"extern inline" generates a warning with -Wmissing-prototypes and I'm currently working on getting the kernel cleaned up for adding this to the CFLAGS since it will help us to avoid a nasty class of runtime errors. If there are places that really need a forced inline, __always_inline would be the correct solution. Signed-off-by: NAdrian Bunk <bunk@stusta.de> Signed-off-by: NPaul Mackerras <paulus@samba.org>

We have a case where __get_user and __put_user can validly be used on kernel addresses in interrupt context - namely, the alignment exception handler, as our get/put_unaligned just do a single access and rely on the alignment exception handler to fix things up in the rare cases where the cpu can't handle it in hardware. Thus we can get alignment exceptions in the network stack at interrupt level. The alignment exception handler does a __get_user to read the instruction and blows up in might_sleep(). Since a __get_user on a kernel address won't actually ever sleep, this makes the might_sleep conditional on the address being less than PAGE_OFFSET. Signed-off-by: NPaul Mackerras <paulus@samba.org>

This patch consolidates macros used to generate assembly for compatibility across different CPUs or configs. A new header, asm-powerpc/asm-compat.h contains the main compatibility macros. It uses some preprocessor magic to make the macros suitable both for use in .S files, and in inline asm in .c files. Headers (bitops.h, uaccess.h, atomic.h, bug.h) which had their own such compatibility macros are changed to use asm-compat.h. ppc_asm.h is now for use in .S files *only*, and a #error enforces that. As such, we're a lot more careless about namespace pollution here than in asm-compat.h. While we're at it, this patch adds a call to the PPC405_ERR77 macro in futex.h which should have had it already, but didn't. Built and booted on pSeries, Maple and iSeries (ARCH=powerpc). Built for 32-bit powermac (ARCH=powerpc) and Walnut (ARCH=ppc). Signed-off-by: NDavid Gibson <dwg@au1.ibm.com> Signed-off-by: NPaul Mackerras <paulus@samba.org>

Change USER/KERNEL_DS so that the merged version of __strnlen_user can be used which allows us to complete the removal of arch/ppc64/lib/. Signed-off-by: NStephen Rothwell <sfr@canb.auug.org.au>
