This is code that probably should never have made it into the kernel in
the first place: it depends on a driver that hadn't been reviewed yet.
During the HVC_SBI_RISCV review process a better way of doing this was
suggested, but that means this code is defunct. It's compile-time
disabled in 4.15 because the driver isn't in, so I think it's safe to
just remove this for now.

I removed this last week because of an incorrect comment:
smp_mb__after_spinlock() is actually still used, and is necessary on
RISC-V. It's been resurrected, with a comment that describes what it
actually does this time. Thanks to Andrea for finding the bug!

Johannes Berg says:
====================
Three fixes:
* for certificate C file generation, don't use hexdump as it's
not always installed by default, use pure posix instead (od/sed)
* for certificate C file generation, don't write the file if
anything fails, so the build abort will not cause a bad build
upon a second attempt
* fix locking in ieee80211_sta_tear_down_BA_sessions() which had
been causing lots of locking warnings

If something calls ioremap() with an address not aligned to PAGE_SIZE, the
returned address might be not aligned as well. This led to a probe
registered on exactly the returned address, but the entire page was armed
for mmiotracing.
On calling iounmap() the address passed to unregister_kmmio_probe() was
PAGE_SIZE aligned by the caller leading to a complete freeze of the
machine.
We should always page align addresses while (un)registerung mappings,
because the mmiotracer works on top of pages, not mappings. We still keep
track of the probes based on their real addresses and lengths though,
because the mmiotrace still needs to know what are mapped memory regions.
Also move the call to mmiotrace_iounmap() prior page aligning the address,
so that all probes are unregistered properly, otherwise the kernel ends up
failing memory allocations randomly after disabling the mmiotracer.

earlyprintk=efi,keep does not work any more with a warning
in mm/early_ioremap.c: WARN_ON(system_state != SYSTEM_BOOTING):
Boot just hangs because of the earlyprintk within the earlyprintk
implementation code itself.
This is caused by a new introduced middle state in:
69a78ff226fe ("init: Introduce SYSTEM_SCHEDULING state")
early_ioremap() is fine in both SYSTEM_BOOTING and SYSTEM_SCHEDULING
states, original condition should be updated accordingly.

Middle-layer code doing suspend-time optimizations for devices with
the DPM_FLAG_SMART_SUSPEND flag set (currently, the PCI bus type and
the ACPI PM domain) needs to make the core skip ->thaw_early and
->thaw callbacks for those devices in some cases and it sets the
power.direct_complete flag for them for this purpose.
However, it turns out that setting power.direct_complete outside of
the PM core is a bad idea as it triggers an excess invocation of
pm_runtime_enable() in device_resume().
For this reason, provide a helper to clear power.is_late_suspended
and power.is_suspended to be invoked by the middle-layer code in
question instead of setting power.direct_complete and make that code
call the new helper.

In host mode reading from DPTXSIZn returning invalid value in
dwc2_check_param_tx_fifo_sizes function.
In total TxFIFO size calculations unnecessarily reducing by ep_info.
hw->total_fifo_size can be fully allocated for FIFO's.
Added num_dev_in_eps member in dwc2_hw_params structure to save number
of IN EPs.
Added g_tx_fifo_size array in dwc2_hw_params structure to store power
on reset values of DPTXSIZn registers in forced device mode.
Updated dwc2_hsotg_tx_fifo_count() function to get TxFIFO count from
num_dev_in_eps.
Updated dwc2_get_dev_hwparams() function to store DPTXFSIZn in
g_tx_fifo_size array.
dwc2_get_host/dev_hwparams() functions call moved after num_dev_in_eps
set from hwcfg4.
Modified dwc2_check_param_tx_fifo_sizes() function to check TxFIFOn
sizes based on g_tx_fifo_size array.
Removed ep_info subtraction during calculation of tx_addr_max in
dwc2_hsotg_tx_fifo_total_depth() function. Also removed

Overlayfs is following redirects even when redirects are disabled. If this
is unintentional (probably the majority of cases) then this can be a
problem. E.g. upper layer comes from untrusted USB drive, and attacker
crafts a redirect to enable read access to otherwise unreadable
directories.
If "redirect_dir=off", then turn off following as well as creation of
redirects. If "redirect_dir=follow", then turn on following, but turn off
creation of redirects (which is what "redirect_dir=off" does now).
This is a backward incompatible change, so make it dependent on a config
option.

Historically, the XFS iomap_begin function only returned mappings for
exactly the range queried, i.e. it doesn't do XFS_BMAPI_ENTIRE lookups.
The current vfs iomap consumers are only set up to deal with trimmed
mappings. xfs_xattr_iomap_begin does BMAPI_ENTIRE lookups, which is
inconsistent with the current iomap usage. Remove the flag so that both
iomap_begin functions behave the same way.
FWIW this also fixes a behavioral regression in xattr FIEMAP that was
introduced in 4.8 wherein attr fork extents are no longer trimmed like
they used to be.

If we create a new file we will need an inode, and usually some metadata
in the parent direction. Aiming for everything to go well despite the
lack of a reservation leads to dirty transactions cancelled under a heavy
create/delete load. This patch removes those nospace transactions, which
will lead to slightly earlier ENOSPC on some workloads, but instead
prevent file system shutdowns due to cancelling dirty transactions for
others.
A customer could observe assertations failures and shutdowns due to
cancelation of dirty transactions during heavy NFS workloads as shown
below:
