Fix RX sensitivity issue for SSPHY data lines for SDM660 by
writing zero value to PERIPH_SS_USB3PHY_QSERDES_RXA/B_RX_MODE_00
registers. Otherwise it could cause superspeed enumeration failure
with some Host machines.

On 32bit systems, bitmap storing the iova information is stored in per
page and each page represents the 128MB of IOVA. So, for the
alloc_iova() to return the requested range, iova size should be aligned
to 128MB.

The wcnss platform driver update the wlan calibration data
by the user space wlan daemon. The wlan user space daemon store
the updated wlan calibration data reported by wlan firmware in
user space and write it back to the wcnss platform calibration
data buffer for the calibration data download and update.
During the wlan calibration data store and retrieve operation
there are some potential race condition which leads to memory leak
and buffer overflow during the context switch.
Fix the above issue by adding protection code and avoid usage of
global pointer during the device file read and write operation.

Dump sync logs only when a fence is not signalled
for SYNC_DUMP_TIME_LIMIT or more. This is necessary
to reduce CPU hogging because of excessive sync logs
dumped due to fence timeouts which are less than
SYNC_DUMP_TIME_LIMIT and are harmless.

Set the size of bitmap area properly to ensure the proper iova address
to be returned by the bitmap_() API's through alloc_iova(). The current
implementation causes the bitmap index search out of bounds of a page
which can lead to the randomn corruption issues.

This separates the kref for ion handles into two components.
Userspace requests through the ioctl will hold at most one
reference to the internally used kref. All additional requests
will increment a separate counter, and the original reference is
only put once that counter hits 0. This protects the kernel from
a poorly behaving userspace.

Commit <be0960374> ("scsi: ufs: scale up the gear in 2 steps") introduced
a bug where we would not scale up the gear to HS-G3 if
UFS_DEVICE_QUIRK_HS_G1_TO_HS_G3_SWITCH quirk isn't enabled for UFS device.
Fix this by allowing HS-G3 scaling irrespective of quirk state.

Request for memory with GFP_NOIO so that new IO
request is not raised while reclaiming the memory when
system is having low memory. With GFP_KERNEL a deadlock
is possible with scm function requsting for memory during
PFK operation intiated by block layer through storage
driver. With low memory system will try to
reclaim some memory. If GFP_KERNEL is used this
will lead to IO operation through storage driver
which is already serving PFK encryption call hence
can not take up this IO request causing deadlock.

Add Minidump support for clients to get minimum required data
at the time of system crash. The Minidump table resides in SMEM,
BOOT(SBL) will iterate the table entries and dumps out (to USB/Flash)
the data in address location.
Any client can register to this table with static or known addresses,
as currently Minidump doesn't support dumping of dynamic data structures.
To simplify post processing, we create an ELF header, where each entry in
the minidump table is a section in elf header.
If Memory dump table enabled, Dump all data entries registered with MDT.
Enable Minidump:
echo mini > /sys/kernel/dload/dload_mode
