* Unless and until the core mm handles memory hotplug units smaller than a section (128M), persistent memory namespaces must be padded to section alignment. The libnvdimm core already handled section collision with "System RAM", but some configurations overlap independent "Persistent Memory" ranges within a section, so additional padding injection is added for that case. * The recent reworks of the ARS (address range scrub) state machine to reduce the number of state flags inadvertantly missed a conversion of acpi_nfit_ars_rescan() call sites. Fix the regression whereby user-requested ARS results in a "short" scrub rather than a "long" scrub. * Fixup the unit tests to handle / test the 128M section alignment of mocked test resources. -----BEGIN PGP SIGNATURE----- iQIcBAABAgAGBQJcDK/gAAoJEB7SkWpmfYgCCDsP/3VYrJfJwDVMGbvR4DX4P9WT vmft+ac++0aKId+Ei80GwENAQbMttmQ1woHTGAJpEt+A3AL8DWFSFQiqW0b+/eAg DW60dYN2cO0M6jkkJyIUMaWRy3iT7OOfEXLlJOubL7EnbivczjZFOAElvdpzPaK0 +zIStgCdvmdcnZMi0BIst5XLoZ4/wWrR0Caq+ULpHoeDSO/oz3I2HV5gvxPE/7sJ WXSdB8zbLSS67fzFik1FJbbRRzEfBH7RJpgMoMpDLT3HtwcMvMrV8iJgNApccueV pFGhb5BpaJLaLc59RYxxVp/vLBEEaWDxq54RzU4twf4mbI1sc/NKJ08Nkwo9l8lH I6CW3FvegYzMkHD8PNd32GAr9HIxktvlH4Hc1GzaSSWwyeKx+5Et4llDpuuqW19o +wlybxRzZEoRNacwnxk1FPeOYUPPKLogkVOf14umh10tvi4UIuGkophoO1bxXc4d 2gDPAHr3G1hAz+JV7PW/L+rO43uL8MWBYLdZgLiQ+90OAURu7e/f06j2SWzyHV1S 9AajUqqLLV3whXHUfpl50Eymml9dEyw9NfbKOkry88Kde1NrwC/ccGB/90nKLoa+ A2HxroRgxk8my8HXztnxLbhuxk0dnV4jK9v2mm9lGS6IUSWL6tePzneA8gGM2tYm rt2gaqY2bFOOSmG56Uac =85/B -----END PGP SIGNATURE----- Merge tag 'libnvdimm-fixes-4.20-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm Pull libnvdimm fixes from Dan Williams: "A regression fix for the Address Range Scrub implementation, yes another one, and support for platforms that misalign persistent memory relative to the Linux memory hotplug section constraint. Longer term, support for sub-section memory hotplug would alleviate alignment waste, but until then this hack allows a 'struct page' memmap to be established for these misaligned memory regions. These have all appeared in a -next release, and thanks to Patrick for reporting and testing the alignment padding fix. Summary: - Unless and until the core mm handles memory hotplug units smaller than a section (128M), persistent memory namespaces must be padded to section alignment. The libnvdimm core already handled section collision with "System RAM", but some configurations overlap independent "Persistent Memory" ranges within a section, so additional padding injection is added for that case. - The recent reworks of the ARS (address range scrub) state machine to reduce the number of state flags inadvertantly missed a conversion of acpi_nfit_ars_rescan() call sites. Fix the regression whereby user-requested ARS results in a "short" scrub rather than a "long" scrub. - Fixup the unit tests to handle / test the 128M section alignment of mocked test resources. * tag 'libnvdimm-fixes-4.20-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm: acpi/nfit: Fix user-initiated ARS to be "ARS-long" rather than "ARS-short" libnvdimm, pfn: Pad pfn namespaces relative to other regions tools/testing/nvdimm: Align test resources to 128M |
