[PATCH] syscall class hookup for all normal targets

2006-09-12T07:04:40Z

Take default arch/*/kernel/audit.c to lib/, have those with special needs (== biarch) define AUDIT_ARCH in their Kconfig. Signed-off-by: Al Viro

[TEXTSEARCH]: Fix Boyer Moore initialization bug

2006-08-22T21:33:58Z

The pattern is set after trying to compute the prefix table, which tries to use it. Initialize it before calling compute_prefix_tbl, make compute_prefix_tbl consistently use only the data from struct ts_bm and remove the now unnecessary arguments.

[PATCH] disable debugging version of write_lock()

2006-08-06T15:57:46Z

We've confirmed that the debug version of write_lock() can get stuck for long enough to cause NMI watchdog timeouts and hence a crash. We don't know why, yet. Disable it for now. Also disable the similar read_lock() code. Just in case. Thanks to Dave Olson for reporting and testing. Acked-by: Ingo Molnar Cc: Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

PCI: docking station: remove dock uevents

2006-08-03T20:20:06Z

Remove uevent dock notifications. There are no consumers of these events at present, and uevents are likely not the correct way to send this type of event anyway. Until I get some kind of idea if anyone in userspace cares about dock events, I will just not send any. Signed-off-by: Kristen Carlson Accardi Signed-off-by: Greg Kroah-Hartman

[PATCH] Fix ppc32 zImage inflate

2006-07-31T20:28:37Z

The recent zlib update (commit 4f3865fb57a04db7cca068fed1c15badc064a302) broke ppc32 zImage decompression as it tries to decompress to address zero and the updated zlib_inflate checks that strm->next_out isn't a null pointer. This little patch fixes it.

[PATCH] let the the lockdep options depend on DEBUG_KERNEL

2006-07-15T04:53:55Z

The lockdep options should depend on DEBUG_KERNEL since: - they are kernel debugging options and - they do otherwise break the DEBUG_KERNEL menu structure Signed-off-by: Adrian Bunk Acked-by: Ingo Molnar Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[PATCH] Convert idr's internal locking to _irqsave variant

2006-07-15T04:53:54Z

Currently, the code in lib/idr.c uses a bare spin_lock(&idp->lock) to do internal locking. This is a nasty trap for code that might call idr functions from different contexts; for example, it seems perfectly reasonable to call idr_get_new() from process context and idr_remove() from interrupt context -- but with the current locking this would lead to a potential deadlock. The simplest fix for this is to just convert the idr locking to use spin_lock_irqsave(). In particular, this fixes a very complicated locking issue detected by lockdep, involving the ib_ipoib driver's priv->lock and dev->_xmit_lock, which get involved with the ib_sa module's query_idr.lock.
