Merge branch 'randconfig-fixes' into next/fixes-non-critical

This is the first batch of a much longer series of bug fixes
found during randconfig testing. This part are all the simple
patches that are applicable for the arm-soc tree, while most
other fixes will likely go through other maintainers.

* randconfig-fixes: (50 commits)
  ARM: tegra: make debug_ll code build for ARMv6
  ARM: sunxi: fix build for THUMB2_KERNEL
  ARM: exynos: add missing include of linux/module.h
  ARM: exynos: fix l2x0 saved regs handling
  ARM: samsung: select CRC32 for SAMSUNG_PM_CHECK
  ARM: samsung: select ATAGS where necessary
  ARM: samsung: fix SAMSUNG_PM_DEBUG Kconfig logic
  ARM: samsung: allow serial driver to be disabled
  ARM: s5pv210: enable IDE support in MACH_TORBRECK
  ARM: s5p64x0: fix building with only one soc type
  ARM: s3c64xx: select power domains only when used
  ARM: s3c64xx: MACH_SMDK6400 needs HSMMC1
  ARM: s3c24xx: osiris dvs needs tps65010
  ARM: s3c24xx: fix gta02 build error
  ARM: s3c24xx: MINI2440 needs I2C for EEPROM_AT24
  ARM: integrator: only select pl01x if TTY is enabled
  ARM: realview: fix sparsemem build
  ARM: footbridge: make screen_info setup conditional
  ARM: footbridge: fix build with PCI disabled
  ARM: footbridge: don't build floppy code for addin mode
