commit a30dc6cf0dc51419021550152e435736aaef8799 upstream.
I got a NULL pointer dereference report when doing fuzz test:

When a queue pair is created by the following call, it will not
register the user memory if the page_store is NULL, and the
entry->state will be set to VMCIQPB_CREATED_NO_MEM.
vmci_host_unlocked_ioctl
vmci_host_do_alloc_queuepair
vmci_qp_broker_alloc
qp_broker_alloc
qp_broker_create // set entry->state = VMCIQPB_CREATED_NO_MEM;
When unmapping this queue pair, qp_host_unregister_user_memory() will
be called to unregister the non-existent user memory, which will
result in a null pointer reference. It will also change
VMCIQPB_CREATED_NO_MEM to VMCIQPB_CREATED_MEM, which should not be
present in this operation.
Only when the qp broker has mem, it can unregister the user
memory when unmapping the qp broker.
Only when the qp broker has no mem, it can register the user
memory when mapping the qp broker.

[ Upstream commit d1f278da6b11585f05b2755adfc8851cbf14a1ec ]
When scsi_dispatch_cmd was moved to scsi_lib.c and made static, some
compilers (i.e., at least gcc 8.4.0) decided to compile this
inline. This is a problem for lkdtm.ko, which inserted a kprobe
on this function for the SCSI_DISPATCH_CMD crashpoint.
Move this crashpoint one function up the call chain to
scsi_queue_rq. Though this is also a static function, it should never be
inlined because it is assigned as a structure entry. Therefore,
kprobe_register should always be able to find it.

This driver adds sysfs files that allow the BMC userspace to configure
how UARTs and physical serial I/O ports are routed.
Tested: Checked correct behavior (both read & write) on TYAN S7106
board by manually changing routing settings and confirming that bits
flow as expected. Tested for UART1 and UART3 as this board doesn't have
the other UARTs wired up in a testable way.

When PCH works under eSPI mode, the PMC (Power Management Controller) in
PCH is waiting for SUS_ACK from BMC after it alerts SUS_WARN. It is in
dead loop if no SUS_ACK assert. This is the basic requirement for the BMC
works as eSPI slave.
Also for the host power on / off actions, from BMC side, the following VW
(Virtual Wire) messages are done in firmware:
1. SLAVE_BOOT_LOAD_DONE / SLAVE_BOOT_LOAD_STATUS
2. SUS_ACK
3. OOB_RESET_ACK
4. HOST_RESET_ACK
Also, it provides monitoring interface of PLTRST_N signal through

[ Upstream commit 3ce3e45cc333da707d4d6eb433574b990bcc26f5 ]
There is an issue with the ASPM(optional) capability checking function.
A device might be attached to root complex directly, in this case,
bus->self(bridge) will be NULL, thus priv->parent_pdev is NULL.
Since alcor_pci_init_check_aspm(priv->parent_pdev) checks the PCI link's
ASPM capability and populate parent_cap_off, which will be used later by
alcor_pci_aspm_ctrl() to dynamically turn on/off device, what we can do
here is to avoid checking the capability if we are on the root complex.
This will make pdev_cap_off 0 and alcor_pci_aspm_ctrl() will simply
return when bring called, effectively disable ASPM for the device.

[ Upstream commit 7272b591c4cb9327c43443f67b8fbae7657dd9ae ]
In ibmasm_init_one, it calls ibmasm_init_remote_input_dev().
Inside ibmasm_init_remote_input_dev, mouse_dev and keybd_dev are
allocated by input_allocate_device(), and assigned to
sp->remote.mouse_dev and sp->remote.keybd_dev respectively.
In the err_free_devices error branch of ibmasm_init_one,
mouse_dev and keybd_dev are freed by input_free_device(), and return
error. Then the execution runs into error_send_message error branch
of ibmasm_init_one, where ibmasm_free_remote_input_dev(sp) is called
to unregister the freed sp->remote.mouse_dev and sp->remote.keybd_dev.
My patch add a "error_init_remote" label to handle the error of
ibmasm_init_remote_input_dev(), to avoid the uaf bugs.

commit 3641762c1c9c7cfd84a7061a0a73054f09b412e3 upstream.
Before this commit lis3lv02d_get_pwron_wait() had a WARN_ONCE() to catch
a potential divide by 0. WARN macros should only be used to catch internal
kernel bugs and that is not the case here. We have been receiving a lot of
bug reports about kernel backtraces caused by this WARN.
The div value being checked comes from the lis3->odrs[] array. Which
is sized to be a power-of-2 matching the number of bits in lis3->odr_mask.
The only lis3 model where this array is not entirely filled with non zero
values. IOW the only model where we can hit the div == 0 check is the
3dc ("8 bits 3DC sensor") model:
int lis3_3dc_rates[16] = {0, 1, 10, 25, 50, 100, 200, 400, 1600, 5000};
Note the 0 value at index 0, according to the datasheet an odr index of 0
means "Power-down mode". HP typically uses a lis3 accelerometer for HDD
fall protection. What I believe is happening here is that on newer
HP devices, which only contain a SDD, the BIOS is leaving the lis3 device
powered-down since it is not used for HDD fall protection.
Note that the lis3_3dc_rates array initializer only specifies 10 values,
which matches the datasheet. So it also contains 6 zero values at the end.
Replace the WARN with a normal check, which treats an odr index of 0
as power-down and uses a normal dev_err() to report the error in case
odr index point past the initialized part of the array.

[ Upstream commit 27ac5aada024e0821c86540ad18f37edadd77d5e ]
The refcount of the "hl_fpriv" structure is not used for the control
device, and thus hl_hpriv_put() is not called when releasing this
device.
This results with no call to put_pid(), so add it explicitly in
hl_device_release_ctrl().

[ Upstream commit f6f1f8e6e3eea25f539105d48166e91f0ab46dd1 ]
A dummy zero bit is sent preceding the data during a read transfer by the
Microchip 93LC46B eeprom (section 2.7 of[1]). This results in right shift
of data during a read. In order to ignore this bit a quirk can be added to
send an extra zero bit after the read address.
Add a quirk to ignore the zero bit sent before data by adding a zero bit
after the read address.
