commit aceeafefff upstream.
Adds a driver private tee_context by moving the tee_context in struct
optee_notif to struct optee. This tee_context was previously used when
doing internal calls to secure world to deliver notification.
The new driver internal tee_context is now also when allocating driver
private shared memory. This decouples the shared memory object from its
original tee_context. This is needed when the life time of such a memory
allocation outlives the client tee_context.
This patch fixes the problem described below:
The addition of a shutdown hook by commit f25889f931 ("optee: fix tee out
of memory failure seen during kexec reboot") introduced a kernel shutdown
regression that can be triggered after running the OP-TEE xtest suites.
Once the shutdown hook is called it is not possible to communicate any more
with the supplicant process because the system is not scheduling task any
longer. Thus if the optee driver shutdown path receives a supplicant RPC
request from the OP-TEE we will deadlock the kernel's shutdown.
Fixes: f25889f931 ("optee: fix tee out of memory failure seen during kexec reboot")
Fixes: 217e0250cc ("tee: use reference counting for tee_context")

When eagerly switching PKRU in switch_fpu_finish() it checks that
current is not a kernel thread as kernel threads will never use PKRU.
It's possible that this_cpu_read_stable() on current_task
(ie. get_current()) is returning an old cached value. To resolve this
reference next_p directly rather than relying on current.
As written it's possible when switching from a kernel thread to a
userspace thread to observe a cached PF_KTHREAD flag and never restore
the PKRU. And as a result this issue only occurs when switching
from a kernel thread to a userspace thread, switching from a non kernel
thread works perfectly fine because all that is considered in that
situation are the flags from some other non kernel task and the next fpu
is passed in to switch_fpu_finish().
This behavior only exists between 5.2 and 5.13 when it was fixed by a
rewrite decoupling PKRU from xstate, in:
commit 954436989c ("x86/fpu: Remove PKRU handling from switch_fpu_finish()")
Unfortunately backporting the fix from 5.13 is probably not realistic as
it's part of a 60+ patch series which rewrites most of the PKRU handling.

commit dd2288f4a0 upstream.
Usually the kernel provides fixup routines to emulate the fldd and fstd
floating-point instructions if they load or store 8-byte from/to a not
natuarally aligned memory location.
On a 32-bit kernel I noticed that those unaligned handlers didn't worked and
instead the application got a SEGV.
While checking the code I found two problems:
First, the OPCODE_FLDD_L and OPCODE_FSTD_L cases were ifdef'ed out by the
CONFIG_PA20 option, and as such those weren't built on a pure 32-bit kernel.
This is now fixed by moving the CONFIG_PA20 #ifdef to prevent the compilation
of OPCODE_LDD_L and OPCODE_FSTD_L only, and handling the fldd and fstd
instructions.
The second problem are two bugs in the 32-bit inline assembly code, where the
wrong registers where used. The calculation of the natural alignment used %2
(vall) instead of %3 (ior), and the first word was stored back to address %1
(valh) instead of %3 (ior).

commit a58da53ffd upstream.
vhost_vsock_stop() calls vhost_dev_check_owner() to check the device
ownership. It expects current->mm to be valid.
vhost_vsock_stop() is also called by vhost_vsock_dev_release() when
the user has not done close(), so when we are in do_exit(). In this
case current->mm is invalid and we're releasing the device, so we
should clean it anyway.
Let's check the owner only when vhost_vsock_stop() is called
by an ioctl.
When invoked from release we can not fail so we don't check return
code of vhost_vsock_stop(). We need to stop vsock even if it's not
the owner.

Single page and coherent memory blocks can use different DMA masks
when the macb accesses physical memory directly. The kernel is clever
enough to allocate pages that fit into the requested address width.
When using the ARM SMMU, the DMA mask must be the same for single

tables turn into one big mess.

Fix it by checking for a "_" right after the "tp_printk" and if that

commit 7f4c5a26f7 upstream.
When connected point to point, the driver does not know the FC4's supported
by the other end. In Fabrics, it can query the nameserver. Thus the driver
must send PRLIs for the FC4s it supports and enable support based on the
acc(ept) or rej(ect) of the respective FC4 PRLI. Currently the driver
supports SCSI and NVMe PRLIs.
Unfortunately, although the behavior is per standard, many devices have
come to expect only SCSI PRLIs. In this particular example, the NVMe PRLI
is properly RJT'd but the target decided that it must LOGO after seeing the
unexpected NVMe PRLI. The LOGO causes the sequence to restart and login is
now in an infinite failure loop.
Fix the problem by having the driver, on a pt2pt link, remember NVMe PRLI
accept or reject status across logout as long as the link stays "up". When
retrying login, if the prior NVMe PRLI was rejected, it will not be sent on
the next login.

The brcmnand driver contains a bug in which if a page (example 2k byte)
is read from the parallel/ONFI NAND and within that page a subpage (512
byte) has correctable errors which is followed by a subpage with
uncorrectable errors, the page read will return the wrong status of
correctable (as opposed to the actual status of uncorrectable.)
The bug is in function brcmnand_read_by_pio where there is a check for
uncorrectable bits which will be preempted if a previous status for
correctable bits is detected.
The fix is to stop checking for bad bits only if we already have a bad
bits status.

commit 5c23b3f965 upstream.
Interacting with a NAND chip on an IPQ6018 I found that the qcomsmem NAND
partition parser was returning -EPROBE_DEFER waiting for the main smem
driver to load.
This caused the board to reset. Playing about with the probe() function
shows that the problem lies in the core clock being switched off before the
nandc_unalloc() routine has completed.
If we look at how qcom_nandc_remove() tears down allocated resources we see
the expected order is
qcom_nandc_unalloc(nandc);
clk_disable_unprepare(nandc->aon_clk);
clk_disable_unprepare(nandc->core_clk);
dma_unmap_resource(&pdev->dev, nandc->base_dma, resource_size(res),
DMA_BIDIRECTIONAL, 0);
Tweaking probe() to both bring up and tear-down in that order removes the
reset if we end up deferring elsewhere.

emulate_update_regs() should never be called with an op specifying
