Hi Boris,

Apologies for the delayed response. I somehow managed to lose updates on
this thread.

Although simple, won't it make the already convoluted code flow more
so. Instead in addition to not setting hest_disable when the table is
not found ...

... would you be open to a patch re-working the ghes driver
initialisation to only do the platform driver registration. The the rest
of the initialisation (including the apei_osc_setup and related
messages) can be performed when the first ghes device gets probed.

Does that sound like a better alternative?
