ba0593bf553c450a03dbc5f8c1f0ff58b778a0c8 cleared the aforementioned
cpuid bit only on 32-bit due to various problems with Virtual PC. This
somehow got lost during the 32- + 64-bit merge so restore the feature
bit on 64-bit. For that, set it explicitly for non-constant arguments of
cpu_has(). Update comment for future reference.

After uncapping the CPUID level, we need to also re-run the CPU
feature detection code.

This resolves kernel bugzilla 16322.

At least on Intel, adjusting the max CPUID level can expose new CPUID
features, so we need to re-run get_cpu_cap() after changing the CPUID
level.

boot_cpu_id is there for historical reasons and was renamed to
boot_cpu_physical_apicid in patch:

 c70dcb7 x86: change boot_cpu_id to boot_cpu_physical_apicid

However, there are some remaining occurrences of boot_cpu_id that are
never touched in the kernel and thus its value is always 0.

This patch removes boot_cpu_id completely.
