Machine is sparc64, bk of today, gcc-3.4.2-6.fc3 (Aurora Corona). First 2.6
I try to build here, so it might be something known.
Build fails due to -Werror with:
include/asm/uaccess.h: In function `load_elf_binary':
arch/sparc64/kernel/../../../fs/binfmt_elf.c:811: warning: ignoring return
value of `__clear_user', declared with attribute warn_unused_result
Around line 811 of fs/binfmt_elf.c I see:
/*
* This bss-zeroing can fail if the ELF file
* specifies odd protections. So we don't check
* the return value
*/
(void)clear_user((void __user *)elf_bss +
load_bias, nbyte);
so presumably this discarding is OK here...
I wonder why an explicit (void) cast is not considered "use" by the
compiler. But then again, explicitly throwing away isn't really "use"...
