Hi All
on my amd64 profile i cannot disable PARAVIRT option.
even if i disable all i still get in my .config:
# CONFIG_X86_ES7000 is not set
# CONFIG_X86_RDC321X is not set
CONFIG_X86_VSMP=y
# CONFIG_PARAVIRT_GUEST is not set
CONFIG_PARAVIRT=y <<<<-------------------------------- issue
# CONFIG_MEMTEST_BOOTPARAM is not set
# CONFIG_M386 is not set
how to disable it? i guess it's a config bug.
CC me i'm not subscribed.

Nope. You have CONFIG_X86_VSMP enabled, which selects PARAVIRT:
config X86_VSMP
bool "Support for ScaleMP vSMP"
select PARAVIRT
depends on X86_64

Yes.

As Randy pointed out, VSMP selects PARAVIRT. VSMP does something
strange with AC in rflags and interrupt enable/disable, and so hooks the
appropriate pvops to implement it.
What's your underlying concern about PARAVIRT?
