latest sparse warnings with latest kernel

latest sparse warnings with latest kernel

[Russell King]

Hi,

I'm seeing a lot of the following warnings when building the latest
-git kernel with the latest sparse checker:

/usr/local/lib/gcc-lib/arm-linux/3.3/include/stdarg.h:54:9: warning: preprocessor token va_copy redefined
/home/rmk/git/linux-2.6-rmk/include/linux/compiler-gcc2.h:29:9: this was the original definition

Since sparse pretends to be a gcc 2.95 compiler, should it really
be using the gcc 3.3 header files?

Shouldn't it provide its own headers to correspond with the version
it pretends to be? 8)

Yes, but it should pretend to be 3.x.  See tarball on parcelfarce; I'll
send the patches to Linus.

No.
