| "value": "mm/memory_hotplug: fix memmap_on_memory sysfs value retrieval\n\ncommit 11684134140bb708b6e6de969a060535630b1b53 upstream.\n\nset_memmap_mode() stores the kernel parameter memmap mode as an integer.\nHowever, the get_memmap_mode() function utilizes param_get_bool() to fetch\nthe value as a boolean, leading to potential endianness issue. On\nBig-endian architectures, the memmap_on_memory is consistently displayed\nas 'N' regardless of its actual status.\n\nTo address this endianness problem, the solution involves obtaining the\nmode as an integer. This adjustment ensures the proper display of the\nmemmap_on_memory parameter, presenting it as one of the following options:\nForce, Y, or N.\n\nLink: https://lkml.kernel.org/r/20240110140127.241451-1-sumanthk@linux.ibm.com\nFixes: 2d1f649c7c08 (\"mm/memory_hotplug: support memmap_on_memory when memmap is not aligned to pageblocks\")\nSigned-off-by: Sumanth Korikkar <sumanthk@linux.ibm.com>\nSuggested-by: Gerald Schaefer <gerald.schaefer@linux.ibm.com>\nAcked-by: David Hildenbrand <david@redhat.com>\nCc: Alexander Gordeev <agordeev@linux.ibm.com>\nCc: Aneesh Kumar K.V <aneesh.kumar@linux.ibm.com>\nCc: Heiko Carstens <hca@linux.ibm.com>\nCc: Michal Hocko <mhocko@suse.com>\nCc: Oscar Salvador <osalvador@suse.de>\nCc: Vasily Gorbik <gor@linux.ibm.com>\nCc: <stable@vger.kernel.org>\t[6.6+]\nSigned-off-by: Andrew Morton <akpm@linux-foundation.org>\nSigned-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>" |
