Re: linux-next: Tree for July 7 (kconfig regression)

[Arnaud Lacombe]

Hi folks,

I introduced a regression in the -kbuild tree in way autoconf.h was
generated. In more details, if the Kconfig did not specify the "0x"
prefix of an hexadecimal default value, this prefix ended up missing
too in autoconf.h, thus breaking the build or generating incorrect
value. Repartition of the faulty symbols is the following:

 arch/arm/Kconfig                   |    2
 arch/blackfin/Kconfig              |    3
 arch/cris/arch-v10/Kconfig         |   17
 arch/cris/arch-v10/drivers/Kconfig |   5
 arch/cris/arch-v32/Kconfig         |   19
 arch/cris/arch-v32/mach-a3/Kconfig |   14
 arch/cris/arch-v32/mach-fs/Kconfig |   22
 arch/m32r/Kconfig                  |   18
 arch/m68k/Kconfig.nommu            |    4
 arch/x86/Kconfig                   |    1
 drivers/media/radio/Kconfig        |   8
 drivers/mtd/devices/Kconfig        |    2
 drivers/mtd/maps/Kconfig           |    1
 drivers/mtd/nand/Kconfig           |    1
 sound/oss/Kconfig                  |   19

A patch, addressing the regression, is available at:

https://patchwork.kernel.org/patch/975652/

It should be part of the -kbuild tree for the next -next iteration.

Sorry for the disturbance,
 - Arnaud
