Subject: perf annotate: Defer allocating sym_priv->hist array
X-Git-Tag: v2.6.34-rc1~197^2~20
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=628ada0cb03666dd463f7c25947eaccdf440c309;p=pandora-kernel.git

perf annotate: Defer allocating sym_priv->hist array

Because symbol->end is not fixed up at symbol_filter time, only
after all symbols for a DSO are loaded, and that, for asm
symbols, may be bogus, causing segfaults when hits happen in
these symbols.
