Additionally since we are reading a recovery request from H1 it
needs to cache the result since H1 will only return true on the

recovery. Add a CAR global here to keep track of the state and

Some CPUs, (Intel core2 and pineview) have slightly different SMRR
MTRR mechanism. The MSR_SMRR_PHYSBASE/MASK MSRs are at a different
location, have slightly different semantics and need SMRR enable in a
locked down IA32_FEATURE_CONTROL MSR.
This change takes away the possibility to (not) lock
IA32_FEATURE_CONTROL on these CPUs, as this is needed for SMRR MSR to
work. Since sockets cover multiple CPUs of which only some support
SMRR, the Kconfig option CONFIG_SET_IA32_FC_LOCK_BIT is kept in place,
even though it gets meaningless on those CPUs. Locking that bit was
the default anyway.
With this patch Intel Netburst CPUs also configure
IA32_FEATURE_CONTROL. According to Intel 64 and IA-32 Architectures
Software Developer's Manual those CPUs support that MSR so issues are
not to be expected.
