[PATCH] uml: fix compilation options for USER_OBJS

2006-10-30T20:08:41+00:00

From: Jeff Dike , Paolo Giarrusso 

Make sure that when compiling USER_OBJS the correct compilation options are
passed; since they are compiled with USER_CFLAGS which is derived from
CFLAGS, make sure it is a recursively evaluated variable, so that changes
to CFLAGS done afterwards the inclusion of arch/$(ARCH)/Makefile are
reflected in USER_CFLAGS.

For instance, without this patch userspace objects are never compiled with
debug info active.

Attack of "the the"s in arch

2006-10-03T20:21:02+00:00

The patch below corrects multiple occurances of "the the"
typos across several files, both in source comments and KConfig files.
There is no actual code changed, only text.  Note this only affects the /arch
directory, and I believe I could find many more elsewhere. :)

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

2006-05-02T01:17:45+00:00

Blaisorblade's uml-makefile-nicer makes a V=0 build say SYMLINK where
what's happening is really a LINK.

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

2006-05-02T01:17:45+00:00

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

2006-05-02T01:17:45+00:00

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.

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

2006-04-11T13:18:37+00:00

Parallel make failed once for me - fix this by adding the appropriate command
(mkdir before creating a link in that dir).

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

2006-03-31T20:18:51+00:00

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

2006-03-05T23:09:51+00:00

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.
