Subject[ 01/42] Perf: fix build breakage
3.0-stable review patch.  If anyone has any objections, please let me know.

------------------


From: Zeev Tarantov <zeev.tarantov@gmail.com>

[Patch not needed upstream as this is a backport build bugfix - gregkh

gcc correctly complains:

util/hist.c: In function ‘__hists__add_entry’:
util/hist.c:240:27: error: invalid type argument of ‘->’ (have ‘struct hist_entry’)
util/hist.c:241:23: error: invalid type argument of ‘->’ (have ‘struct hist_entry’)

for this new code:

+ if (he->ms.map != entry->ms.map) {
+ he->ms.map = entry->ms.map;
+ if (he->ms.map)
+ he->ms.map->referenced = true;
+ }

because "entry" is a "struct hist_entry", not a pointer to a struct.

In mainline, "entry" is a pointer to struct passed as argument to the function.
So this is broken during backporting. But obviously not compile tested.
