Re: [PATCH v2 0/3] Resolve -Wattribute-alias warnings from SYSCALL_DEFINEx()

2018-06-20 5:14 GMT+09:00 Paul Burton [off-list ref]:

This series introduces infrastructure allowing compiler diagnostics to
be disabled or their severity modified for specific pieces of code, with
suitable abstractions to prevent that code from becoming tied to a
specific compiler.

This infrastructure is then used to disable the -Wattribute-alias
warning around syscall definitions, which rely on type mismatches to
sanitize arguments.

Finally PowerPC-specific #pragma's are removed now that the generic code
is handling this.

The series takes Arnd's RFC patches & addresses the review comments they
received. The most notable effect of this series to to avoid warnings &
build failures caused by -Wattribute-alias when compiling the kernel
with GCC 8.

Applies cleanly atop v4.18-rc1.

Series, applied to linux-kbuild/fixes.
(since we need to fix warnings from GCC 8.1)


Thanks!
