[PATCH v2] sched_ext: Use kvzalloc for large exit_dump allocation

by Breno Leitao

Replace kzalloc with kvzalloc for the exit_dump buffer allocation, which can require large contiguous memory (up to order=9) depending on the implementation. This change prevents allocation failures by allowing the system to fall back to vmalloc when contiguous memory allocation fails. Since this buffer is only used for debugging purposes, physical memory contiguity is not required, making vmalloc a suitable alternative.

[PATCH 2/6] bus: fsl-mc: do not add a device-link for the UAPI used DPMCP device

by Ioana Ciornei

The fsl-mc bus associated to the root DPRC in a DPAA2 system exports a device file for userspace access to the MC firmware. In case the DPRC's local MC portal (DPMCP) is currently in use, a new DPMCP device is allocated through the fsl_mc_portal_allocate() function. In this case, the call to fsl_mc_portal_allocate() will fail with -EINVAL when trying to add a device link between the root DPRC (consumer) and the newly allocated DPMCP device (supplier). This is because the DPMCP is a dependent of the DPRC device (the bus). Fix this by not adding a device link in case the DPMCP is allocated for the root DPRC's usage.
