* 'v3.7-samsung-fixes-1' of git://git.kernel.org/pub/scm/linux/kernel/git/kgene/linux-samsung:
  ARM: SAMSUNG: Add missing variable declaration in s3c64xx_spi1_set_platdata()
  ARM: S3C24XX: removes unnecessary semicolon
  ARM: S3C24xx: delete double assignment
  ARM: EXYNOS: fix address for EXYNOS4 MDMA1
  ARM: EXYNOS: fixed SYSMMU setup definition to mate parameter name
  + sync to 3.6-rc6

Semihosting enables code running on an ARM target to use
the I/O facilities on a host debugger/emulator through a
simple SVC calls. The host debugger or emulator must have
simple SVC call. The host debugger or emulator must have
semihosting enabled for the special svc call to be trapped
