If the order of UART nodes is changed in the device tree, then tty dev
devices are attached to different serial ports causing the console to
be directed to a different physical serial port. The "serial" aliases
in the device tree should prevent this.
This patch ensures that the UART driver creates tty devices that
honour these aliases if a device tree is present.

This structure might have made sense many years ago, but at this
point it is only used in one specific driver, and referenced in
stale comments elsewhere. Rather than change the sunsu.c driver,
simply move the struct to be within the exclusive domain of that
driver, so it won't get inadvertently picked up and used by other
serial drivers going forward. The comments referencing the now
driver specific struct are updated accordingly.
Note that 8250.c has a struct that is similar in usage, with the
name serial8250_config; but is 100% independent and untouched here.

The addition of 8250-like entities continues to grow, while this
driver has a snapshot of a select few common 8250 UARTs. So it
has no need to grow with the new additions, since it calls out
its own (largely historic) static list which does not grow.

The struct serial_uart_config is hardly used at all, and the
use case like this one are somewhat needless. Remove the
trivial usage so that we can remove serial_uart_config.
Since the type field isn't really used at all, we also delete
the initialization and references of it here as well.

Remove the clock configuration from imx_setup_ufcr(). This
isn't needed here and will cause garbage output if done.
To be be sure that we only touch the bits we want (TXTL and RXTL)
we have to mask out all other bits of the UFCR register. Add
one non-existing bit macro for this, too (bit 6, DCEDTE on i.MX6).

The console feature's write routing is unsafe on SMP with
the startup/shutdown call.
There could be several consumers of the console
* the kernel printk
* the init process using /dev/kmsg to call printk to show log
* shell, which open /dev/console and write with sys_write()
The shell goes into the normal uart open/write routing,
but the other two go into the console operations.
The open routing calls imx serial startup, which will write USR1/2
register without any lock and critical with imx_console_write call.
Add a spin_lock for startup/shutdown/console_write routing.
This patch is a port from Freescale's Android kernel.

For non PCI-based stacks, this function call
usb_disable_xhci_ports(to_pci_dev(hcd->self.controller));
made from xhci_shutdown is not applicable.
Ideally, we wouldn't have any PCI-specific code on
a generic driver such as the xHCI stack, but it looks
like we should just stub usb_disable_xhci_ports() out
for non-PCI devices.

This patch is intended to work around a known issue on the
SN65LVPE502CP USB3.0 re-driver that can delay the negotiation
between a device and the host past the usual handshake timeout.
If that happens on the first insertion, the host controller
port will enter in Compliance Mode and NO port status event will
be generated (as per xHCI Spec) making impossible to detect this
event by software. The port will remain in compliance mode until
a warm reset is applied to it.
As a result of this, the port will seem "dead" to the user and no
device connections or disconnections will be detected.
For solving this, the patch creates a timer which polls every 2
seconds the link state of each host controller's port (this
by reading the PORTSC register) and recovers the port by issuing a
Warm reset every time Compliance mode is detected.
If a xHC USB3.0 port has previously entered to U0, the compliance
mode issue will NOT occur only until system resumes from
sleep/hibernate, therefore, the compliance mode timer is stopped
when all xHC USB 3.0 ports have entered U0. The timer is initialized
again after each system resume.
Since the issue is being caused by a piece of hardware, the timer
will be enabled ONLY on those systems that have the SN65LVPE502CP
installed (this patch uses DMI strings for detecting those systems)
therefore making this patch to act as a quirk (XHCI_COMP_MODE_QUIRK
has been added to the xhci stack).
This patch applies for these systems:
Vendor: Hewlett-Packard. System Models: Z420, Z620 and Z820.
This patch should be backported to kernels as old as 3.2, as that was
the first kernel to support warm reset. The kernels will need to
contain both commit 10d674a82e553cb8a1f41027bb3c3e309b3f6804 "USB: When
hot reset for USB3 fails, try warm reset" and commit
8bea2bd37df08aaa599aa361a9f8b836ba98e554 "usb: Add support for root hub
port status CAS". The first patch add warm reset support, and the
second patch modifies the USB core to issue a warm reset when the port
is in compliance mode.

My test platform (Intel DX79SI) boots reliably under BIOS, but frequently
crashes when booting via UEFI. I finally tracked this down to the xhci
handoff code. It seems that reads from the device occasionally just return
0xff, resulting in xhci_find_next_cap_offset generating a value that's
larger than the resource region. We then oops when attempting to read the
value. Sanity checking that value lets us avoid the crash.
I've no idea what's causing the underlying problem, and xhci still doesn't
actually *work* even with this, but the machine at least boots which will
probably make further debugging easier.
This should be backported to kernels as old as 2.6.31, that contain the
commit 66d4eadd8d067269ea8fead1a50fe87c2979a80d "USB: xhci: BIOS handoff

This patch fixes a race condition that results in memory
corruption when using cleancache.
The race exists between the zcache shrinker handler,
shrink_zcache_memory() and cleancache_get_page().
In most cases, the shrinker will both evict a zbpg
from its buddy list and flush it from tmem before a
cleancache_get_page() occurs on that page. A subsequent
cleancache_get_page() will fail in the tmem layer.
In the rare case that two occur together and the
cleancache_get_page() path gets through the tmem
layer before the shrinker path can flush tmem,
zbud_decompress() does a check to see if the zbpg is a
"zombie", i.e. not on a buddy list, which means the shrinker
is in the process of reclaiming it. If the zbpg is a zombie,
zbud_decompress() returns -EINVAL.
However, this return code is being ignored by the caller,
zcache_pampd_get_data_and_free(), which results in the
caller of cleancache_get_page() thinking that the page has
been properly retrieved when it has not.
This patch modifies zcache_pampd_get_data_and_free() to
convey the failure up the stack so that the caller of
cleancache_get_page() knows the page retrieval failed.
This needs to be applied to stable trees as well.
zcache-main.c was named zcache.c before v3.1, so
I'm not sure how you want to handle trees earlier
than that.

When the interface is down, the hardware is powered off.
However, the suspend handler currently tries to send host sleep commands
(when wakeup params are set) in this configuration, causing a system hang
when going into suspend (the commands will never complete).
Avoid this by detecting this situation and simply returning from
the suspend handler without doing anything special.

This feature had been disabled in ath9k because the code to support
it was incomplete, but now the code is in sync with the internal QCA
codebase, so it's time to enable it.
On many newer devices, the calibration is assumed to be done with PA
linearization enabled.
Tests with a particular AR933x device showed that the signal emitted
at full power was highly distorted and unreliable with PA linearization
disabled. With this patch, the signal becomes clear and stability
is improved.

Before PAPRD training can run, the card needs to have sent a packet for
thermal calibration. Sending a dummy packet with the PAPRD training flag
set causes a crash under some circumstance.
Fix the code by replacing the dummy tx with a delay that waits for a
real packet tx to have occurred.

The interrupt is no longer handling it. While it shouldn't fire (wraparound
is highly unlikely), the consequences would be fatal (interrupt storm).
Disable the interrupt to prevent that from happening.

According to the vendor driver v2.6.0.1, during the rf register init the SRAM
voltage should be increased to 1.35V and after 1ms decreased back to 1.2V. This
patch adds the field setting of LDO_CFG0_LDO_CORE_VLEVEL accordingly.

When we send a command to firmware, we assumed that cmd_size
will be always less than or equal to the structure size of
host_cmd_ds_command. However, this is no longer true after
we added AP support. There are some AP commands that Custom
IE TLVs are included in command buffer, hence the cmd_size
gets enlarged by the TLV data. We need to increase the skb
length for the extra data.

When running 32-bit pvops-dom0 and a driver tries to allocate a coherent
DMA-memory the xen swiotlb-implementation returned memory beyond 4GB.
The underlaying reason is that if the supplied driver passes in a
DMA_BIT_MASK(64) ( hwdev->coherent_dma_mask is set to 0xffffffffffffffff)
our dma_mask will be u64 set to 0xffffffffffffffff even if we set it to
DMA_BIT_MASK(32) previously. Meaning we do not reset the upper bits.
By using the dma_alloc_coherent_mask function - it does the proper casting
and we get 0xfffffffff.
This caused not working sound on a system with 4 GB and a 64-bit
compatible sound-card with sets the DMA-mask to 64bit.
On bare-metal and the forward-ported xen-dom0 patches from OpenSuse a coherent
DMA-memory is always allocated inside the 32-bit address-range by calling
dma_alloc_coherent_mask.
This patch adds the same functionality to xen swiotlb and is a rebase of the
original patch from Ronny Hegewald which never got upstream b/c the
underlaying reason was not understood until now.
The original email with the original patch is in:
