parisc: Replace regular spinlock with spin_trylock on panic path

2023-05-03T15:43:26Z

The panic notifiers' callbacks execute in an atomic context, with interrupts/preemption disabled, and all CPUs not running the panic function are off, so it's very dangerous to wait on a regular spinlock, there's a risk of deadlock. Refactor the panic notifier of parisc/power driver to make use of spin_trylock - for that, we've added a second version of the soft-power function. Also, some comments were reorganized and trailing white spaces, useless header inclusion and blank lines were removed. Cc: "James E.J.

Kconfig: introduce HAS_IOPORT option and select it as necessary

2023-04-05T20:15:19Z

We introduce a new HAS_IOPORT Kconfig option to indicate support for I/O Port access. In a future patch HAS_IOPORT=n will disable compilation of the I/O accessor functions inb()/outb() and friends on architectures which can not meaningfully support legacy I/O spaces such as s390. The following architectures do not select HAS_IOPORT: * ARC * C-SKY * Hexagon * Nios II * OpenRISC * s390 * User-Mode Linux * Xtensa All other architectures select HAS_IOPORT at least conditionally. The "depends on" relations on HAS_IOPORT in drivers as well as ifdefs for HAS_IOPORT specific sections will be added in subsequent patches on a per subsystem basis.

parisc: pdc_stable: use strscpy() to instead of strncpy()

2023-01-09T08:51:56Z

The implementation of strscpy() is more robust and safer. That's now the recommended way to copy NUL-terminated strings. Signed-off-by: Xu Panda Signed-off-by: Yang Yang Signed-off-by: Helge Deller
