Use raw_smp_processor_id() instead of get_cpu() as we don't need the extra features of get_cpu(). Signed-off-by:

The udelay() inline for ia64 uses the ITC. If CONFIG_PREEMPT is enabled and the platform has unsynchronized ITCs and the calling task migrates to another CPU while doing the udelay loop, then the effective delay may be too short or very, very long. This patch disables preemption around 100 usec chunks of the overall desired udelay time. This minimizes preemption-holdoffs. udelay() is now too big to be inline, move it out of line and export it.

We have found some issues with Au1550 AC'97 OSS driver in 2.6 (sound/oss/au1550_ac97.c), though it also should concern 2.4 driver (drivers/sound/au1550_psc.c). start_dac() grabs a spinlock already held by its caller, au1550_write(). This doesn't show up with the standard UP spinlock impelmentation but when the different one (mutex based) is in use, a lockup happens. And the interrupt handlers also didn't grab the spinlock -- that's OK in the usual kernel but not when the IRQ handlers are threaded. So, they're grabbing the spinlock now (as every correct interrupt handler should do). Signed-off-by:

While doing some testing I discovered that if the BIOS on a board does not properly setup the DMI information it leads to a panic in the IPMI code. The panic is due to dereferencing a pointer which is not initialized. The pointer is initialized in port_setup() and/or mem_setup() and used in init_one_smi() and cleanup_one_si(), however if either port_setup() or mem_setup() return ENODEV the pointer does not get initialized.

The following patch fixes a bug where if the journal is aborted, it can leave a transaction open. The result will be a BUG when another code path attempts to start a transaction and will get a "nesting into different fs" error, since current->journal_info will be left non-NULL.

This should have been part of the original io error patch, but got dropped somewhere along the way. It's extremely important when handling the i/o error in the journal to not commit the transaction with corrupt data. This patch adds that code back in. Signed-off-by:

Also, disable on sparc64 - a number of people report breakage. Probably a compiler bug, but it's quite possible that it tickles some latent kernel problem too. It still defaults to 'y' everywhere else (when enabled through EXPERIMENTAL), and Dave Jones points out that Fedora (and RHEL4) has been building with size optimizations for a long time on x86, x86-64, ia64, s390, s390x, ppc32 and ppc64. So it is really only moderately experimental, but the sparc64 breakage certainly shows that it can trigger "issues". Signed-off-by:
