* sh: pci: Allow register_pci_controller() to handle overlapping regions.Paul Mundt2009-06-161-12/+2
| | | | | | | | Some host controllers (such as SH7786) have overlapping regions that are fixed in hardware. The resource allocator does the right thing in managing this space already, so the conflict case is non-fatal. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

* sh: Make the atomic functions safe for irqsoff tracingMatt Fleming2009-06-151-12/+12
| | | | | | | | | | | | | | | The irqsoff tracer uses the atomic_* functions internally, but the implementations of those functions in arch/sh/include/asm/atomic-irq.h disable irqs to achieve atomicity. A continuous loop ensues where we disable interrupts, trace the interrupt disabling, call atomic_* functions, disable interrupts, trace the interrupt disabling, etc.. The simplest solution to all this is to just convert uses of local_irq_save()/local_irq_restore() the raw_* equivalents because the raw_* equivalents don't call trace_hardirqs_on()/trace_hardirqs_off().

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The unaligned address exception handler (and others) does not scan the fixup tables before oopsing. This is bad because it means passing a badly aligned pointer from user space might crash the kernel. Fix this by scanning the fixup tables in _exception(). This should resolve the issue for unaligned addresses as well as other less common exceptions that might be happening during a userspace access. The page fault handler already does fixup processing.

The solution is the pass a list of I2C devices in the platform data to the Open Cores driver. This is useful for MFD drivers.

Recently during migration to 2008R1.5-RC3 we losted access to the RTC. The RTC driver calls 'i2c_transfer()' which in turns calls 'bfin_twi_master_xfer()' in i2c-bfin-twi.c. Compared with 2007R1, it looks like the 2008R1.5 version of i2c-bin-twi.c has a new mode 'TWI_I2C-MODE_REPEAT' which corresponds to the Repeat Start Condition described in the HRM. However, according to the HRM, at XMIT or RECV interrupt and when the data count is 0, not only is the RESTART bit supposed to be set, but MDIR must also be set if the next operation is a receive sequence, and cleared if not. Currently there is no code that looks at the I2C_M_RD bit in the flag from the next cur_msg and set/clear the MDIR flag accordingly at the same time that the RSTART bit is set. Instead, MDIR is set or cleared (by OR'ing with 0?) after the RESTART bit has been cleared during handling of MCOMP interrupt. It appears that this is causing our failure with reading the RTC, as a quick patch to set/clear MDIR when RESTART is set seem to solve our problem.

The "mce=no_cmci" boot option disables the CMCI feature. Since CMCI is a new feature so having boot controls to disable it will be a help if the hardware is misbehaving. The "mce=dont_log_ce" boot option disables logging for corrected errors. All reported corrected errors will be cleared silently. This option will be useful if you never care about corrected errors. The "mce=ignore_ce" boot option disables features for corrected errors, i.e. polling timer and cmci. All corrected events are not cleared and kept in bank MSRs. Usually this disablement is not recommended, however it will be a help if there are some conflict with the BIOS or hardware monitoring applications etc., that clears corrected events in banks instead of OS. [ And trivial cleanup (space -> tab) for doc is included. ] Signed-off-by: Hidetoshi Seto <seto.hidetoshi@jp.fujitsu.com> Reviewed-by: Andi Kleen <ak@linux.intel.com> LKML-Reference: <4A30ACDF.5030408@jp.fujitsu.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
