[PATCH 02/30] ARM: let armlinux_set_* depend on the correct option

[Sascha Hauer]

We need inline versions of armlinux_set* exactly when
CONFIG_ARM_LINUX is not set, because this is the symbol
used to compile the non inline versions.

[PATCH 15/30] kconfig: fix IS_ENABLED to not require all options to be defined

[Sascha Hauer]

From Linux commit 69349c2dc01c489eccaa4c472542c08e370c6d7e:

    Using IS_ENABLED() within C (vs.  within CPP #if statements) in its
    current form requires us to actually define every possible bool/tristate
    Kconfig option twice (__enabled_* and __enabled_*_MODULE variants).

    This results in a huge autoconf.h file, on the order of 16k lines for a
    x86_64 defconfig.

    Fixing IS_ENABLED to be able to work on the smaller subset of just
    things that we really have defined is step one to fixing this.  Which
    means it has to not choke when fed non-enabled options, such as:

      include/linux/netdevice.h:964:1: warning: "__enabled_CONFIG_FCOE_MODULE" is not defined [-Wundef]

    The original prototype of how to implement a C and preprocessor
    compatible way of doing this came from the Google+ user "comex ." in
    response to Linus' crowdsourcing challenge for a possible improvement on
    his earlier C specific solution:

    	#define config_enabled(x)       (__stringify(x)[0] == '1')

    In this implementation, I've chosen variable names that hopefully make
    how it works more understandable.

-	help
-	  This is a reimplementation of M-Systems DiskOnChip 2000,

-	bool "Allow BBT writes on DiskOnChip Millennium and 2000TSOP"
-	depends on MTD_NAND_DISKONCHIP
-	help
-	  On DiskOnChip devices shipped with the INFTL filesystem (Millennium
-	  and 2000 TSOP/Alon), Linux reserves some space at the end of the
-	  device for the Bad Block Table (BBT).  If you have existing INFTL
-	  data on your device (created by non-Linux tools such as M-Systems'
-	  DOS drivers), your data might overlap the area Linux wants to use for
-	  the BBT.  If this is a concern for you, leave this option disabled and
-	  Linux will not write BBT data into this area.
-	  The downside of leaving this option disabled is that if bad blocks
-	  are detected by Linux, they will not be recorded in the BBT, which
-	  could cause future problems.
-	  Once you enable this option, new filesystems (INFTL or others, created
-	  in Linux or other operating systems) will not use the reserved area.
-	  The only reason not to enable this option is to prevent damage to
-	  preexisting filesystems.
-	  Even if you leave this disabled, you can enable BBT writes at module
-	  load time (assuming you build diskonchip as a module) with the module
-	  parameter "inftl_bbt_write=1".

Re: [PATCH 01/30] USB: Fix typo tranceiver -> transceiver

Forgot to mention that this series is based on a bunch of randconfig
builds. There are some patches missing that I am currently not happy
with, but with them I managed to build dozens of randconfigs without
errors.
