2009-12-12kbuild: drop include/asmSam Ravnborg
We no longer use this directory for generated files and all architectures has moved their header files so no symlink tricks are needed either. Drop the symlink and drop the ARCH check. If we really need to check that the SRCARCH has not changed when we build a kernel we can add this check back - but then we will find a more convenient way to store the info.

2009-12-12kbuild: do not check for include/asm-$ARCHSam Ravnborg
No architectures uses include/asm-$ARCH now. So drop check for location of include files Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: Michal Marek <mmarek@suse.cz>
2009-12-12kbuild: drop include2/ used for O=... buildsSam Ravnborg

2009-12-12kbuild: move asm-offsets.h to include/generatedSam Ravnborg
The simplest method was to add an extra asm-offsets.h file in arch/$ARCH/include/asm that references the generated file. We can now migrate the architectures one-by-one to reference the generated file direct - and when done we can delete the temporary arch/$ARCH/include/asm/asm-offsets.h file.

2009-12-12kbuild: search arch/$ARCH/include before include/Sam Ravnborg
The namespace used in arch/$ARCH/include is different from what is used in include/ except for the include/asm directory. This patch gives the arch/$ARCH/include/asm directory priority over include/asm. When we add asm-offsets.h to arch/$ARCH/include/asm/ this patch makes sure we pick up the arch specific version and not the one we have in include/asm. The situation with an asm-offsets.h file located in both include/asm _and_ arch/$ARCH/include/asm will happen when we move more files over to include/generated. This happens because in some cases it is not practical to rename all users so we simply add a file in arch/$ARCH/include/asm that includes the generated version. This is the solution we use for asm-offsets.h as an example. Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Cc: Stephen Rothwell <sfr@canb.auug.org.au> Signed-off-by: Michal Marek <mmarek@suse.cz>
2009-12-12kbuild: fix bzImage build for x86Michael Tokarev
As has been discussed previously (and Sam has been CC'ed), the fix is still incorrect. It replaces "echo -ne" with "/bin/echo -ne", but neither of the two are guaranteed to support the necessary arguments and necessary (hexadecimal) escape sequences. What should be used here is printf(1). The trivial patch below (on top of these kbuild changes) fixes this issue.

moxa_openlock is used for several situations where we want to handle the case of an ioctl that crosses many ports (not just the open tty), and also cases where an open races a deinit (eg a pci unplug) and we hangup a port before we can cope with that.
