Believe it or not there\nare a few of these happening during early boot.\n\nNext, we can\u0027t just drop to a memcpy() call in the forward copy case\nwhere dst \u003c\u003d src. The reason is that the cache initializing stores\nused in the Niagara memcpy() implementations can end up clearing out\ncache lines before we\u0027ve sourced their original contents completely.\n\nFor example, considering NG4memcpy, the main unrolled loop begins like\nthis:\n\n load src + 0x00\n load src + 0x08\n load src + 0x10\n load src + 0x18\n load src + 0x20\n store dst + 0x00\n\nAssume dst is 64 byte aligned and let\u0027s say that dst is src - 8 for\nthis memcpy() call. That store at the end there is the one to the\nfirst line in the cache line, thus clearing the whole line, which thus\nclobbers \"src + 0x28\" before it even gets loaded.\n\nTo avoid this, just fall through to a simple copy only mildly\noptimized for the case where src and dst are 8 byte aligned and the\nlength is a multiple of 8 as well. We could get fancy and call\nGENmemcpy() but this is good enough for how this thing is actually\nused.\n\nReported-by: David Ahern \u003cdavid.ahern@oracle.com\u003e\nReported-by: Bob Picco \u003cbpicco@meloft.net\u003e\nSigned-off-by: David S.

This\npreallocated pmd can never be freed - pmd_free does nothing when it is\ncalled with this pmd. When the kernel attempts to free this preallocated\npmd, it decreases the count of allocated pmds. The result is that the\ncounter underflows and this error is reported.\n\nThis patch fixes the bug by artifically incrementing the counter in\npmd_free when the kernel tries to free the preallocated pmd.\n\nSigned-off-by: Mikulas Patocka \u003cmpatocka@redhat.com\u003e\nAcked-by: Kirill A.
