ASoC: Fixes for v4.5
This is far too big a set of fixes for this late in the release cycle
but the overwhelming bulk is essentially the same simple fix from
Takashi for a cut'n'pasted 64 bit cleanliness issue in the userspace
interface where drivers were accessing things using the wrong element in
a union which worked OK on 32 bit platforms as the correct element
happened to be aligned the same way but with 64 bit platforms ABIs are
different and the two members of the union are laid out in different
places. They aren't all tagged to stable since some of these chips have
vanishingly little chance of being used in 64 bit systems.
The other changes are:
- A fix for Qualcomm devices to work on big endian systems. The
original change is actually correct but triggered a bug in regmap
which is too invasive to fix for this cycle and can be worked around
by just letting regmap pick the default.
- A fix for the Samsung I2S driver locking which wasn't using IRQ safe
spinlocks when it needed to.
- A fix for the new Intel Sky Lake driver forgetting that C pointer
arithmetic takes the type of the pointer into consideration.
- A revert of a change to the FSL SSI driver that broke some systems.
- A fix for the cleanup path of the wm9713 driver.
- A fix for some incorrect register definitions in the ADAU17x1 driver
that caused misclocking in some configurations.
- A fix for the tracepoints for jack detection to avoid using an
internal field of the core jack structure which is no longer present
in all configurations.
- A fix for another of the new Intel drivers which tried to write to a
string literal.

The accuracy of Bzy_Mhz and Busy% depend on reading
the TSC, APERF, and MPERF close together in time.
When there is a very short measurement interval,
or a large system is profoundly idle, the changes
in APERF and MPERF may be very small.
They can be small enough that an expensive interrupt
between reading APERF and MPERF can cause the APERF/MPERF
ratio to become inaccurate, resulting in invalid
calculation and display of Bzy_MHz.
A dummy APERF read of APERF makes this problem
much more rare. Apparently this 1st systemn call
after exiting a long stretch of idle is when we
typically see expensive timer interrupts that cause
large jitter.
For the cases that dummy APERF read fails to prevent,
we compare the latency of the APERF and MPERF reads.
If they differ by more than 2x, we re-issue them.

At the same time x200 cannot be included in has_snb_msrs since

were erroneously calculated using bclk of 133MHz,

Currently we have an incorrect behaviour when multiple devices
are present under the weim node. For example:
&weim {
...
status = "okay";
sram@0,0 {
...
status = "okay";
};
mram@0,0 {
...
status = "disabled";
};
};
In this case only the 'sram' device should be probed and not 'mram'.
However what happens currently is that the status variable is ignored,
causing the 'sram' device to be disabled and 'mram' to be enabled.
Change the weim_parse_dt() function to use
for_each_available_child_of_node()so that the devices marked with
'status = disabled' are not probed.

Some machines have EFI regions in page zero (physical address
0x00000000) and historically that region has been added to the e820
map via trim_bios_range(), and ultimately mapped into the kernel page
tables. It was not mapped via efi_map_regions() as one would expect.
Alexis reports that with the new separate EFI page tables some boot
services regions, such as page zero, are not mapped. This triggers an
oops during the SetVirtualAddressMap() runtime call.
For the EFI boot services quirk on x86 we need to memblock_reserve()
boot services regions until after SetVirtualAddressMap(). Doing that
while respecting the ownership of regions that may have already been
reserved by the kernel was the motivation behind this commit:
7d68dc3f10 ("x86, efi: Do not reserve boot services regions within reserved areas")
That patch was merged at a time when the EFI runtime virtual mappings
were inserted into the kernel page tables as described above, and the
trick of setting ->numpages (and hence the region size) to zero to
track regions that should not be freed in efi_free_boot_services()
meant that we never mapped those regions in efi_map_regions(). Instead
we were relying solely on the existing kernel mappings.
Now that we have separate page tables we need to make sure the EFI
boot services regions are mapped correctly, even if someone else has
already called memblock_reserve(). Instead of stashing a tag in
->numpages, set the EFI_MEMORY_RUNTIME bit of ->attribute. Since it
generally makes no sense to mark a boot services region as required at
runtime, it's pretty much guaranteed the firmware will not have
already set this bit.
For the record, the specific circumstances under which Alexis
triggered this bug was that an EFI runtime driver on his machine was
responding to the EVT_SIGNAL_VIRTUAL_ADDRESS_CHANGE event during
SetVirtualAddressMap().
The event handler for this driver looks like this,
sub rsp,0x28
lea rdx,[rip+0x2445] # 0xaa948720
mov ecx,0x4
call func_aa9447c0 ; call to ConvertPointer(4, & 0xaa948720)
mov r11,QWORD PTR [rip+0x2434] # 0xaa948720
xor eax,eax
mov BYTE PTR [r11+0x1],0x1
add rsp,0x28
ret
Which is pretty typical code for an EVT_SIGNAL_VIRTUAL_ADDRESS_CHANGE
handler. The "mov r11, QWORD PTR [rip+0x2424]" was the faulting
instruction because ConvertPointer() was being called to convert the
address 0x0000000000000000, which when converted is left unchanged and
remains 0x0000000000000000.
The output of the oops trace gave the impression of a standard NULL
pointer dereference bug, but because we're accessing physical
addresses during ConvertPointer(), it wasn't. EFI boot services code
is stored at that address on Alexis' machine.
