warn about use of uninstalled kernel headers

2009-10-11T21:21:25+00:00

User applications frequently hit problems when they try to use the kernel headers directly, rather than the exported headers. This adds an explicit warning for this case, and points to a URL holding an explanation of why this is wrong and what to do about it. Signed-off-by: Arnd Bergmann Signed-off-by: Sam Ravnborg

kbuild: mkcompile_h: trivial cleanups

UTS_TRUNCATTE is simpler this way, and now editors idetify this as a shell script. Signed-off-by: Felipe Contreras Acked-by: WANG Cong Signed-off-by: Sam Ravnborg

kbuild: Fix size_append issue for bzip2/lzma kernel

2009-10-11T21:21:25+00:00

The Makefile.lib will call "echo -ne" to append uncompressed kernel size to bzip2/lzma kernel image. The "echo" here depends on the shell that /bin/sh pointing to. On Ubuntu system, the /bin/sh is pointing to dash, which does not support "echo -e" at all. Use /bin/echo instead of shell echo should always be safe.

kbuild,scripts: use non-builtin echo for '-e'

2009-10-11T21:21:25+00:00

Alek reported that on Ubuntu, where dash is used, 'echo -e' can't work, so let's use non-builtin echo in this case. Reported-by: Alek Du Signed-off-by: WANG Cong Signed-off-by: Sam Ravnborg

kbuild: fix the binrpm-pkg target to work with KBUILD_OUTPUT set

2009-10-11T21:21:24+00:00

The binrpm-pkg target (binary RPM only) fails when called with KBUILD_OUTPUT set. This patch makes it work. For the rpm-pkg target (source + binary RPM), building with KBUILD_OUTPUT set is not possible and also not needed as the actual build is done in a temporary directory anyway, so check that KBUILD_OUTPUT is not set in that case to avoid later errors.

spi: prefix modalias with "spi:"

2009-09-23T14:39:43+00:00

This makes it consistent with other buses (platform, i2c, vio, ...). I'm not sure why we use the prefixes, but there must be a reason. This was easy enough to do it, and I did it.

spi: add support for device table matching

2009-09-23T14:39:43+00:00

With this patch spi drivers can use standard spi_driver.id_table and MODULE_DEVICE_TABLE() mechanisms to bind against the devices. Just like we do with I2C drivers. This is useful when a single driver supports several variants of devices but it is not possible to detect them in run-time (like non-JEDEC chips probing in drivers/mtd/devices/m25p80.c), and when platform_data usage is overkill. This patch also makes life a lot easier on OpenFirmware platforms, since with OF we extensively use proper device IDs in modaliases.

kallsyms: fix segfault in prefix_underscores_count()

2009-09-23T14:39:30+00:00

Commit b478b782e110fdb4135caa3062b6d687e989d994 "kallsyms, tracing: output more proper symbol name" introduces a "bugfix" that introduces a segfault in kallsyms in my configurations. The cause is the introduction of prefix_underscores_count() which attempts to count underscores, even in symbols that do not have them. As a result, it just uselessly runs past the end of the buffer until it crashes: CC init/version.o LD init/built-in.o LD .tmp_vmlinux1 KSYM .tmp_kallsyms1.S /bin/sh: line 1: 16934 Done sh-linux-gnu-nm -n .tmp_vmlinux1 16935 Segmentation fault | scripts/kallsyms > .tmp_kallsyms1.S make: *** [.tmp_kallsyms1.S] Error 139 This simplifies the logic and just does a straightforward count.
