powerpc/iommu: Add missing of_node_put in iommu_init_early_dart

2022-05-22T05:58:31Z

The device_node pointer is returned by of_find_compatible_node with refcount incremented. We should use of_node_put() to avoid the refcount leak. Signed-off-by: Peng Wu Signed-off-by: Michael Ellerman Link: https://lore.kernel.org/r/20220425081245.21705-1-wupeng58@huawei.com

powerpc/kasan: Disable address sanitization in kexec paths

2022-05-22T05:58:29Z

The kexec code paths involve code that necessarily run in real mode, as CPUs are disabled and control is transferred to the new kernel. Disable address sanitization for the kexec code and the functions called in real mode on CPUs being disabled.

powerpc: Add missing headers

2022-05-08T12:15:40Z

Don't inherit headers "by chances" from asm/prom.h, asm/mpc52xx.h, asm/pci.h etc... Include the needed headers, and remove asm/prom.h when it was needed exclusively for pulling necessary headers.
