* Mitigates CVE-2021-0127, INTEL-SA-00532: an unexpected code breakpoint
may cause a system hang, on many processors.
* Mitigates CVE-2021-0145, INTEL-SA-00561: information disclosure due
to improper sanitization of shared resources (fast-store forward
predictor), on many processors.
* Mitigates CVE-2021-33120, INTEL-SA-00589: out-of-bounds read on some
Atom Processors may allow information disclosure or denial of service
via network access.
* Fixes critical errata (functional issues) on many processors
* Adds a MSR switch to enable RAPL filtering (default off, once enabled
it can only be disabled by poweroff or reboot). Useful to protect
SGX and other threads from side-channel info leak. Improves the
mitigation for CVE-2020-8694, CVE-2020-8695, INTEL-SA-00389 on many
processors.
* Disables TSX in more processor models.
* Fixes issue with WBINDV on multi-socket (server) systems which could
cause resets and unpredictable system behavior.
* Adds a MSR switch to 10th and 11th-gen (Ice Lake, Tiger Lake, Rocket
Lake) processors, to control a fix for (hopefully rare) unpredictable
processor behavior when HyperThreading is enabled. This MSR switch
is enabled by default on *server* processors. On other processors,
it needs to be explicitly enabled by an updated UEFI/BIOS (with added
configuration logic). An updated operating system kernel might also
be able to enable it. When enabled, this fix can impact performance.

sig 0x00080665, pf_mask 0x01, 2021-02-17, rev 0xb00000f, size 130048
* update .gitignore and debian/.gitignore.
Add some missing items from .gitignore and debian/.gitignore.
* ucode-blacklist: do not late-load 0x406e3 and 0x506e3.
When the BIOS microcode is older than revision 0x7f (and perhaps in some
other cases as well), the latest microcode updates for 0x406e3 and
0x506e3 must be applied using the early update method. Otherwise, the
system might hang. Also: there must not be any other intermediate
microcode update attempts [other than the one done by the BIOS itself],
either. It must go from the BIOS microcode update directly to the
latest microcode update.
* source: update symlinks to reflect id of the latest release, 20220207
