Subject: x86, ds: fix bad ds_reset_pebs()
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=608780a9048efa3e85fbc4d8649b26805cc588aa;p=linux-beck.git

x86, ds: fix bad ds_reset_pebs()

Ds_reset_pebs() passed the wrong qualifier to a shared function resulting
in a reset of bts, rather than pebs.
