OSS drivers are left as badly unmaintained, and now we're facing a
problem to clean up the hackish set_fs() usage in their codes. Since
most of drivers have been covered by ALSA, and the others are dead old
and inactive, let's leave them RIP.
This patch is the first step: disable the build of OSS drivers.
We'll eventually drop the whole codes and clean up later.
Note that sound/oss/dmasound is still kept, since it's a completely
different implementation of OSS, and it doesn't suffer from set_fs()
hack. Moreover, the build of ALSA is disabled on M68K by some reason,
thus disabling it shall result in a regression. This one will be
disabled / removed once when we add the support in ALSA side.

Add a new Kconfig option to enable/disable the extra warnings
from the vblank evade code. For now we'll keep the warning
about an actually missed vblank always enabled as that can have
an actual user visible impact. But if we miss the deadline
othrwise there's no real need to bother the user with that.
We'll want these warnings enabled during development however
so that we can catch regressions.
Based on the reports it looks like this is still very easy
to hit on SKL, so we have more work ahead of us to optimize
the crtiical section further.

The idea here was to avoid having to "manually" program the HW if there's
a new earliest alarm. This was lazy and bad, as it leads to loads of fun
races between inter-related callers (ie. therm).
Turns out, it's not so difficult after all. Go figure ;)
Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
Cc: stable@vger.kernel.org
At least therm/fantog "attempts" to work around this issue, which could
lead to corruption of the pending alarm list.
Fix it properly by not updating the timestamp without the lock held, or
trying to add an already pending alarm to the pending alarm list....

If the time to the next alarm is short enough, we could race with HW and

When booted as pv-guest the p2m list presented by the Xen is already
mapped to virtual addresses. In dom0 case the hypervisor might make use
of 2M- or 1G-pages for this mapping. Unfortunately while being properly
aligned in virtual and machine address space, those pages might not be
aligned properly in guest physical address space.
So when trying to obtain the guest physical address of such a page
pud_pfn() and pmd_pfn() must be avoided as those will mask away guest
physical address bits not being zero in this special case.

When running as Xen pv guest X86_BUG_SYSRET_SS_ATTRS must not be set
on AMD cpus.
This bug/feature bit is kind of special as it will be used very early
when switching threads. Setting the bit and clearing it a little bit
later leaves a critical window where things can go wrong. This time
window has enlarged a little bit by using setup_clear_cpu_cap() instead
of the hypervisor's set_cpu_features callback. It seems this larger
window now makes it rather easy to hit the problem.
The proper solution is to never set the bit in case of Xen.

Date: Thu Mar 30 10:12:39 2017 -0700
target: Fix VERIFY and WRITE VERIFY command parsing
This patch broke existing behaviour for WRITE_VERIFY because
it dropped the original SCF_SCSI_DATA_CDB assignment for
bytchk = 0 so target_cmd_size_check() no longer rejected
this case, allowing an overflow case to trigger an OOPs
in iscsi-target.
Since the short term and long term fixes are still being
discussed, revert it for now since it's late in the merge
window and try again in v4.13-rc1.

The conversion of __dax_zero_page_range() to 'struct dax_operations'
caused it to frequently fail. The mistake was treating the @size
parameter as a dax mapping length rather than just a length of the
clear_pmem() operation. The dax mapping length is assumed to be hard
coded as PAGE_SIZE.
Without this fix any page unaligned zeroing request will trigger a
-EINVAL return from bdev_dax_pgoff().

If we had badblocks/poison in the metadata area of a BTT, recreating the
BTT would not clear the poison in all cases, notably the flog area. This
is because rw_bytes will only clear errors if the request being sent
down is 512B aligned and sized.
Make sure that when writing the map and info blocks, the rw_bytes being
sent are of the correct size/alignment. For the flog, instead of doing
the smaller log_entry writes only, first do a 'wipe' of the entire area
by writing zeroes in large enough chunks so that errors get cleared.

nsio_rw_bytes can clear media errors, but this cannot be done while we
are in an atomic context due to locking within ACPI. From the BTT,
->rw_bytes may be called either from atomic or process context depending
on whether the calls happen during initialization or during IO.
During init, we want to ensure error clearing happens, and the flag
marking process context allows nsio_rw_bytes to do that. When called
during IO, we're in atomic context, and error clearing can be skipped.

Improvement of headers_install by Nicolas Dichtel.
It has been long since the introduction of uapi directories,
but the de-coupling of exported headers has not been completed.
Headers listed in header-y are exported whether they exist in
uapi directories or not. His work fixes this inconsistency.
All (and only) headers under uapi directories are now exported.
The asm-generic wrappers are still exceptions, but this is a big
step forward.

to:
module_param_hw(n, t, hwtype, p)
module_param_hw_named(n, v, t, hwtype, p)
module_param_hw_array(n, t, hwtype, m, p)
where the module parameter refers to a hardware setting
hwtype specifies the type of the resource being configured. This can
be one of:
ioport Module parameter configures an I/O port
iomem Module parameter configures an I/O mem address
ioport_or_iomem Module parameter could be either (runtime set)
irq Module parameter configures an I/O port
dma Module parameter configures a DMA channel
dma_addr Module parameter configures a DMA buffer address
other Module parameter configures some other value
Note that the hwtype is compile checked, but not currently stored (the
lockdown code probably won't require it). It is, however, there for
future use.
A bonus is that the hwtype can also be used for grepping.
The intention is for the kernel to ignore or reject attempts to set
annotated module parameters if lockdown is enabled. This applies to
options passed on the boot command line, passed to insmod/modprobe or
direct twiddling in /sys/module/ parameter files.
The module initialisation then needs to handle the parameter not being
set, by (1) giving an error, (2) probing for a value or (3) using a
reasonable default.
What I can't do is just reject a module out of hand because it may
take a hardware setting in the module parameters. Some important
modules, some ipmi stuff for instance, both probe for hardware and
allow hardware to be manually specified; if the driver is aborts with
any error, you don't get any ipmi hardware.
Further, trying to do this entirely in the module initialisation code
doesn't protect against sysfs twiddling.
[!] Note that in and of itself, this series of patches should have no
effect on the the size of the kernel or code execution - that is
left to a patch in the next series to effect. It does mark
annotated kernel parameters with a KERNEL_PARAM_FL_HWPARAM flag in
an already existing field"

to me not catching up as quickly on patch review than anything else.
Overall it seems normal though, a few small changes to the core, mostly
small non-critical fixes here and there as well as driver updates for new
and existing hardware support. The biggest things are the TI clk driver
rework to lay the groundwork for clkctrl support in the next merge window
and the AmLogic audio/graphics clk support.
Core:
* clk_possible_parents debugfs file so we know which parents a clk
could possibly have
* Fix to make clk rate change notifiers stop on the first failure instead
of continuing
New Drivers:
* Mediatek MT6797 SoCs
* hi655x PMIC clks
* AmLogic Meson SoC i2s and spdif audio clks and Mali graphics clks
* Allwinner H5 SoCs and PRCM hardware
Updates:
* Nvidia Tegra T210 cleanups and non-critical fixes
* TI OMAP cleanups in preparation for clkctrl support
* Trivial fixes like kcalloc(), devm_* conversions, and seq_puts()
* ZTE zx296718 SoC VGA clks
* Rockchip clk-ids, fixups, and rename of rk1108 to rv1108
* Support for IDT VersaClock 5P49V5935
* Renesas R-Car H3 and M3-W IMR clks and ES2.0 rev of R-Car H3 support
