No change to default behavior. Replace the hard-coded mdelay(10) in cpu_up() with a variable udelay, that is set to a defined default -- rather than a magic number.

Software optimization guides for both F15h and F16h cite those NOPs as the optimal ones. A microbenchmark confirms that actually even older families are better with the single-insn NOPs so switch to them for the alternatives. Cycles count below includes the loop overhead of the measurement but that overhead is the same with all runs.

The following commit: f893959b ("x86/fpu: Don't abuse drop_init_fpu() in flush_thread()") removed drop_init_fpu() usage from flush_thread(). This seems to break things for me - the Go 1.4 test suite fails all over the place with floating point comparision errors (offending commit found through bisection). The functional change was that flush_thread() after this commit only calls restore_init_xstate() when both use_eager_fpu() and !used_math() are true. drop_init_fpu() (now fpu_reset_state()) calls restore_init_xstate() regardless of whether current used_math() - apply the same logic here. Switch used_math() -> tsk_used_math(tsk) to consistently use the grabbed tsk instead of current, like in the rest of flush_thread().

Remove the per-CPU delays during SMP initialization, which seems to be possible on newer architectures with an x2APIC. Xen does this since 2011. In fact, this commit is basically a combination of the following Xen commits. The first removes the delays, the second fixes an issue with the removal: commit 68fce206f6dba9981e8322269db49692c95ce250 Author: Tim Deegan <Tim.Deegan@citrix.com> Date: Tue Jul 19 14:13:01 2011 +0100 x86: Remove timeouts from INIT-SIPI-SIPI sequence when using x2apic. Some of the timeouts are pointless since they're waiting for the ICR to ack the IPI delivery and that doesn't happen on x2apic. The others should be benign (and are suggested in the SDM) but removing them makes AP bringup much more reliable on some test boxes.

Commit 75182b16 ("x86/asm/entry: Switch all C consumers of kernel_stack to this_cpu_sp0()") changed current_thread_info to use this_cpu_sp0, and indirectly made it rely on init_tss which was exported with EXPORT_PER_CPU_SYMBOL_GPL. As a result some macros and inline functions such as set/get_fs, test_thread_flag and variants have been made unusable for external modules. Make cpu_tss exported with EXPORT_PER_CPU_SYMBOL so that these functions are accessible again, as they were previously.

Commit 61f01dd9 ("x86_64, asm: Work around AMD SYSRET SS descriptor attribute issue") makes AMD processors set SS to __KERNEL_DS in __switch_to() to deal with cases when SS is NULL. This breaks Xen PV guests who do not want to load SS with__KERNEL_DS. Since the problem that the commit is trying to address would have to be fixed in the hypervisor (if it in fact exists under Xen) there is no reason to set X86_BUG_SYSRET_SS_ATTRS flag for PV VPCUs here. This can be easily achieved by adding x86_hyper_xen_hvm.set_cpu_features op which will clear this flag. (And since this structure is no longer HVM-specific we should do some renaming).

This reverts commits 0a4e6be9 and 80f7fdb1. The task migration notifier was originally introduced in order to support the pvclock vsyscall with non-synchronized TSC, but KVM only supports it with synchronized TSC. Hence, on KVM the race condition is only needed due to a bad implementation on the host side, and even then it's so rare that it's mostly theoretical. As far as KVM is concerned it's possible to fix the host, avoiding the additional complexity in the vDSO and the (re)introduction of the task migration notifier. Xen, on the other hand, hasn't yet implemented vsyscall support at all, so we do not care about its plans for non-synchronized TSC.

AMD CPUs don't reinitialize the SS descriptor on SYSRET, so SYSRET with SS == 0 results in an invalid usermode state in which SS is apparently equal to __USER_DS but causes #SS if used.
