Introduce fixed sys_sync_file_range2() syscall, implement on PowerPC and ARM

2007-06-28T18:38:30+00:00

Not all the world is an i386.  Many architectures need 64-bit arguments to be
aligned in suitable pairs of registers, and the original
sys_sync_file_range(int, loff_t, loff_t, int) was therefore wasting an
argument register for padding after the first integer.  Since we don't
normally have more than 6 arguments for system calls, that left no room for
the final argument on some architectures.

Fix this by introducing sys_sync_file_range2(int, int, loff_t, loff_t) which
all fits nicely.  In fact, ARM already had that, but called it
sys_arm_sync_file_range.  Move it to fs/sync.c and rename it, then implement
the needed compatibility routine.  And stop the missing syscall check from
bitching about the absence of sys_sync_file_range() if we've implemented
sys_sync_file_range2() instead.

Tested on PPC32 and with 32-bit and 64-bit userspace on PPC64.

[ARM] Update show_regs/oops register format

2007-06-18T14:04:42+00:00

Add the kernel release and version information to the output of
show_regs/oops.  Add the CPU PSR register.  Avoid using printk
to output partial lines; always output a complete line.

Re-combine the "Control" and "Table + DAC" lines after nommu
separated them; we don't want to waste vertical screen space
needlessly.

[ARM] 4444/2: OSIRIS: CPLD suspend fix

2007-06-11T08:09:31+00:00

Ensure the CPLD 8bit settings are preserved over a suspend/resume
cycle as the CPU sends a hard-reset at resume time.

[ARM] VFP: fix section mismatch error

2007-06-10T11:22:20+00:00

Fix a real section mismatch issue; the test code is thrown away after
initialisation, but if we do not detect the VFP hardware, it is left
hooked into the exception handler.  Any VFP instructions which are
subsequently executed risk calling the discarded exception handler.

Introduce a new "null" handler which returns to the "unrecognised
fault" return address.

[ARM] 4421/1: AT91: Value of _KEY fields.

2007-06-03T16:52:35+00:00

Use the actual value (0xA5) for the AT91_SHDW_KEY and AT91_WDT_KEY
register fields instead of a bitmask.

This is consistent with how AT91_RSTC_KEY is defined, and is easier to
use in code.

[ARM] 4422/1: Fix default value handling in gpio_direction_output (PXA)

2007-06-02T20:31:48+00:00

The default value passed through to pxa_gpio_mode() is lost
due to a missing GPIO_DFLT_HIGH mask for nonzero values.  The enclosed
patch fixes this programming error.

[ARM] 4412/1: S3C2412: reset errata fix

2007-05-30T12:15:23+00:00

The S3C2412 has an reset-errata where the clock
may cause a glitch switching back to EXTCLK. We
force a switch to EXTCLK before writing the
reset register to force use of the CLKCON sync
logic to properly switch.

Fix problem reported by Matthieu Castet.
