CONFIG_FORTIFY_SOURCE detects various overflows at compile-time.
(6974f0c4555e ("include/linux/string.h:
add the option of fortified string.h functions)
ARCH_HAS_FORTIFY_SOURCE means that the architecture can be built and
run with CONFIG_FORTIFY_SOURCE.
Since ARM can be built and run with that flag like other architectures,
select ARCH_HAS_FORTIFY_SOURCE as default.

Reserve an F2FS feature flag and inode flag for fs-verity. This is an
in-development feature that is planned be discussed at LSF/MM 2018 [1].
It will provide file-based integrity and authenticity for read-only
files. Most code will be in a filesystem-independent module, with
smaller changes needed to individual filesystems that opt-in to
supporting the feature. An early prototype supporting F2FS is available
[2]. Reserving the F2FS on-disk bits for fs-verity will prevent users
of the prototype from conflicting with other new F2FS features.
Note that we're reserving the inode flag in f2fs_inode.i_advise, which
isn't really appropriate since it's not a hint or advice. But
->i_advise is already being used to hold the 'encrypt' flag; and F2FS's
->i_flags uses the generic FS_* values, so it seems ->i_flags can't be
used for an F2FS-specific flag without additional work to remove the
assumption that ->i_flags uses the generic flags namespace.

We can set triggers that cause a debug data collection when something
of interest happens (e.g. when too many probes are lost conscutively).
Normally, this triggers don't cause the FW to be restarted, but in
some cases that may be desired, so we recover from the problem. To
support this, add a flag that indicates that the FW should be
restarted when the trigger fires.

Currently we have a boolean variable for each cause.
This costs space, and requires to check each separately
when determining low latency.
Since we have another cause incoming, convert it to an enum.
While at it, move the retrieval of the prev value and the
assignment of the new value to be inside iwl_mvm_update_low_latency
and save the need for each caller to do it separately.

The FW does not allocate quota air time for the binding of a station
MAC before iwlmvm indicates that it is associated. Currently iwlmvm
indicates that the MAC is associated only after hearing a beacon from
the AP. In case a deauthentication frame is sent before the MAC is
associated, the frame might not be sent as the corresponding binding
is not scheduled.
To handle such cases, set IEEE80211_HW_DEAUTH_NEED_MGD_TX_PREP in the
HW flags, requesting mac80211 to call the mgd_prepare_tx() callback
before transmitting a deauthentication frame if associated but no
beacon was heard from the AP.
In addition, do not warn in iwl_mvm_mac_mgd_prepare_tx() when already
associated as now the callback can be called also when associated.

This reverts commit 4b1e84276a6172980c5bf39aa091ba13e90d6dad.
Software uses the valid bits to decide if the values can be used for
further processing or other actions. So setting the valid bits will have
software act on values that it shouldn't be acting on.
The recommendation to save all the register values does not mean that
the values are always valid.

I dug through this and I discovered that the error was caused by the
removal of struct shmid_kernel from shm.h when building on powerpc.
Except for observing the existence of "struct file *shm_file" in
struct shmid_kernel I have no clue why the structure move would cause
such a failure. I suspect shm.h always needed the forward declaration
and someting had been confusing gcc into not issuing the warning. --EWB

Some BIOSen do not handle 0-byte transfer lengths for the _LSR and _LSW

Since commit 8edc514b01e9 ("intel_th: Make SOURCE devices children of the
root device") the hub is not the parent of SOURCE devices any more, so the
new helper function should be used for that instead of always using the
parent. The intel_th_set_output() path, however, still uses the old
logic, leading to the hub driver structure being aliased with something
else, like struct pci_driver or struct acpi_driver, and an incorrect call
to an address inferred from that, potentially resulting in a crash.

ufx_realloc_framebuffer()
* Return an error code without storing it in an intermediate variable.
* Delete the label "error" and local variable "retval"
which became unnecessary with this refactoring.

Up to four checks could be repeated by the ufx_usb_probe() function
during error handling even if the relevant properties can be determined
for the involved variables before by source code analysis.
* Return directly after a call of the function "kzalloc" failed
at the beginning.
* Adjust jump targets so that extra checks can be omitted at the end.
* Delete initialisations for the variables "info" and "retval"
which became unnecessary with this refactoring.
