Without DT aliases, the numbering of mmc interfaces is unpredictable. Adding them makes it possible to refer to devices consistently. The popular suggestion to use UUIDs obviously doesn't work with a blank device fresh from the factory.
See commit fa2d0aa96941 ("mmc: core: Allow setting slot index via device tree alias") for more discussion.

pxa168_eth_remove() firstly calls unregister_netdev(), then cancels a timeout work. unregister_netdev() shuts down a device interface and removes it from the kernel tables. If the timeout occurs in parallel, the timeout work (pxa168_eth_tx_timeout_task) performs stop and open of the device. It may lead to an inconsistent state and memory leaks.

While passing the A530-specific lm_setup func to A530 and A540 to !A530 was fine back when only these two were supported, it certainly is not a good idea to send A540 specifics to smaller GPUs like A508 and friends.

We have seen a couple cases where low memory situations cause something bad to happen, followed by a flood of these messages obscuring the root cause. Lets ratelimit the dmesg spam so that next time it happens we don't lose the kernel traces leading up to this.

[ Upstream commit 3d677f12ea3a2097a16ded570623567403dea959 ]
On many recent ThinkPad laptops, there's a new LED next to the ESC key, that indicates the FnLock status. When the Fn+ESC combo is pressed, FnLock is toggled, which causes the Media Key functionality to change, making it so that the media keys either perform their media key function, or function as an F-key by default. The Fn key can be used the access the alternate function at any time.
With the current linux kernel, the LED doens't change state if you press the Fn+ESC key combo. However, the media key functionality *does* change. This is annoying, since the LED will stay on if it was on during bootup, and it makes it hard to keep track what the current state of the FnLock is.
This patch calls an ACPI function, that gets the current media key state, when the Fn+ESC key combo is pressed. Through testing it was discovered that this function causes the LED to update correctly to reflect the current state when this function is called.
The relevant ACPI calls are the following: _SB_.PCI0.LPC0.EC0_.HKEY.GMKS: Get media key state, returns 0x603 if the FnLock mode is enabled, and 0x602 if it's disabled. _SB_.PCI0.LPC0.EC0_.HKEY.SMKS: Set media key state, sending a 1 will enable FnLock mode, and a 0 will disable it.

RHBZ: 1933527
Under SMB1 + POSIX, if an inode is reused on a server after we have read and cached a part of a file, when we then open the new file with the re-cycled inode there is a chance that we may serve the old data out of cache to the application. This only happens for SMB1 (deprecated) and when posix are used. The simplest solution to avoid this race is to force a revalidate on smb1-posix open.

Make SMB2 not print out an error when an oplock break is received for an unknown handle, similar to SMB1. The debug message which is printed for these unknown handles may also be misleading, so fix that too.
The SMB2 lease break path is not affected by this patch.
