hugepages using CMA: - Add arch_get_random_long() support. - Add ap bus userspace notifications. - Increase default size of vmalloc area to 512GB and otherwise let it increase dynamically by the size of physical memory. This should fix all occurrences where the vmalloc area was not large enough. - Completely get rid of set_fs() (aka select SET_FS) and rework address space handling while doing that; making address space handling much more simple. - Reimplement getcpu vdso syscall in C. - Add support for extended SCLP responses (> 4k). This allows e.g. to handle also potential large system configurations. - Simplify KASAN by removing 3-level page table support and only supporting 4-levels from now on. - Improve debug-ability of the kernel decompressor code, which now prints also stack traces and symbols in case of problems to the console. - Remove more power management leftovers. - Other various fixes and improvements all over the place. -----BEGIN PGP SIGNATURE----- iQIzBAABCAAdFiEECMNfWEw3SLnmiLkZIg7DeRspbsIFAl/XQAIACgkQIg7DeRsp bsIdYA//TCtSTrka/yW03b4b0FuLtKNpKB5zQgaqtEurbgbZhXdZ7/L3N+KavPQH njmKAARxebRIJB0DoZ9w9XpSb+mI3Q5y8GMi5xvUzjtJj/c6ahi3cEXIpuDR0PBv bf4UYSUpvndOwVFVOEZLeaJwKciCYvdoOwjBCmoKz9orthNVdVh5vztVRE2dMkNl y9C/Pb3w4ZMYxrbETuYnxqzueCxUhVOJmwodkGdP6bxBeemOwKn2TLVZQCbGGe7y BZpG+xsTaLZV1dZUZuDSOzVi1CTzJBGaJuYy5ewddWfxi7+mxqwEg/4s6nGKAciX Fa3T6aqLpUmDDN842Ql9TZHrwR+GYrlAp3XaQETOusUuEQLvP1dKRj/RXiDXN3MZ L+Mfa56dbs9GkVaNN/N+L7Y4z/6tZ2caX4X2S22Cp/QzvRTrG4jXVTn0r4WIcY/2 vn7fEy71LJ97CLQTDryyfJx7YNMdyIlUZY5ICAk1bt8nz1lB/IoZy0YoCBvPxIzb cEKcFTOdOtZR4WY3F8+kU0Nv1HQ8yPBzMaAqSNERvNQhMvoCChxntmyYxuVgH5iB SACADqEJKQ3hb4nMnxkeTrmmrhH4e0kdF9lAEytX+VYbjAq/6MY+qYo+QHDYkFWh BndxI54d6IiktDcKuBcpKJM7S/7N2t+EsLTS6Dhux7dbDZ2+Upw= =UR7j -----END PGP SIGNATURE----- Merge tag 's390-5.11-1' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux Pull s390 updates from Heiko Carstens: - Add support for the hugetlb_cma command line option to allocate gigantic hugepages using CMA - Add arch_get_random_long() support. - Add ap bus userspace notifications. - Increase default size of vmalloc area to 512GB and otherwise let it increase dynamically by the size of physical memory.
