Building the kernel with newer Clang versions triggers
-Wdefault-const-init-var-unsafe in the typecheck() macro:
error: default initialization of an object of type 'const unsigned long'
leaves the object uninitialized [-Wdefault-const-init-var-unsafe]
The warning originates from the following declaration in typecheck():
typeof(x) __dummy2;
When 'x' has a const-qualified type (e.g. 'const unsigned long'),
Clang warns that the variable is declared const but not initialized.
With -Werror enabled this causes the build to fail.
Initialize the temporary variable to zero to silence the warning:
typeof(x) __dummy2 = (typeof(x))0;
This variable is only used for compile-time type checking and its
value is never read, so the initialization has no functional impact
on the generated code.
Fixes: e0deaff47090 ("split the typecheck macros out of include/linux/kernel.h")

As you can see from the build reports, this does not work. Are you
missing commit d0afcfeb9e38 ("kbuild: Disable
-Wdefault-const-init-unsafe") in your tree? Or does this appear in
somewhere that uses its own KBUILD_CFLAGS, in which case a fix like
5ba35a6c13ff ("s390/boot: Add -Wno-default-const-init-unsafe to KBUILD_CFLAGS")
b4780fe4ddf0 ("s390/purgatory: Add -Wno-default-const-init-unsafe to KBUILD_CFLAGS")
will be needed? I do not see any instances of this warning in Linus's
tree unless I am missing some configuration in my build tests.
Cheers,
Nathan
