Subject: x86: pageattr-test: remove srandom32 call
X-Git-Tag: next-20130322~1^2~72
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=0b07d0eefb9ee5c533e5924348721beb740ad85e;p=karo-tx-linux.git

x86: pageattr-test: remove srandom32 call

pageattr-test calls srandom32() once every test iteration.  But calling
srandom32() after late_initcalls is not meaningfull.  Because the random
states for random32() is mixed by good random numbers in late_initcall
prandom_reseed().

So this removes the call to srandom32().
