[IA64] disable preemption in udelay() · f5899b5d

John Hawkes authored Dec 16, 2005

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.

[PATCH] Au1550 AC'97 OSS driver spinlock fixes · 7b666653

Sergei Shtylylov authored Dec 15, 2005

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).

[PATCH] IPMI oops fix · 7767e126

Paolo Galtieri authored Dec 15, 2005

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.

[PATCH] reiserfs: close open transactions on error path · 24996049

Jeff Mahoney authored Dec 14, 2005

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

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.

Move size optimization option outside of EMBEDDED menu, mark it EXPERIMENTAL · c45b4f1f

Linus Torvalds authored Dec 14, 2005

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".
