- * 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

- *
- * 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

- * 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.

- * 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).

- * Revision 1.20  2002/10/16 21:16:24  johana
- * Added support for PA high level interrupt.
- * That gives 2ms response time with iodtest for high levels and 2-12 ms
- * response time on low levels if the check is not made in
- * process.c:cpu_idle() as well.
- *
- * Revision 1.19  2002/10/14 18:27:33  johana
- * Implemented alarm handling so select() now works.
- * Latency is around 6-9 ms with a etrax_gpio_wake_up_check() in
- * cpu_idle().
- * Otherwise I get 15-18 ms (same as doing the poll in userspace -
- * but less overhead).
- * TODO? Perhaps we should add the check in IMMEDIATE_BH (or whatever it
- * is in 2.4) as well?
- * TODO? Perhaps call request_irq()/free_irq() only when needed?
- * Increased version to 2.5

- * Mask inverted 8 bit value in setget_input().
- *
- * Revision 1.17  2002/06/17 15:53:01  johana
- * Added IO_READ_INBITS, IO_READ_OUTBITS, IO_SETGET_INPUT and IO_SETGET_OUTPUT
- * that take a pointer as argument and thus can handle 32 bit ports (G)
- * correctly.
- * These should be used instead of IO_READBITS, IO_SETINPUT and IO_SETOUTPUT.
- * (especially if Port G bit 31 is used)
- *
- * Revision 1.16  2002/06/17 09:59:51  johana
- * Returning 32 bit values in the ioctl return value doesn't work if bit
- * 31 is set (could happen for port G), so mask it of with 0x7FFFFFFF.
- * A new set of ioctl's will be added.
- *
- * Revision 1.15  2002/05/06 13:19:13  johana
- * IO_SETINPUT returns mask with bit set = inputs for PA and PB as well.
- *
- * Revision 1.14  2002/04/12 12:01:53  johana
- * Use global r_port_g_data_shadow.
- * Moved gpio_init_port_g() closer to gpio_init() and marked it __init.
- *
- * Revision 1.13  2002/04/10 12:03:55  johana
- * Added support for port G /dev/gpiog (minor 3).
- * Changed indentation on switch cases.
- * Fixed other spaces to tabs.
- *
- * Revision 1.12  2001/11/12 19:42:15  pkj
- * * Corrected return values from gpio_leds_ioctl().
- * * Fixed compiler warnings.
- *
- * Revision 1.11  2001/10/30 14:39:12  johana
- * Added D() around gpio_write printk.
- *
- * Revision 1.10  2001/10/25 10:24:42  johana
- * Added IO_CFG_WRITE_MODE ioctl and write method that can do fast
- * bittoggling in the kernel. (This speeds up programming an FPGA with 450kB
- * from ~60 seconds to 4 seconds).
- * Added save_flags/cli/restore_flags in ioctl.
- *
- * Revision 1.9  2001/05/04 14:16:07  matsfg
- * Corrected spelling error
- *
- * Revision 1.8  2001/04/27 13:55:26  matsfg
- * Moved initioremap.
- * Turns off all LEDS on init.
- * Added support for shutdown and powerbutton.
- *
- * Revision 1.7  2001/04/04 13:30:08  matsfg
- * Added bitset and bitclear for leds. Calls init_ioremap to set up memmapping
- *
- * Revision 1.6  2001/03/26 16:03:06  bjornw
- * Needs linux/config.h
- *

- *
- *  Revision 1.14  2001/02/23 08:36:36  perf
- *  New ABI; syscallnr=r9, arg5=mof, arg6=srp.
- *  Corrected tracesys call check.
- *
- *  Revision 1.13  2001/02/15 08:40:55  perf
- *  H-P by way of perf;
- *  - (_system_call): Don't read system call function address into r1.
- *  - (RBFExit): There is no such thing as a null pop.  Adjust sp by addq.
- *  - (_system_call): Don't use r10 and don't save and restore it.
- *  - (THREAD_ESP0): New constant.
- *  - (_system_call): Inline set_esp0.
- *
- *  Revision 1.12  2001/01/31 17:56:25  orjanf
- *  Added definition of LTASK_PID and made it global.
- *
- *  Revision 1.11  2001/01/10 21:13:29  bjornw
- *  SYMBOL_NAME is defined incorrectly for the compiler options we currently use
- *

- *  * New frame type used when an SBFS frame needs to be popped without
- *    actually restarting the instruction
- *  * Enable interrupts in signal_return (they did so in x86, I hope it's a good
- *    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

- * Revision 1.3  2002/05/28 16:16:07  johana
- * Handle empty fast_timer_list
- *
- * Revision 1.2  2002/05/27 15:38:42  johana
- * Made it compile without warnings on Linux 2.4.
- * (includes, wait_queue, PROC_FS and snprintf)
- *
- * Revision 1.1  2002/05/27 15:32:25  johana
- * arch/etrax100/kernel/fasttimer.c v1.8 from the elinux tree.
- *
- * Revision 1.8  2001/11/27 13:50:40  pkj
- * Disable interrupts while stopping the timer and while modifying the
- * list of active timers in timer1_handler() as it may be interrupted
- * by other interrupts (e.g., the serial interrupt) which may add fast
- * timers.
- *
- * Revision 1.7  2001/11/22 11:50:32  pkj
- * * Only store information about the last 16 timers.
- * * proc_fasttimer_read() now uses an allocated buffer, since it
- *   requires more space than just a page even for only writing the
- *   last 16 timers. The buffer is only allocated on request, so
- *   unless /proc/fasttimer is read, it is never allocated.
- * * Renamed fast_timer_started to fast_timers_started to match
- *   fast_timers_added and fast_timers_expired.
- * * Some clean-up.
- *
- * Revision 1.6  2000/12/13 14:02:08  johana
- * Removed volatile for fast_timer_list
- *
- * Revision 1.5  2000/12/13 13:55:35  johana
- * Added DEBUG_LOG, added som cli() and cleanup
- *
- * Revision 1.4  2000/12/05 13:48:50  johana
- * Added range check when writing proc file, modified timer int handling
- *
- * Revision 1.3  2000/11/23 10:10:20  johana
- * More debug/logging possibilities.
- * Moved GET_JIFFIES_USEC() to timex.h and time.c
- *
- * Revision 1.2  2000/11/01 13:41:04  johana
- * Clean up and bugfixes.
- * Created new do_gettimeofday_fast() that gets a timeval struct
- * with time based on jiffies and *R_TIMER0_DATA, uses a table
- * for fast conversion of timer value to microseconds.
- * (Much faster the standard do_gettimeofday() and we don't really
- * want to use the true time - we want the "uptime" so timers don't screw up
- * when we change the time.
- * TODO: Add efficient support for continuous timers as well.
- *
- * Revision 1.1  2000/10/26 15:49:16  johana
- * Added fasttimer, highresolution timers.

- *  Merge of Linux 2.6.11.
- *
- *  Revision 1.19  2005/01/14 10:07:59  starvik
- *  Fixed warning.
- *
- *  Revision 1.18  2005/01/12 08:10:14  starvik
- *  Re-added the change of frametype when handling kernel page fault fixup
- *  for v10. This is necessary to avoid that the CPU remakes the faulting
- *  access.
- *
- *  Revision 1.17  2005/01/11 13:53:05  starvik
- *  Use raw_printk.
- *
- *  Revision 1.16  2004/12/17 11:39:41  starvik
- *  SMP support.
- *
- *  Revision 1.15  2004/11/23 18:36:18  starvik
- *  Stack is now non-executable.
- *  Signal handler trampolines are placed in a reserved page mapped into all
- *  processes.
- *
- *  Revision 1.14  2004/11/23 07:10:21  starvik
- *  Moved find_fixup_code to generic code.
- *
- *  Revision 1.13  2004/11/23 07:00:54  starvik
- *  Actually use the execute permission bit in the MMU. This makes it possible
- *  to prevent e.g. attacks where executable code is put on the stack.
- *
- *  Revision 1.12  2004/09/29 06:16:04  starvik
- *  Use instruction_pointer
- *
- *  Revision 1.11  2004/05/14 07:58:05  starvik
- *  Merge of changes from 2.4
- *
- *  Revision 1.10  2003/10/27 14:51:24  starvik
- *  Removed debugcode
- *
- *  Revision 1.9  2003/10/27 14:50:42  starvik
- *  Changed do_page_fault signature
- *
- *  Revision 1.8  2003/07/04 13:02:48  tobiasa
- *  Moved code snippet from arch/cris/mm/fault.c that searches for fixup code
- *  to separate function in arch-specific files.
- *
- *  Revision 1.7  2003/01/22 06:48:38  starvik
- *  Fixed warnings issued by GCC 3.2.1
- *
- *  Revision 1.6  2003/01/09 14:42:52  starvik
- *  Merge of Linux 2.5.55
- *
- *  Revision 1.5  2002/12/11 14:44:48  starvik
- *  Extracted v10 (ETRAX 100LX) specific stuff to arch/cris/arch-v10/mm
- *
- *  Revision 1.4  2002/11/13 15:10:28  starvik
- *  pte_offset has been renamed to pte_offset_kernel
- *
- *  Revision 1.3  2002/11/05 06:45:13  starvik
- *  Merge of Linux 2.5.45
- *
- *  Revision 1.2  2001/12/18 13:35:22  bjornw
- *  Applied the 2.4.13->2.4.16 CRIS patch to 2.5.1 (is a copy of 2.4.15).
- *
- *  Revision 1.20  2001/11/22 13:34:06  bjornw
- *  * Bug workaround (LX TR89): force a rerun of the whole of an interrupted
- *    unaligned write, because the second half of the write will be corrupted
- *    otherwise. Affected unaligned writes spanning not-yet mapped pages.
- *  * Optimization: use the wr_rd bit in R_MMU_CAUSE to know whether a miss
- *    was due to a read or a write (before we didn't know this until the next
- *    restart of the interrupted instruction, thus wasting one fault-irq)
- *
- *  Revision 1.19  2001/11/12 19:02:10  pkj
- *  Fixed compiler warnings.
- *
- *  Revision 1.18  2001/07/18 22:14:32  bjornw
- *  Enable interrupts in the bulk of do_page_fault
- *
- *  Revision 1.17  2001/07/18 13:07:23  bjornw
- *  * Detect non-existant PTE's in vmalloc pmd synchronization
- *  * Remove comment about fast-paths for VMALLOC_START etc, because all that
- *    was totally bogus anyway it turned out :)
- *  * Fix detection of vmalloc-area synchronization
- *  * Add some comments
- *
- *  Revision 1.16  2001/06/13 00:06:08  bjornw
- *  current_pgd should be volatile
- *
- *  Revision 1.15  2001/06/13 00:02:23  bjornw
- *  Use a separate variable to store the current pgd to avoid races in schedule
- *
- *  Revision 1.14  2001/05/16 17:41:07  hp
- *  Last comment tweak further tweaked.
- *
- *  Revision 1.13  2001/05/15 00:58:44  hp
- *  Expand a bit on the comment why we compare address >= TASK_SIZE rather
- *  than >= VMALLOC_START.
