Paging Writeable depends on EPT, so must disabled in non-EPT guests like the
other EPT dependent features. Otherwise, VMEntry fails with bad control
state.
Drop a piece of trailing whitepsace in context.

Print the CPU and APIC ID that fails to respond to the init sequence, or
that didn't manage to reach the "callin" state. Expand a bit the printed
error messages. Otherwise the "Not responding." message is not easy to
understand by users.

Hello,
This series attempts to improve AP boot failure diagnosis by improving
the printed failure messages (patch 1) and detecting AP getting stuck
during bringup (patch 3). Patch 2 is preparatory changes for the work
done in patch 3.
They should be non-functional changes for systems working cor
With the current AP bring up code, Xen can get stuck indefinitely if an AP
freezes during boot after the 'callin' step. Introduce a 5s timeout while
waiting for APs to finish startup.
On failure of an AP to complete startup, send an NMI to trigger the
printing of a stack backtrace on the stuck AP
Split the code that triggers remote CPUs to dump stacks into a separate
function. Also introduce a parameter that can be set by the caller of the
newly introduced function to force CPUs to dump the full stack, rather than
just dumping the current function name.
No functional change intended.
