mainlining shenanigans
1. During normal suspend (WoL not enabled) process, system has posibility to hang. The root cause is TXF interrupt coming after clocks disabled, system hang when accessing registers from interrupt handler. To fix this issue, disable all interrupts when system suspend. 2. System also has posibility to hang with WoL enabled during suspend, after entering stop mode, then magic pattern coming after clocks disabled, system will be waked up, and interrupt handler will be called, system hang when access registers. To fix this issue, disable wakeup irq in .suspend(), and enable it in .resume(). Signed-off-by: Joakim Zhang <qiangqing.zhang@nxp.com> Signed-off-by: David S. Miller <davem@davemloft.net> |

Linux kernel ============ There are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. Please read Documentation/admin-guide/README.rst first. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. The formatted documentation can also be read online at: https://www.kernel.org/doc/html/latest/ There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
