Mark arches that support A.OUT format by including the following in their
master Kconfig files:
config ARCH_SUPPORTS_AOUT
def_bool y
This should also be set if the arch provides compatibility A.OUT support for
an older arch, for instance x86_64 for i386 or sparc64 for sparc.
I've guessed at which arches don't, based on comments in the code, however I'm
sure that some of the ones I've marked as 'yes' actually should be 'no'.

Fix typo in comments.
BTW: I have to fix coding style in arch/ia64/kernel/time.c also, otherwise
checkpatch.pl will be complaining.

Use task_pgrp_vnr not task_pgrp_nr so we return the process id the processes
pid namespace and not in the initial pid namespace.

Currently we possibly lookup the pid in the wrong pid namespace. So
seq_file convert proc_pid_status which ensures the proper pid namespaces is
passed in.

- Change spin_lock + local_irq_save into spin_lock_irqsave
- Change spin_unlock + local_irq_restore into spin_unlock_irqrestore
- Return ENOTTY if ioctl is not recognized as a cris ioctl.
- Make init functions static.
Changes as suggested by Andrew Morton, plus general cleanup to
ease later consolidation of driver into machine common driver.
- Correct parameter type of gpio_write to const char __user *
- Remove volatile from the arrays of machine dependent registers, use
readl and writel to access them instead.
- Remove useless casts of void.
- Use spin_lock_irqsave for locking.
- Break gpio_write into smaller sub-functions.
- Remove useless breaks after returns.
- Don't perform any change in IO_CFG_WRITE_MODE if values are invalid.
(previously values were set and then set to zero)
- Change cast for copy_to_user to (void __user *)
- Make file_operations gpio_fops static and const.
- Make setget_output static. (However, it's still inline since the CRIS
architecture is still not SMP, which makes the function small enough
to inline)
Clean up issues noticed by Andrew Morton:
- Use a combined struct for allocating the mtd_info and nand_chip structs
instead of using anonymous memory as the example in
Documentation/DocBook/mtdnand.tmpl
- Use kzalloc instead of using kmalloc/memset(0)
- Make crisv32_device_ready static.
- Change parameters of gpio_write (const char * buf -> const char __user *buf)
- Don't initialize static variables to zero.
- Remove useless casts from void.
- Change name of interrupt routine (gpio_pa_interrupt -> gpio_interrupt)
- Use kzmalloc instead of allocating memory and zeroing it manually.
- Correct casts for copy_to_user and copy_from_user to (void __user *)
- Make file_operations gpio_fops static.
- Make ioif_watcher static, not used outside this file.
- Move alignment of init data to page size outside define CONFIG_BLK_DEV_INITRD
This avoids oops due to memory on the same page as init data being freed.
- Change hardcoded page size to use macro from asm/page.h
- Add reserved memory via CONFIG_ETRAX_VMEM_SIZE.
- Use available defines for TEXT_TEXT and INITCALLS.
- Cleanup whitespace.
- Slight tweaks, use $acr + addoq to propagate carry across the loop boundary.
- Better use of latency cycles.
- Remove duplicate folding of carry, it is not needed.
- Change include paths to machine specific headers (asm/arch/hwregs -> hwregs)
- Add cpu_possible_map as cpumask_t and export it.
- Drop struct pt_regs parameter from crisv32_ipi_interrupt.
- timer -> timer0
- do_signal now returns void, and does not have the previous signal set
as a parameter.
- Remove sys_rt_sigsuspend, we can use the common one instead.
- Change sys_sigsuspend to be more like x86, don't call do_signal here.
- handle_signal, setup_frame and setup_rt_frame now return -EFAULT
if we've delivered a segfault, which is used by callers to perform
necessary cleanup.
- Break long lines, correct whitespace and formatting errors.
- Change all spin_lock/local_irq_save to spin_lock_irqsave.
- Change multiple returns in functions where we have a lock to goto out.
- Correct number of arguments to gpio_poll_timer_interrupt, gpio_pa_interrupt.
- Break out gpio_write logic to smaller functions to make it readable.
- In setget_input and setget_output, avoid extra if-indent level.
- Change name LED_* -> CRIS_LED_* to avoid name clash.
- Don't use braces around single statement ifs.
- Fix whitespace errors.
- Remove useless CVS id and log.
- Don't use SANITYCHECK(x) as a macro, test FAST_TIMER_SANITY_CHECKS with
ifdef. This makes it possible for automatic indent etc to work.
- Correct some whitespace errors.
- Don't initialize static variable.
- Include pinmux.h from machine specific directory.
- Add some more symbols: crisv32_pinmux_alloc, crisv32_pinmux_dealloc_fixed,
crisv32_io_get_name and crisv32_io_get
- Moved all calls to register_chrdev to a function called by module_init.
- Added mutex locking.
- Added better error handling at start up.
- Added BIN_TO_BCD of the month value before it is saved to the RTC.
- Corrected the month value returned by pcf8563_readreg.
- Cache the voltage low value at driver init so the battery status
information does not get 'accidentally' cleared when setting the RTC time.
- Removed obsolete CONFIG_ETRAX_RTC_READONLY
- Voltage low ioctl():s RTC_VLOW_RD -> RTC_VL_READ, RTC_VLOW_SET -> RTC_VL_CLR
