Subject: x86/dumpstack: Fix duplicate RIP address display in __show_regs()
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=1141c3e39c64e4aba2d98cb3dcca95369c9dafbe;p=openwrt%2Fstaging%2Fblogic.git

x86/dumpstack: Fix duplicate RIP address display in __show_regs()

The RIP address is shown twice in __show_regs().  Before:

  RIP: 0010:[<ffffffff81070446>]  [<ffffffff81070446>] native_write_msr+0x6/0x30

After:

  RIP: 0010:[<ffffffff81070446>] native_write_msr+0x6/0x30
