to use the hc timeout. The timeout calculation
is adjusted accordingly.

It breaks reboot on at least one Thinkpad T43, as reported by Jörg Otte:
"On reboot it shuts down as normal.
The last lines displayed are:
>Unmounting temporary filesystems.. [OK]
>Deactivating swap... [OK]
>Unmounting local filesystems... [OK]
>Will now restart
> Restarting system
Then I hear it accessing the cd-drive, but then it's being stuck."
Jörg bisected the regression to this commit.
That commit fixes another machine (see
https://bugzilla.kernel.org/show_bug.cgi?id=11533
for details) that has a BIOS bug and doesn't support ACPI reset.
However, at least one of those other reporters no longer even has the
machine in question, and had a different workaround to begin with.
Besides, it clearly was a buggy BIOS. Let's not break the correct case
to fix that case.

Commit 24aa07882b ("memblock, x86: Replace memblock_x86_reserve/
free_range() with generic ones") replaced x86 specific memblock
operations with the generic ones; unfortunately, it lost zero length
operation handling in the process making the kernel panic if somebody
tries to reserve zero length area.
There isn't much to be gained by being cranky to zero length operations
and panicking is almost the worst response. Drop the BUG_ON() in
memblock_reserve() and update memblock_add_region/isolate_range() so
that all zero length operations are handled as noops.

Fixes for a few regressions of HD-audio, originated partly from 3.4
and partly 3.3.
The fixes for ThinkPad docking-station are for 3.3 kernels, thus they
are based on 3.3 then merged back to 3.4, so that they can be merged
to stable tree cleanly. The non-trivial merge conflicts are because
of this action.
In addition, a copule of trivial fixes for documentation and a long-
statnding issue in the listing of built-in sound driver at boot time.

This reverts commit b960d6c43a.
If we have another thread (very likely) touched the list, we
end up hitting a problem "that the next element is wrong because
we should be able to cope with that. The problem is that the
next->next pointer would be set LIST_POISON1. " (Stefano's
comment on the patch).
Reverting for now.

Rather than loading firmware specific for the xtal frequency, just use
the standard firmware and set the xtal frequency after firmware upload.
The modified firmware will never be released, so we're better off
merging this now rather than waiting for v3.5.
