    Subject[PATCH AUTOSEL 4.14 078/108] x86/apic: Make TSC deadline timer detection message visible
    Date
    From: Borislav Petkov <bp@suse.de>

    [ Upstream commit de308d1815c9e8fe602a958c5c76142ff6501d75 ]

    The commit

    c84cb3735fd5 ("x86/apic: Move TSC deadline timer debug printk")

    removed the message which said that the deadline timer was enabled.
    It added a pr_debug() message which is issued when deadline timer
    validation succeeds.

    Well, issued only when CONFIG_DYNAMIC_DEBUG is enabled - otherwise
    pr_debug() calls get optimized away if DEBUG is not defined in the
    compilation unit.

    Therefore, make the above message pr_info() so that it is visible in
    dmesg.
