dasd driver changes: - Fix debug feature usage. The sprinf event/exception functions write a pointer to a format string (%s) to the log. These strings must be valid at the time the DBF-log is read. - Some coding style reformatting. Signed-off-by:

It seems that linker script for userspace software are quite toolchain-depending, at least because what we use is a merge between builtin LD scripts (see strings /usr/bin/ld) and normal kernel linking scripts. Plus, a number of people are having toolchain-related troubles building UML (even assertion failures on linking, with Gentoo and Fedora 2). So, let's try to make UML nicer for binutils.

From: Bodo Stroesser <bstroesser@fujitsu-siemens.com> Add stack addresses to print of symbols from stack trace. For stack analysis it's important to have this information. Signed-off-by:
Bodo Stroesser <bstroesser@fujitsu-siemens.com> For UML, we should also copy the CONFIG_FRAME_POINTER stack walking from i386, and move the result to sys-i386. Another note: this should be done for i386 also, if ksymoops does not have problems. Signed-off-by:

* Fix the use of errno: it refers to the __errno_location glibc definition when in ubd_user.c, and hence works; but in ubd_kern.c it refers to kernel_errno, which is different. So use the return value of os_* functions, as we should always have done. * Remove {read,write}_ubd_fs(), which are just silly. Signed-off-by: -
Paolo \'Blaisorblade\' Giarrusso authored
Most code of ubd_user.c already uses the os_* functions, so it can be moved to ubd_kern.c. This patch simply moves the code without any hidden changes. The only change is inside io_thread(): since it calls signal(), I created a little function in ubd_user.c which just calls signal() with the right parameters. In a later patch (send together) I'll do some changes, to fix the usage of errno (which makes this code break when moved in a kernelspace file) and for some other little cleanups. Signed-off-by:

When parsing the <flags> section in ubd<n><flags>=file[,file2], instead of requiring that the flags are specified in a certain order, just make the code smarter. Signed-off-by:
-
Paolo \'Blaisorblade\' Giarrusso authored
Currently we can use this syntax ubd<n>[<flags>]=file1,file2. However, writing things as ubd0=~/Uml/file1,~/Uml/file2 does not work; in fact, the shell won't expand the second '~', since it's not at a path beginning; possibly even other shell expansions don't work here. So simply allow using, instead of the ',' separator, the ':' separator. The ',' separator can still be used to preserve backward compatibility. Signed-off-by:

UML has his own initcall mechanism to handle his special userspace initialization (they are called in different moments, so they are indeed It must also duplicate some definition for the benefit of userspace code - but those definition weren't in sync with the main code. Also, the UML own macros missed __attribute_used__. Both problems are fixed by this patch. Signed-off-by:

Cleanup: simplify a lot of strange constructs and whatever present in arch/um/Makefile. Also, get rid of redundant cleaning code introduced in "uml-fix-make-clean.patch" from 2.6.10-mm3 - when it was written it made sense, but I fixed most problems it addressed in a more elegant way. Also about that, don't remove $(ARCH_SYMLINKS) in make clean, but rather in make mrproper as we already do, like for include/asm-um and other symlinks. Finally, remove one wrong thing (almost a bug) introduced in that - the usage of the clean-dirs construct: clean-dirs := sys-$(SUBARCH) which is intended to delete one whole folder, rather than to descend to clean it, when used in normal Makefiles (not in the arch Makefile where is used, with no effect). It's also not needed because that folder is cleaned because is listed in either $(core-y) or $(libs-y). Signed-off-by:

Finally, we end with this the need to update arch/um/Kconfig_block with changes in drivers/block/Kconfig - we include directly that; UML-specific entries were moved into it (they are very few). Signed-off-by:

If UML wants to open an xterm channel and the xterm does not run properly (eg. terminates soon after starting) we will get a hang (a comment added in the patch explains why). This avoids the most common cause for this and adds a comment (which long term will go away with a rewrite of that code); the complete fix would be to catch the xterm process dying, up(&data->sem), and -EIO all requests from that point onwards. That applies for some of the other channels too, so part of the code should probably be abstracted a little and generalized. Signed-off-by:

This patch is intended to fix a bug in timer_suspend() on x86_64 that causes hard lockups on suspend with swsusp and provide some optimizations. It is based on the Nigel Cunningham's patches to to reduce delay in arch/kernel/time.c. Signed-off-by:

Optimize first/node_node Optimize nodemask_t slightly. The x86-64 find_first/next_bit uses __builtin_constant_p on the size argument to special cases small single long word searches. But most gccs don't make __builtin_constant_p true when an argument is passed through an inline function. Move the constant into the inline function to avoid this. This generates a lot better code for node searches on x86-64. Signed-off-by:
