parisc: Do not reprogram affinitiy on ASP chip

2026-01-08T09:14:21+00:00

commit dca7da244349eef4d78527cafc0bf80816b261f5 upstream. The ASP chip is a very old variant of the GSP chip and is used e.g. in HP 730 workstations. When trying to reprogram the affinity it will crash with a HPMC as the relevant registers don't seem to be at the usual location. Let's avoid the crash by checking the sversion. Also note, that reprogramming isn't necessary either, as the HP730 is a just a single-CPU machine. Signed-off-by: Helge Deller Cc: stable@vger.kernel.org Signed-off-by: Greg Kroah-Hartman

parisc: pdc_stable: Constify struct kobj_type

2024-09-09T06:53:17+00:00

This 'struct kobj_type' is not modified. It is only used in kobject_init_and_add() which takes a 'const struct kobj_type *ktype' parameter. Constifying this structure and moving it to a read-only section, and can increase over all security. Signed-off-by: Hongbo Li Signed-off-by: Helge Deller

change alloc_pages name in dma_map_ops to avoid name conflicts

2024-04-26T03:55:53+00:00

After redefining alloc_pages, all uses of that name are being replaced. Change the conflicting names to prevent preprocessor from replacing them when it's not intended.

parisc: led: Convert to platform remove callback returning void

2024-03-08T09:00:07+00:00

The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is ignored (apart from emitting a warning) and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new(), which already returns void. Eventually after all drivers are converted, .remove_new() will be renamed to .remove(). Trivially convert this driver from always returning zero in the remove callback to the void returning variant. Signed-off-by: Uwe Kleine-König Signed-off-by: Helge Deller

parisc/power: Fix power soft-off button emulation on qemu

2024-01-07T21:59:16+00:00

Make sure to start the kthread to check the power button on qemu as well if the power button address was provided. This fixes the qemu built-in system_powerdown runtime command.
