This patch is KASAN report adds the alloc/free stacks for page allocator
in order to help programmer to see memory corruption caused by page.
By default, KASAN doesn't record alloc/free stack for page allocator.
It is difficult to fix up page use-after-free issue.

Since the rpmsg_endpoint is created before probe is called, it's

there would be some pending work in the host_event_work workqueue while

The first generation i.MX6 processors does not send an interrupt when the
power key is pressed. It sends a power down request interrupt if the key is
released before a hard shutdown (5 second press). This should allow
software to bring down the SoC safely.

It turned out Intel Gemini Lake doesn't use the same I2C timing

I got confirmation from the Windows team that Gemini Lake systems should

If we don't care to warn about the timestamps that are clamped in
memory, maybe we could just warn when they are being written out.
Would something like this be more acceptable? I would also remove the
warning in ext4.h. I think we don't have to check if the inode is 128
bytes here (Please correct

Combine pci_dev_is_disconnected() with pci_dev_is_inaccessible() so only
one function is used to learn if we should avoid accessing a device that's
inaccessible due to surprise removal or an error condition.
The use cases for pci_dev_is_disconnected() do not need to distinguish
between a device be
The pci_device_is_present() name may encourage poor practice of calling
pci_device_is_present() and if true, assuming the device is still present
after the call. This type of practice can be racy when assuming a device
is still connected after checking.
Change pci_device_is_present() to pci_dev_is
Patch 1: Change pci_device_is_present() name to pci_dev_is_inaccessible()
to encourage only using to learn if we should not access a
device that's inaccessible. Return value will need to be reversed
to reflect the name change.
Patch 2: Relies on patch 1. Unify pci_dev_is

Add PIO mode support in receive and transmit path with RX interrupt
trigger of 16 bytes for Tegra194 and older chips.

Chips prior to Tegra186 needed delay of 3 UART clock cycles to avoid
data loss. This issue is fixed in Tegra186 and a new flag is added to
check if FIFO mode is enabled. chip data updated to check if this flag
is available for a chip. Tegra186 has new compatible to enable this
flag.
Signed-off-by:
Add new compatible string for Tegra186. It differs from earlier chips
as it has FIFO mode enable check and 8 byte DMA buffer.
Add new compatible string for Tegra194. Tegra194 has different error
tolerance levels for baud rate compared to older chips.
