Subject: x86: remove volatile keyword from clflush.
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=e34907ae180f4fe6c28bb4516c679c2f81b0c9ed;p=GitHub%2FLineageOS%2Fandroid_kernel_samsung_universal7580.git

x86: remove volatile keyword from clflush.

the p parameter is an explicit memory reference, and is
enough to prevent gcc to being nasty here. The volatile
seems completely not needed.
