| git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux Pull powerpc updates from Michael Ellerman: - Enable KFENCE for 32-bit. - Implement EBPF for 32-bit. - Convert 32-bit to do interrupt entry/exit in C. - Convert 64-bit BookE to do interrupt entry/exit in C. - Changes to our signal handling code to use user_access_begin/end() more extensively. - Add support for time namespaces (CONFIG_TIME_NS) - A series of fixes that allow us to reenable STRICT_KERNEL_RWX. - Other smaller features, fixes & cleanups.

| 2021-04-14 | powerpc/papr_scm: Implement support for H_SCM_FLUSH hcall | Shivaprasad G Bhat | 1 | -0/+14 | |
| Add support for ND_REGION_ASYNC capability if the device tree indicates 'ibm,hcall-flush-required' property in the NVDIMM node. Flush is done by issuing H_SCM_FLUSH hcall to the hypervisor. If the flush request failed, the hypervisor is expected to to reflect the problem in the subsequent nvdimm H_SCM_HEALTH call. This patch prevents mmap of namespaces with MAP_SYNC flag if the nvdimm requires an explicit flush[1].

| 2020-01-29 | powerpc: Provide initial documentation for PAPR hcalls | Vaibhav Jain | 1 | -0/+250 | |
| This doc patch provides an initial description of the hcall op-codes that are used by Linux kernel running as a guest (LPAR) on top of PowerVM or any other sPAPR compliant hyper-visor (e.g qemu). Apart from documenting the hcalls the doc-patch also provides a rudimentary overview of how hcall ABI, how they are issued with the Linux kernel and how information/control flows between the guest and hypervisor.
