This patch changes a few functions into returning void. The return values were not used anyway, so I think it should not be a problem. Also removed a little leftover bit from TT mode. Signed-off-by:

This patch removes a variable which was not used in two functions. Yet another code cleanup, nothing really significant. Please note that I could not test this on x86_64. I don't have the hardware for it. [ jdike - Bits of tidying around the affected code. Also, it's fine on x86_64 ] Signed-off-by:

The previous const-ing patch consted a string which shouldn't have been, and I didn't notice the gcc warning. ubd_setup can't take a const char * because its address is assigned to something which expects a char *arg. Many setups modify the string they are given, they can't be const. Signed-off-by:

The earlier pgtable.h tidying patch made things a bit too tidy. Add back a header which is needed in VMALLOC_START and friend. Also add back a definition of pmd_page_vaddr, which is needed on x86_64. Signed-off-by:

Large pieces of include/asm/pgtable.h were unused cruft. This uncovered arch/um/kernel/trap.c needing skas.h in order to get ptrace_faultinfo. Signed-off-by:

Tidy kern_util.h. It turns out that most of the function declarations aren't used, so they can go away. os.h no longer includes kern_util.h, so files which got it through os.h now need to include it directly. A number of other files never needed it, so these includes are deleted. The structure which was used to pass signal handlers from the kernel side to the userspace side is gone. Instead, the handlers are declared here, and used directly from libc code. This allows arch/um/os-Linux/trap.c to be deleted, with its remnants being moved to arch/um/os-Linux/skas/trap.c. arch/um/os-Linux/tty.c had its inclusions changed, and it needed some style attention, so it got tidied.

Suggested by Geert Uytterhoeven - use const.h to get constants that are usable in both C and assembly. I can't include it directly since this code can't include kernel headers. const.h is also for numeric constants that can be typed by tacking a "UL" or similar on the end. The constants here have to be typed by casting them. So, the relevant parts of const.h are copied here and modified in order to allow the constants to be uncasted in assembly and casted in C.

This patch also does some improvements for uml code. Improvements include dropping unnecessary cast, killing some unnecessary code and still some constifying for pointers etc.. Signed-off-by:

bugs.c, for both i386 and x86_64, can undergo further cleaning - The i386 arch_check_bugs only does one thing, so we might as well inline the cmov checking. The i386 includes can be trimmed down a bit. arch_init_thread wasn't used, so it is deleted. The panics in arch_handle_signal are turned into printks because the process is about to get segfaulted anyway, so something is dying no matter what happens here. Also, the return value was always the same, so it contained no information, so it can be void instead. The name is changed to arch_examine_signal because it doesn't handle anything. The caller of arch_handle_signal, relay_signal, does things in a different order. The kernel-mode signal check is now first, which puts everything else together, making things a bit clearer conceptually. [akpm@linux-foundation.org: coding-style fixes] Signed-off-by:

This patch introduces a new way of checking for the cmov instruction. I use signal handling instead of reading /proc/cpuinfo.

Implement get_wchan - the algorithm is similar to x86. It starts with the stack pointer of the process in question and looks above that for addresses that are kernel text. The second one which isn't in the scheduler is the one that's returned. The first one is ignored because that will be UML's own context switching routine. Signed-off-by:

init.h started breaking now for some reason. It turns out that there wasn't a definition of __used. Fixed this by copying the relevant stuff from compiler.h in the userspace case, and including compiler.h in the kernel case. [xiyou.wangcong@gmail.com: added definition of __section] Signed-off-by:

An extra error handling label is needed for the case where the ioremap has succeeded. The problem was detected using the following semantic match (http://www.emn.fr/x-info/coccinelle/) // <smpl> @@ type T,T1,T2; identifier E; statement S; expression x1,x2; constant C; int ret; @@ T E; ... * E = ioremap(...); if (E == NULL) S ... when != iounmap(E) when != if (E != NULL) { ... iounmap(E); ...} when != x1 = (T1)E if (...) { ... when != iounmap(E) when != if (E != NULL) { ... iounmap(E); ...} when != x2 = (T2)E ( * return; | * return C; | * return ret; ) } // </smpl> Signed-off-by:

Improve including of architecture dependent Kconfig files. - Always include the architecture dependent Kconfig files. - Wrap architecture dependent Kconfig files inside an appropriate "if ETRAX_ARCH_Vxx" block. This makes it possible to run the configuration even without the arch links, which are created later in the build process. Signed-off-by:
