Add hwmod structures for I2C controllers on OMAP2420/2430. NOTE: I2C module on OMAP2420 has 16bit registers and causes imprecise aborts if 32bits are read/written to it. Use the HWMOD_16BIT_REG flag to notify the hmwod framework of this hard requirement so that __raw_writew/readw is used to read /write the mdoule registers.

2010-11-07ARM: 6470/1: atomic64: use generic implementation for OABI configurationsWill Deacon
The old apcs-gnu ABI doesn't guarantee that double words are allocated to registers with even alignment, causing the 64-bit exclusive memory operations to be rejected by the assembler. This patch requires that CONFIG_AEABI is set in order to use the native atomic operations and falls back to the generic (spinlock) code otherwise.

2010-11-07ARM: 6468/1: backtrace: fix calculation of thread stack baseWill Deacon
When unwinding stack frames we must take care not to unwind areas of memory that lie outside of the known extent of the stack. This patch fixes an incorrect calculation of the stack base where THREAD_SIZE is added to the stack pointer after it has already been aligned to this value. Since the ALIGN macro performs this addition internally, we end up overshooting the base by 8k.

2010-11-04ARM: 6396/1: Add SWP/SWPB emulation for ARMv7 processorsLeif Lindholm
The SWP instruction was deprecated in the ARMv6 architecture, superseded by the LDREX/STREX family of instructions for load-linked/store-conditional operations. The ARMv7 multiprocessing extensions mandate that SWP/SWPB instructions are treated as undefined from reset, with the ability to enable them through the System Control Register SW bit. This patch adds the alternative solution to emulate the SWP and SWPB instructions using LDREX/STREX sequences, and log statistics to /proc/cpu/swp_emulation. To correctly deal with copy-on-write, it also modifies cpu_v7_set_pte_ext to change the mappings to priviliged RO when user RO.

2010-11-04ARM: 6384/1: Remove the domain switching on ARMv6k/v7 CPUsCatalin Marinas
This patch removes the domain switching functionality via the set_fs and __switch_to functions on cores that have a TLS register. Currently, the ioremap and vmalloc areas share the same level 1 page tables and therefore have the same domain (DOMAIN_KERNEL). When the kernel domain is modified from Client to Manager (via the __set_fs or in the __switch_to function), the XN (eXecute Never) bit is overridden and newer CPUs can speculatively prefetch the ioremap'ed memory. Linux performs the kernel domain switching to allow user-specific functions (copy_to/from_user, get/put_user etc.) to access kernel memory. In order for these functions to work with the kernel domain set to Client, the patch modifies the LDRT/STRT and related instructions to the LDR/STR ones. The user pages access rights are also modified for kernel read-only access rather than read/write so that the copy-on-write mechanism still works. CPU_USE_DOMAINS gets disabled only if the hardware has a TLS register (CPU_32v6K is defined) since writing the TLS value to the high vectors page isn't possible. The user addresses passed to the kernel are checked by the access_ok() function so that they do not point to the kernel space.

Recent changes in s3c gpio break mini2440 board and may be others. The problem is that mach-mini2440.c: mini2440_init() (where we call s3c_gpio_setpull()) is called before s3c2440.c: s3c2440_init() (where we initialize s3c24xx_gpiocfg_default.set_pull function pointer). This causes dereferencing of NULL pointer at boot time and a kernel panic.
