The nps_enet driver happily mixes virtual, physical and __iomem
addresses, which are all different depending on the architecture

The knav_qmss driver is currently broken when CONFIG_LPAE is

Move the jump-label from sock_update_memcg() and sock_release_memcg()
to the callsite, and so eliminate those function calls when socket
accounting is not enabled.
This also eliminates the need for dummy functions because the calls
will be optimized away if the Kconfig options are not enabled.

When a cgroup currently breaches its socket memory limit, it enters

This watchdog is instantiated in a FPGA that is memory mapped. It is
made of only one register, called the feed register. Writing to this
register will re-arm the watchdog for a given time (and enable it if it
was disable). It can be disabled by writing a special value into it.

This fix alters the ordering of the IRQ and device registrations in the RTC
driver probe function. This change will apply to the RTC driver that supports
both DA9063 and DA9062 PMICs.
A problem could occur with the existing RTC driver if:

This device tree adds support for TS-4800 by Technologic Systems. This
board is based on MX51-babbage, but there are some subtle differences in
the pins used, and there is an additional FPGA that is memory-mapped.
