[PATCH] uml: uml-makefile-nicer uses SYMLINK incorrectly

2006-05-02T01:17:45Z

Blaisorblade's uml-makefile-nicer makes a V=0 build say SYMLINK where what's happening is really a LINK. Signed-off-by: Jeff Dike Acked-by: Paolo 'Blaisorblade' Giarrusso Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[PATCH] uml: fix compilation and execution with hardened GCC

2006-05-02T01:17:45Z

To make some half-assembly stubs compile, disable various "hardened" GCC features: *) we can't make it build PIC code as we need %ebx to do syscalls and GCC wants it free for PIC *) we can't leave stack protection as the stub is moved (not relocated!) in memory so the RIP-relative access to the canary tries reading from an unmapped address and causes a segfault, since we move the stub of various megabytes (the exact amount will be decided at runtime) away from the link-time address.

[PATCH] uml: use Kbuild tracking for all files and fix compilation output

2006-05-02T01:17:45Z

Move the build of user-offsets to arch/um/sys-$(SUBARCH), where it's located. So we can also build it via Kbuild with its dependency tracking rather than by hand. While hacking here, fix also a lot of little cosmetic things. Signed-off-by: Paolo 'Blaisorblade' Giarrusso Acked-by: Jeff Dike Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[PATCH] uml: fix parallel make early failure on clean tree

2006-04-11T13:18:37Z

Parallel make failed once for me - fix this by adding the appropriate command (mkdir before creating a link in that dir). Signed-off-by: Paolo 'Blaisorblade' Giarrusso Acked-by: Sam Ravnborg Cc: Jeff Dike Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[PATCH] uml: split ldt.h in arch-independent and arch-dependant code

2006-03-31T20:18:51Z

ldt-{i386,x86_64}.h is made of two different parts - some code for parsing of LDT descriptors, which is arch-dependant, and the code to handle uml_ldt_t (an LDT block inside UML), which is mostly arch-independant (among x86 and x86_64, at least). Join the common part in a single file (ldt.h) and split the rest away (host_ldt-{i386,x86_64}.h). This is needed because processor.h, with next patches, will start including the LDT descriptor parsing macros in host_ldt.h, but it can't include ldt.h because it uses semaphores (and to define semaphores one must first include processor.h!).

kbuild: change kbuild to not rely on incorrect GNU make behavior

2006-03-05T23:09:51Z

The kbuild system takes advantage of an incorrect behavior in GNU make. Once this behavior is fixed, all files in the kernel rebuild every time, even if nothing has changed. This patch ensures kbuild works with both the incorrect and correct behaviors of GNU make. For more details on the incorrect behavior, see: http://lists.gnu.org/archive/html/bug-make/2006-03/msg00003.html Changes in this patch: - Keep all targets that are to be marked .PHONY in a variable, PHONY. - Add .PHONY: $(PHONY) to mark them properly. - Remove any $(PHONY) files from the $? list when determining whether targets are up-to-date or not.

[PATCH] uml: comments about libc-conflict guards

2006-02-01T16:53:22Z

While fixing myself the mktime conflict (which someone already merged), I also improved a few comments. Merge them up. Signed-off-by: Paolo 'Blaisorblade' Giarrusso Cc: Jeff Dike Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[PATCH] uml: add a build dependency

2006-02-01T16:53:22Z

kern_constants.h now depends on arch/um/include to make sure it exists before we try to create symlinks in it. Signed-off-by: Jeff Dike Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds
