-Subject: [PATCH 10/20] Add option to automatically enforce module signatures
- when in Secure Boot mode
-
-UEFI Secure Boot provides a mechanism for ensuring that the firmware will
-only load signed bootloaders and kernels. Certain use cases may also
-require that all kernel modules also be signed. Add a configuration option
-that enforces this automatically when enabled.

-Subject: [PATCH 12/20] efi: Disable secure boot if shim is in insecure mode
-
-A user can manually tell the shim boot loader to disable validation of
-images it loads. When a user does this, it creates a UEFI variable called
-MokSBState that does not have the runtime attribute set. Given that the
-user explicitly disabled validation, we can honor that and not enable
-secure boot mode if that variable is set.

-The upcoming GCC 9 release adds the -Wmissing-attributes warnings
-(enabled by -Wall), which trigger for all the init/cleanup_module
-aliases in the kernel (defined by the module_init/exit macros),
-ending up being very noisy.
-
-These aliases point to the __init/__exit functions of a module,
-which are defined as __cold (among other attributes). However,
-the aliases themselves do not have the __cold attribute.
-
-Since the compiler behaves differently when compiling a __cold
-function as well as when compiling paths leading to calls
-to __cold functions, the warning is trying to point out
-the possibly-forgotten attribute in the alias.
-
-In order to keep the warning enabled, we choose to silence
-the warning by marking the aliases as __cold. This is possible
-marking either the extern declaration, the definition, or both.
-In order to avoid changing the behavior of callers, we do it
-only in the definition of the aliases (since those are not
-seen by any other TU).

----
-Note that an alternative is using the new copy attribute
-introduced by GCC 9 (Martin told me about it, as well as the
-new warning).
-
-What I am concerned about using __copy is that I am not sure
-we should be copying all the attributes (even if some are
-blacklisted by the copy itself), since:
- - We have unknown-to-GCC attributes (e.g. from plugins).
- - We wouldn't enjoy the fix for older compilers
- (e.g. if the fix had an actual impact).
-
-So here I took the conservative approach for the moment,
-and we can discuss/apply whether another solution is best.
-
-Jessica: please review what I explain in the commit message.
-Do we actually want the __cold attribute in the declaration
-as well? If yes, AFAIK, GCC would assume paths that end up
-calling the __init/__exit functions are not meant to be taken
-(but when we are asked to load modules, that is the expected
-path, no?).
-
-I will put this in the compiler-attributes tree and get
-some time in linux-next, unless you want to pick it up!

-The upcoming GCC 9 release extends the -Wmissing-attributes warnings
-(enabled by -Wall) to C and aliases: it warns when particular function
-attributes are missing in the aliases but not in their target.
-
-In particular, it triggers here because crc32_le_base/__crc32c_le_base
-aren't __pure while their target crc32_le/__crc32c_le are.
-
-These aliases are used by architectures as a fallback in accelerated
-versions of CRC32. See commit 9784d82db3eb ("lib/crc32: make core crc32()
-routines weak so they can be overridden").
-
-Therefore, being fallbacks, it is likely that even if the aliases
-were called from C, there wouldn't be any optimizations possible.
-Currently, the only user is arm64, which calls this from asm.
-
-Still, marking the aliases as __pure makes sense and is a good idea
-for documentation purposes and possible future optimizations,
-which also silences the warning.

-I am picking this up through the compiler-attributes tree
-and putting it into -next along with the other cleanup
-for -Wmissing-attributes (unless some other maintainer wants it).
