This board uses a P5020 chip, and boots just fine using the corenet_generic code. The device tree is very similar to the P5020DS, except that there is no Flash memory.

While the handling of fsl,pq3-gpio and fsl,mpc8572-gpio is done in the same driver and the two hardly differ, the latter controller needs a workaround for an erratum in the gpio_get callback.

When building against older kernel headers, currently the tm-syscall test fails to build because PPC_FEATURE2_HTM_NOSC is not defined. Tweak the test so that if PPC_FEATURE2_HTM_NOSC is not defined it still builds, but prints a warning at run time and marks the test as skipped. Signed-off-by: NMichael Ellerman <mpe@ellerman.id.au>

The paca display is already more than 24 lines, which can be problematic if you have an old school 80x24 terminal, or more likely you are on a virtual terminal which does not scroll for whatever reason. This patch adds a new command "#", which takes a single (hex) numeric argument: lines per page. It will cause the output of "dp" and "dpa" to be broken into pages, if necessary.

The pseries build with PCI=n looks to have been broken for at least 5 years, and no one's noticed or cared. Following the obvious breakages backward, the first commit I can find that builds is the parent of 2eb4afb6 ("powerpc/pci: Move pseries code into pseries platform specific area") from April 2009. A distro would never ship a PCI=n kernel, so it is only useful for folks building custom kernels. Also on KVM the virtio devices appear on PCI, so it would only be useful if you were building kernels specifically to run on PowerVM and with no PCI devices. The added code complexity, and testing load (which we've clearly not been doing), is not justified by the small reduction in kernel size for such a niche use case. So just make PCI non-optional on pseries. Signed-off-by: NMichael Ellerman <mpe@ellerman.id.au>

My recent commit d2036f30 ("scripts/kconfig/Makefile: Allow KBUILD_DEFCONFIG to be a target"), contained a bug in that when it checks if KBUILD_DEFCONFIG is a file it forgets to prepend $(srctree) to the path. This causes the build to fail when building out of tree (with O=), and when the value of KBUILD_DEFCONFIG is 'defconfig'. In that case we will fail to find the 'defconfig' file, because we look in the build directory not $(srctree), and so we will call Make again with 'defconfig' as the target. From there we loop infinitely calling 'make defconfig' again and again. The fix is simple, we need to look for the file under $(srctree).

We need to properly identify whether a hugepage is an explicit or a transparent hugepage in follow_huge_addr(). We used to depend on hugepage shift argument to do that. But in some case that can result in wrong results. For ex: On finding a transparent hugepage we set hugepage shift to PMD_SHIFT. But we can end up clearing the thp pte, via pmdp_huge_get_and_clear. We do prevent reusing the pfn page via the usage of kick_all_cpus_sync(). But that happens after we updated the pte to 0. Hence in follow_huge_addr() we can find hugepage shift set, but transparent huge page check fail for a thp pte. NOTE: We fixed a variant of this race against thp split in commit 691e95fd ("powerpc/mm/thp: Make page table walk safe against thp split/collapse") Without this patch, we may hit the BUG_ON(flags & FOLL_GET) in follow_page_mask occasionally.
