Merge branch 'cris' of git://www.jni.nu/cris

* 'cris' of git://www.jni.nu/cris: (158 commits)
  CRIS v32: Remove hwregs/timer_defs.h, it is now architecture specific.
  CRIS v32: Change drivers/i2c.c locking.
  CRIS v32: Rewrite ARTPEC-3 gpio driver to avoid volatiles and general cleanup.
  CRIS: Add new timerfd syscall entries.
  MAINTAINERS: Add my information for the CRIS port.
  CRIS v32: Correct spelling of bandwidth in function name.
  CRIS v32: Clean up nandflash.c for ARTPEC-3 and ETRAX FS.
  CRIS v10: Cleanup of drivers/gpio.c
  CRIS v10: drivers/net/cris/eth_v10.c rename LED defines to CRIS_LED to avoid name clash.
  CRIS: Make io_pwm_set_period members unsigned in etraxgpio.h
  CRIS: Move ETRAX_AXISFLASHMAP to common Kconfig file.
  CRIS: Drop regs parameter from call to profile_tick in kernel/time.c
  CRIS v32: Fix minor formatting issue in mach-a3/io.c
  CRIS v32: Initialize GIO even if we're rambooting in kernel/head.S
  CRIS v32: Remove kernel/arbiter.c, it now exists in machine dependent directory.
  CRIS v32: Minor changes to avoid errors in asm-cris/arch-v32/hwregs/reg_rdwr.h
  CRIS v32: arch-v32/hwregs/intr_vect_defs.h moved to machine dependent directory.
  CRIS v32: Correct offset for TASK_pid in asm-cris/arch-v32/offset.h
  CRIS v32: Move register map header to machine dependent directory.
  CRIS v32: Let compiler know that memory is clobbered after a break op.

- * The first partition ends at the start of the partition table.
- *
- * Revision 1.27  2002/08/21 09:23:13  jonashg
- * Speling.
- *
- * Revision 1.26  2002/08/21 08:35:20  jonashg
- * Cosmetic change to printouts.
- *
- * Revision 1.25  2002/08/21 08:15:42  jonashg
- * Made it compile even without CONFIG_MTD_CONCAT defined.
- *
- * Revision 1.24  2002/08/20 13:12:35  jonashg
- * * New approach to probing. Probe cse0 and cse1 separately and (mtd)concat
- *   the results.
- * * Removed compile time tests concerning how the mtdram driver has been
- *   configured. The user will know about the misconfiguration at runtime
- *   instead. (The old approach made it impossible to use mtdram for anything
- *   else than RAM boot).
- *
- * Revision 1.23  2002/05/13 12:12:28  johana
- * Allow compile without CONFIG_MTD_MTDRAM but warn at compiletime and
- * be informative at runtime.
- *
- * Revision 1.22  2002/05/13 10:24:44  johana
- * Added #if checks on MTDRAM CONFIG
- *
- * Revision 1.21  2002/05/06 16:05:20  johana
- * Removed debug printout.
- *
- * Revision 1.20  2002/05/06 16:03:00  johana
- * No more cramfs as root hack in generic code.
- * It's handled by axisflashmap using mtdram.
- *
- * Revision 1.19  2002/03/15 17:10:28  bjornw
- * Changed comment about cached access since we changed this before
- *
- * Revision 1.18  2002/03/05 17:06:15  jonashg
- * Try amd_flash probe before cfi_probe since amd_flash driver can handle two
- * (or more) flash chips of different model and the cfi driver cannot.
- *
- * Revision 1.17  2001/11/12 19:42:38  pkj
- * Fixed compiler warnings.
- *
- * Revision 1.16  2001/11/08 11:18:58  jonashg
- * Always read from uncached address to avoid problems with flushing
- * cachelines after write and MTD-erase. No performance loss have been
- * seen yet.
- *
- * Revision 1.15  2001/10/19 12:41:04  jonashg
- * Name of probe has changed in MTD.
- *
- * Revision 1.14  2001/09/21 07:14:10  jonashg
- * Made root filesystem (cramfs) use mtdblock driver when booting from flash.
- *
- * Revision 1.13  2001/08/15 13:57:35  jonashg
- * Entire MTD updated to the linux 2.4.7 version.
- *
- * Revision 1.12  2001/06/11 09:50:30  jonashg
- * Oops, 2MB is 0x200000 bytes.
- *
- * Revision 1.11  2001/06/08 11:39:44  jonashg
- * Changed sizes and offsets in axis_default_partitions to use
- * CONFIG_ETRAX_PTABLE_SECTOR.
- *
- * Revision 1.10  2001/05/29 09:42:03  jonashg
- * Use macro for end marker length instead of sizeof.
- *
- * Revision 1.9  2001/05/29 08:52:52  jonashg
- * Gave names to the magic fours (size of the ptable end marker).
- *
- * Revision 1.8  2001/05/28 15:36:20  jonashg
- * * Removed old comment about ptable location in flash (it's a CONFIG_ option).
- * * Variable ptable was initialized twice to the same value.
- *
- * Revision 1.7  2001/04/05 13:41:46  markusl
- * Updated according to review remarks
- *
- * Revision 1.6  2001/03/07 09:21:21  bjornw
- * No need to waste .data
- *
- * Revision 1.5  2001/03/06 16:27:01  jonashg
- * Probe the entire flash area for flash devices.
- *
- * Revision 1.4  2001/02/23 12:47:15  bjornw
- * Uncached flash in LOW_MAP moved from 0xe to 0x8
- *
- * Revision 1.3  2001/02/16 12:11:45  jonashg
- * MTD driver amd_flash is now included in MTD CVS repository.
- * (It's now in drivers/mtd).
- *
- * Revision 1.2  2001/02/09 11:12:22  jonashg
- * Support for AMD compatible non-CFI flash chips.
- * Only tested with Toshiba TC58FVT160 so far.
- *
- * Revision 1.1  2001/01/12 17:01:18  bjornw
- * * Added axisflashmap.c, a physical mapping for MTD that reads and understands
- *   Axis partition-table format.
- *
- *

- *  - (THREAD_ESP0): New constant.
- *  - (_system_call): Inline set_esp0.

- *    idea)
- *
- *  Revision 1.8  2000/11/17 16:53:35  bjornw
- *  Added detection of frame-type in Rexit, so that mmu_bus_fault can
- *  use ret_from_intr in the return-path to check for signals (like SEGV)
- *  and other foul things that might have occurred during the fault.
- *
- *  Revision 1.7  2000/10/06 15:04:28  bjornw
- *  Include mof in register savings
- *
- *  Revision 1.6  2000/09/12 16:02:44  bjornw
- *  Linux-2.4.0-test7 derived updates
- *
- *  Revision 1.5  2000/08/17 15:35:15  bjornw

- * * end destination is __vmlinux_end in RAM.
- * * _romfs_start moved because of virtual memory.
- *
- * Revision 1.7  2000/11/21 13:55:29  bjornw
- * Use CONFIG_CRIS_LOW_MAP for the low VM map instead of explicit CPU type
- *
- * Revision 1.6  2000/10/06 12:36:55  bjornw
- * Forgot swapper_pg_dir when changing memory map..
- *
- * Revision 1.5  2000/10/04 16:49:30  bjornw
- * * Fixed memory mapping in LX
- * * Check for cramfs instead of romfs
