[PATCH v2 0/4] libstub,tpm: fix small bugs and improve error reporting

[Gregory Price]

The efi/tpm code has a number of small signed/unsigned bugs and
inaccuracies are prone to cause further bugs in a difficult to
debug manner.  For example, there is a signed/unsigned mismatch
in efi/tpm.c that can lead to calling memblock_reserve on a range
with an effectively negative length.

Additionally, there are silently ignored error conditions may
result in undefined behavior.  Address these.
