adjust patch set for 3.18: rediffs and drops

Once again try a 'real' fix for ACPI _DEP (the one currently
in upstream review). Re-diff the ath6kl SDIO ID patch. Drop
the UEFI 'big arse revert', should be merged upstream now. For
now do not apply the mic fix patch as I *think* a correct fix
has gone upstream:
http://mailman.alsa-project.org/pipermail/alsa-devel/2014-October/081780.html
Update config-x86-generic with a bunch more ASoC drivers to
disable.

Subject: [RFC, V2] ACPI: Add _DEP(Operation Region Dependencies) support to fix
battery issue on the Asus T100TA
From: "lan,Tianyu" <tianyu.lan@intel.com>

ACPI 5.0 introduces _DEP to designate device objects that OSPM should
assign a higher priority in start ordering due to future operation region
accesses.
On Asus T100TA, ACPI battery info are read from a I2C slave device via
I2C operation region. Before I2C operation region handler is installed,
battery _STA always returns 0. There is a _DEP method of designating
start order under battery device node.
This patch is to implement _DEP feature to fix battery issue on the Asus T100TA.
Introducing acpi_dep_list and adding dep_unmet count in the struct
acpi_device. During ACPI namespace scan, create struct acpi_dep_data for a
valid pair of master (device pointed to by _DEP)/slave(device with _DEP), record
master's and slave's ACPI handle in it and put it into acpi_dep_list. The dep_unmet
count will increase by one if there is a device under its _DEP. Driver's probe() should
return EPROBE_DEFER when find dep_unmet larger than 0. When I2C operation
region handler is installed, remove all struct acpi_dep_data on the acpi_dep_list
whose master is pointed to I2C host controller and decrease slave's dep_unmet.
When dep_unmet decreases to 0, all _DEP conditions are met and then do acpi_bus_attach()
for the device in order to resolve battery _STA issue on the Asus T100TA.

Change since V1:
Rework struct acpi_dep_data, record master and slave's ACPI handle.
Rename dep_present with dep_unmet and make it as a count. Increase dep_unmet
during bootup and decrease it when associated operation region is installed.

From 8054c405f0acc8ecb74b7e29675a1e6894afedb0 Mon Sep 17 00:00:00 2001

Subject: [PATCH] Revert "efi/x86: efistub: Move shared dependencies to
<asm/efi.h>"
This reverts commit f23cf8bd5c1f ("efi/x86: efistub: Move shared
dependencies to <asm/efi.h>") as well as the x86 parts of commit
f4f75ad5741f ("efi: efistub: Convert into static library").
The road leading to these two reverts is long and winding.
The above two commits were merged during the v3.17 merge window and
turned the common EFI boot stub code into a static library. This
necessitated making some symbols global in the x86 boot stub which
introduced new entries into the early boot GOT.
The problem was that we weren't fixing up the newly created GOT entries
before invoking the EFI boot stub, which sometimes resulted in hangs or
resets. This failure was reported by Maarten on his Macbook pro.
The proposed fix was commit 9cb0e394234d ("x86/efi: Fixup GOT in all
boot code paths"). However, that caused issues for Linus when booting
his Sony Vaio Pro 11. It was subsequently reverted in commit
f3670394c29f.
So that leaves us back with Maarten's Macbook pro not booting.
At this stage in the release cycle the least risky option is to revert
the x86 EFI boot stub to the pre-merge window code structure where we
explicitly #include efi-stub-helper.c instead of linking with the static
library. The arm64 code remains unaffected.
We can take another swing at the x86 parts for v3.18.
