modpost: fix module autoloading for OF devices with generic compatible property

2016-05-06T00:38:53Z

Since the wildcard at the end of OF module aliases is gone, autoloading of modules that don't match a device's last (most generic) compatible value fails. For example the CODA960 VPU on i.MX6Q has the SoC specific compatible "fsl,imx6q-vpu" and the generic compatible "cnm,coda960". Since the driver currently only works with knowledge about the SoC specific integration, it doesn't list "cnm,cod960" in the module device table. This results in the device compatible "of:NvpuTCfsl,imx6q-vpuCcnm,coda960" not matching the module alias "of:N*T*Cfsl,imx6q-vpu" anymore, whereas before commit 2f632369ab79 ("modpost: don't add a trailing wildcard for OF module aliases") it matched the module alias "of:N*T*Cfsl,imx6q-vpu*". This patch adds two module aliases for each compatible, one without the wildcard and one with "C*" appended. $ modinfo coda | grep imx6q alias: of:N*T*Cfsl,imx6q-vpuC* alias: of:N*T*Cfsl,imx6q-vpu Fixes: 2f632369ab79 ("modpost: don't add a trailing wildcard for OF module aliases") Link: http://lkml.kernel.org/r/1462203339-15340-1-git-send-email-p.zabel@pengutronix.de Signed-off-by: Philipp Zabel Cc: Javier Martinez Canillas Cc: Brian Norris Cc: Sjoerd Simons Cc: Rusty Russell Cc: Greg Kroah-Hartman Cc: [4.5+] Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

parisc: Use generic extable search and sort routines

2016-03-23T15:00:46Z

Switch to the generic extable search and sort routines which were introduced with commit a272858 from Ard Biesheuvel. This saves quite some memory in the vmlinux binary with the 64bit kernel. Signed-off-by: Helge Deller

ubsan: fix tree-wide -Wmaybe-uninitialized false positives

2016-03-22T22:36:02Z

-fsanitize=* options makes GCC less smart than usual and increase number of 'maybe-uninitialized' false-positives. So this patch does two things: * Add -Wno-maybe-uninitialized to CFLAGS_UBSAN which will disable all such warnings for instrumented files. * Remove CONFIG_UBSAN_SANITIZE_ALL from all[yes|mod]config builds. So the all[yes|mod]config build goes without -fsanitize=* and still with -Wmaybe-uninitialized.

lx-version Report the Linux Version of the current kernel. Add a command to identify the version specified by the banner in the debugged kernel. This lets the user identify the kernel of the running kernel, and will let later scripts compare the banner of the attached kernel against the banner in the vmlinux symbols files to verify that the files are correct.
