scsi: libsas: direct call probe and destruct
In commit
87c8331fcf72 ("[SCSI] libsas: prevent domain rediscovery
competing with ata error handling") introduced disco mutex to prevent
rediscovery competing with ata error handling and put the whole
revalidation in the mutex. But the rphy add/remove needs to wait for the
error handling which also grabs the disco mutex. This may leads to dead
lock.So the probe and destruct event were introduce to do the rphy
add/remove asynchronously and out of the lock.
The asynchronously processed workers makes the whole discovery process
not atomic, the other events may interrupt the process. For example,
if a loss of signal event inserted before the probe event, the
sas_deform_port() is called and the port will be deleted.
And sas_port_delete() may run before the destruct event, but the
port-x:x is the top parent of end device or expander. This leads to
a kernel WARNING such as:

Make probe and destruct a direct call in the disco and revalidate function,
but put them outside the lock. The whole discovery or revalidate won't
be interrupted by other events. And the DISCE_PROBE and DISCE_DESTRUCT
event are deleted as a result of the direct call.
Introduce a new list to destruct the sas_port and put the port delete after
the destruct. This makes sure the right order of destroying the sysfs
kobject and fix the warning above.
In sas_ex_revalidate_domain() have a loop to find all broadcasted
device, and sometimes we have a chance to find the same expander twice.
Because the sas_port will be deleted at the end of the whole revalidate
process, sas_port with the same name cannot be added before this.
Otherwise the sysfs will complain of creating duplicate filename. Since
the LLDD will send broadcast for every device change, we can only
process one expander's revalidation.

debugfs: Disallow use of debugfs files when the kernel is locked down
Disallow opening of debugfs files when the kernel is locked down as various
drivers give raw access to hardware through debugfs.
Accesses to tracefs should use /sys/kernel/tracing/ rather than
/sys/kernel/debug/tracing/. Possibly a symlink should be emplaced.
Normal device interaction should be done through configfs or a miscdev, not
debugfs.
Note that this makes it unnecessary to specifically lock down show_dsts(),
show_devs() and show_call() in the asus-wmi driver.

acpi: Disable APEI error injection if the kernel is locked down
ACPI provides an error injection mechanism, EINJ, for debugging and testing
the ACPI Platform Error Interface (APEI) and other RAS features. If
supported by the firmware, ACPI specification 5.0 and later provide for a
way to specify a physical memory address to which to inject the error.
Injecting errors through EINJ can produce errors which to the platform are
indistinguishable from real hardware errors. This can have undesirable
side-effects, such as causing the platform to mark hardware as needing
replacement.
While it does not provide a method to load unauthenticated privileged code,
the effect of these errors may persist across reboots and affect trust in
the underlying hardware, so disable error injection through EINJ if
the kernel is locked down.

kbuild: Use -nostdinc in compile tests
gcc 4.8 and later include <stdc-predef.h> by default. In some
versions of eglibc that includes <bits/predefs.h>, but that may be
missing when building with a biarch compiler. Also <stdc-predef.h>
itself could be missing as we are only trying to build a kernel, not
userland.
The -nostdinc option disables this, though it isn't explicitly
documented. This option is already used when actually building
the kernel, but not by cc-option and other tests. This can result
in silently miscompiling the kernel.

x86: Make x32 syscall support conditional on a kernel parameter
Enabling x32 in the standard amd64 kernel would increase its attack
surface while provide no benefit to the vast majority of its users.
No-one seems interested in regularly checking for vulnerabilities
specific to x32 (at least no-one with a white hat).
Still, adding another flavour just to turn on x32 seems wasteful. And
the only differences on syscall entry are a few instructions that mask
out the x32 flag and compare the syscall number.
Use a static key to control whether x32 syscalls are really enabled, a
Kconfig parameter to set its default value and a kernel parameter
"syscall.x32" to change it at boot time.

mmap: Add an exception to the stack gap for Hotspot JVM compatibility
The Hotspot JVM can easily exhaust the default stack, and has a
SIGSEGV handler to cope with this by switching to a new stack segment.
However, on i386 it creates a single writable and executable page just
under the stack limit as a workaround for a bug in Exec Shield. That
together with the enlarged stack gap causes the SIGSEGV handler to be
triggered when the stack pointer is further away from the stack limit,
and it doesn't recognise this as being a stack overflow.
This specifically affects programs that use JNI. Hotspot doesn't
normally run Java code on the initial thread.
Reduce the effective stack guard gap on x86 if the previous vma is
a single page allocated as MAP_FIXED.
