dd90533cd6 ASoC: omap: n810: Fix enum ctl accesses in a wrong type
"Jack Function", "Speaker Function" and "Input Select" ctls in n810
driver are enum, while the current driver accesses wrongly via

(Meanwhile "Headphone Switch" and "Speaker Switch" are boolean, so

3c2002aec3 cpufreq: mediatek: allow building as a module
The MT8173 cpufreq driver can currently only be built-in, but
it has a Kconfig dependency on the thermal core. THERMAL
can be a loadable module, which in turn makes this driver
impossible to build.

It is nicer to make the cpufreq driver a module as well, so
this patch turns the option in to a 'tristate' and adapts
the dependency accordingly.

The driver has no module_exit() function, so it will continue
to not support unloading, but it can be built as a module
and loaded at runtime now.

Commit cbce790059 ("PCI: designware: Make driver arch-agnostic") changed
the host bridge sysdata pointer from the ARM pci_sys_data to the DesignWare
pcie_port structure, and changed pcie-designware.c to reflect that.  But it
did not change the corresponding code in pci-keystone-dw.c, so it caused
crashes on Keystone:

In the PCI hotplug path of the Intel IOMMU driver, replace
the usage of the BUS_NOTIFY_DEL_DEVICE notifier, which is
executed before the driver is unbound from the device, with
BUS_NOTIFY_REMOVED_DEVICE, which runs after that.

This fixes a kernel BUG being triggered in the VT-d code
when the device driver tries to unmap DMA buffers and the
VT-d driver already destroyed all mappings.

dc8b4afc4a ata: ahci: don't mark HotPlugCapable Ports as external/removable
The HPCP bit is set by bioses for on-board sata ports either because
they think sata is hotplug capable in general or to allow Windows
to display a "device eject" icon on ports which are routed to an
external connector bracket.

However in Redhat Bugzilla #1310682, users report that with kernel 4.4,
where this bit test first appeared, a lot of partitions on sata drives
are now mounted automatically.

This patch should fix redhat and a lot of other distros which
unconditionally automount all devices which have the "removable"
bit set.

'function' refers to STT_FUNC from the ELF standard.

Although GAS accepts it, '.type symbol@function' is an undocumented form of
this directive. The documentation specifies a comma between the symbol and
'@function'.

1ee9f4bd1a Fix cifs_uniqueid_to_ino_t() function for s390x
This issue is caused by commit 02323db17e ("cifs: fix
cifs_uniqueid_to_ino_t not to ever return 0"), when BITS_PER_LONG
is 64 on s390x, the corresponding cifs_uniqueid_to_ino_t()
function will cast 64-bit fileid to 32-bit by using (ino_t)fileid,
because ino_t (typdefed __kernel_ino_t) is int type.

It's defined in arch/s390/include/uapi/asm/posix_types.h

    #ifndef __s390x__

    typedef unsigned long   __kernel_ino_t;
    ...
    #else /* __s390x__ */

    typedef unsigned int    __kernel_ino_t;

So the #ifdef condition is wrong for s390x, we can just still use
one cifs_uniqueid_to_ino_t() function with comparing sizeof(ino_t)
and sizeof(u64) to choose the correct execution accordingly.

b24e7ad1fd ALSA: timer: Fix ioctls for X32 ABI
X32 ABI takes the 64bit timespec, thus the timer user status ioctl becomes
incompatible with IA32.  This results in NOTTY error when the ioctl is
issued.

Meanwhile, this struct in X32 is essentially identical with the one in
X86-64, so we can just bypassing to the existing code for this
specific compat ioctl.

2251fbbc15 ALSA: rawmidi: Fix ioctls X32 ABI
Like the previous fixes for ctl and PCM, we need a fix for
incompatible X32 ABI regarding the rawmidi: namely, struct
snd_rawmidi_status has the timespec, and the size and the alignment on
X32 differ from IA32.

This patch fixes the incompatible ioctl for X32.

513ace79b6 ALSA: pcm: Fix ioctls for X32 ABI
X32 ABI uses the 64bit timespec in addition to 64bit alignment of
64bit values.  This leads to incompatibilities in some PCM ioctls
involved with snd_pcm_channel_info, snd_pcm_status and
snd_pcm_sync_ptr structs.  Fix the PCM compat ABI for these ioctls
like the previous commit for ctl API.

6236d8bb2a ALSA: ctl: Fix ioctls for X32 ABI
The X32 ABI takes the same alignment like x86-64, and this may result
in the incompatible struct size from ia32.  Unfortunately, we hit this
in some control ABI: struct snd_ctl_elem_value differs between them
due to the position of 64bit variable array.  This ends up with the
unknown ioctl (ENOTTY) error.

The fix is to add the compat entries for the new aligned struct.
