  "message": "x86: Cleanup highmap after brk is concluded\n\nNow cleanup_highmap actually is in two steps: one is early in head64.c\nand only clears above _end; a second one is in init_memory_mapping() and\ntries to clean from _brk_end to _end.\nIt should check if those boundaries are PMD_SIZE aligned but currently\ndoes not.\nAlso init_memory_mapping() is called several times for numa or memory\nhotplug, so we really should not handle initial kernel mappings there.\n\nThis patch moves cleanup_highmap() down after _brk_end is settled so\nwe can do everything in one step.\nAlso we honor max_pfn_mapped in the implementation of cleanup_highmap.\n\nSigned-off-by: Yinghai Lu \u003cyinghai@kernel.org\u003e\nSigned-off-by: Stefano Stabellini \u003cstefano.stabellini@eu.citrix.com\u003e\nLKML-Reference: \u003calpine.DEB.2.00.1103171739050.3382@kaball-desktop\u003e\nSigned-off-by: H.
