A custom allocator without __GFP_COMP that copies to userspace has been
found in vmw_execbuf_process[1], so this disables the page-span checker
by placing it behind a CONFIG for future work where such things can be
tracked down later.

Merge tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dledford/rdma
Pull rdma fixes from Doug Ledford:
"This is the second pull request for the rdma subsystem. Most of the
patches are small and obvious. I took two patches in that are larger
than I wanted this late in the cycle.
The first is the hfi1 patch that implements a work queue to test the
QSFP read state. I originally rejected the first patch for this
(which would have place up to 20 seconds worth of udelays in their
probe routine). They then rewrote it the way I wanted (use delayed
work tasks to wait asynchronously up to 20 seconds for the QSFP to
come alive), so I can't really complain about the size of getting what
I asked for :-/.
The second is large because it switches the rcu locking in the debugfs
code. Since a locking change like this is done all at once, the size
it what it is. It resolves a litany of debug messages from the
kernel, so I pulled it in for -rc.
The rest are all typical -rc worthy patches I think.
There will still be a third -rc pull request from the rdma subsystem
this release. I hope to have that one ready to go by the end of this
week or early next.

The hardened usercopy is now consistently avoiding checks against const
sizes, since we really only want to perform runtime bounds checking
on lengths that weren't known at build time. To test the hardened usercopy
code, we must force the length arguments to be seen as non-const.
Signed-off-by: Kees Cook <keescook@chromium.org>
Instead of having each caller of check_object_size() need to remember to
check for a const size parameter, move the check into check_object_size()
itself. This actually matches the original implementation in PaX, though
this commit cleans up the now-redundant builtin_const() calls in the
various architectures.
Signed-off-by: Kees Cook <keescook@chromium.org>
As already done with __copy_*_user(), mark copy_*_user() as __always_inline.
Without this, the checks for things like __builtin_const_p() won't work
consistently in either hardened usercopy nor the recent adjustments for
detecting usercopy overflows at compile time.
The change in kernel text size is detectable, but very small:

Several fixes here, the main one being the change from Lars-Peter which
I'd been letting soak in -next since the merge window in case it
uncovered further issues as it's a minimal fix rather than a change
addressing the root cause of the problems (which would've been too
invasive for -rc):
- The biggest change is a fix from Lars-Peter to ensure that we don't
create overlapping rbtree nodes which in turn avoids returning
corrupt cache values to users, fixing some issues that were exposed
by some recent optimisations with certain access patterns but had
been present for a long time.
- A fix from Elaine Zhang to stop us updating the cache if we get an
I/O error when writing to the hardware.
- A fix fromm Maarten ter Huurne to avoid uninitialized defaults in
cases where we have non-readable registers but are initializing the
cache by reading from the device.

In case thermal_zone_xxx_register() returns an error, priv->zone
isn't NULL any more, but contains the error code.
This is passed to thermal_zone_device_unregister(), then. This checks
for priv->zone being NULL, but the error code is != NULL. So it works
with the error code as a pointer. Crashing immediately.
To fix this, reset priv->zone to NULL before entering
rcar_gen3_thermal_remove().

In commit 8ead9dd547 ("devpts: more pty driver interface cleanups") I
made devpts_get_priv() just return the dentry->fs_data directly. And
because I thought it wouldn't happen, I added a warning if you ever saw
a pts node that wasn't on devpts.
And no, that warning never triggered under any actual real use, but you
can trigger it by creating nonsensical pts nodes by hand.
So just revert the warning, and make devpts_get_priv() return NULL for
that case like it used to.

When reading SPI flash as MTD device, the transfer length is
directly passed to the spi driver. If the requested data size
exceeds 512KB, it will cause the time out calculation to
overflow since transfer length is 32-bit unsigned integer.
This issue is resolved by using 64-bit unsigned integer
to perform the arithmetic.

introduced code that allows inserting driver specific
struct acpi_probe_entry probe entries into ACPI linker sections
(one per-subsystem, eg irqchip, clocksource) that are then walked
to retrieve the data and function hooks required to probe the
respective kernel components.
Probing for all entries in a section is triggered through
the __acpi_probe_device_table() function, that in turn, according
to the table ID a given probe entry reports parses the table
with the function retrieved from the respective section structures
(ie struct acpi_probe_entry). Owing to the current ACPI table
parsing implementation, the __acpi_probe_device_table() function
has to share global variables with the acpi_match_madt() function, so
in order to guarantee mutual exclusion locking is required
between the two functions.
Current kernel code implements the locking through the acpi_probe_lock
spinlock; this has the side effect of requiring all code called
within the lock (ie struct acpi_probe_entry.probe_{table/subtbl} hooks)
not to sleep.
However, kernel subsystems that make use of the early probing
infrastructure are relying on kernel APIs that may sleep (eg
irq_domain_alloc_fwnode(), among others) in the function calls
pointed at by struct acpi_probe_entry.{probe_table/subtbl} entries
(eg gic_v2_acpi_init()), which is a bug.
Since __acpi_probe_device_table() is called from context
that is allowed to sleep the acpi_probe_lock spinlock can be replaced
with a mutex; this fixes the issue whilst still guaranteeing
mutual exclusion.

When the ACPI_DECLARE_PROBE_ENTRY macro was added in
commit e647b53227 ("ACPI: Add early device probing infrastructure"),
a stub macro adding an unused entry was added for the !CONFIG_ACPI
Kconfig option case to make sure kernel code making use of the
macro did not require to be guarded within CONFIG_ACPI in order to
be compiled.
The stub macro was never used since all kernel code that defines
ACPI_DECLARE_PROBE_ENTRY entries is currently guarded within
CONFIG_ACPI; it contains a typo that should be nonetheless fixed.
Fix the typo in the stub (ie !CONFIG_ACPI) ACPI_DECLARE_PROBE_ENTRY()
macro so that it can actually be used if needed.

AMD F12h machines have an erratum which can cause DIV/IDIV to behave
unpredictably. The workaround is to set MSRC001_1029[31] but sometimes
there is no BIOS update containing that workaround so let's do it
ourselves unconditionally. It is simple enough.

The debugfs RCU trips many debug kernel warnings because of potential
sleeps with an RCU read lock held. This includes both user copy calls
and slab allocations throughout the file.
This patch switches the RCU to use SRCU for file remove/access
race protection.
In one case, the SRCU is implicit in the use of the raw debugfs file
object and just works.
In the seq_file case, a wrapper around seq_read() and seq_lseek() is
used to enforce the SRCU using the debugfs supplied functions
debugfs_use_file_start() and debugfs_use_file_stop().
The sychronize_rcu() is deleted since the SRCU prevents the remove
access race.
The RCU locking is kept for qp_stats since the QP hash list is
protected using the non-sleepable RCU.

The global variable n_krcvqs stores the sum of the number of kernel
receive queues of VLs 0-7 which the user can pass to the driver through
the module parameter array krcvqs which is of type unsigned integer. If
the user passes large value(s) into krcvqs parameter array, it can cause
an arithmetic overflow while calculating n_krcvqs which is also of type
unsigned int. The overflow results in an incorrect value of n_krcvqs
which can lead to kernel crash while loading the driver.
Fix by changing the data type of n_krcvqs to unsigned long. This patch
also changes the data type of other variables that get their values from
n_krcvqs.
