* UHCI: don't stop at an Iso errorAlan Stern2006-08-311-1/+1
| | | | | | | | | | | Unlike other sorts of endpoint queues, Isochronous queues don't stop when an error is encountered. This patch (as772) fixes the scanning routine in uhci-hcd, to make it keep on going when it finds an Iso error.

* usb gadget: g_ether spinlock recursion fixDavid Brownell2006-08-311-14/+31
| | | | | | | | | | | | | | | The new spinlock debug code turned up a spinlock recursion bug in the Ethernet gadget driver on a disconnect path; it would show up with any UDC driver where the cancellation of active requests was synchronous, rather than e.g. delayed until a controller's completion IRQ. That recursion is fixed here by creating and using a new spinlock to protect the relevant lists.

* [IPV4]: Fix SNMPv2 "ipFragFails" counter errorWei Dong2006-08-311-0/+1

| * | [POWERPC] Fix irq enable/disable in smp_generic_take_timebasePaul Mackerras2006-08-302-5/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Eran Ben-Avi <eranpublic@yahoo.com> pointed out that the arch/ppc version of smp_generic_take_timebase disables interrupts on entry but exits without restoring them. However, both it and the arch/powerpc version have another problem, which is that they use local_irq_disable/enable rather than local_irq_save/restore, and they are called with interrupts disabled. This fixes both problems; it changes a return to a break in the arch/ppc version, and changes both versions to use local_irq_save/restore. Signed-off-by: Paul Mackerras <paulus@samba.org>
| * | [POWERPC] Fix problem with time not advancing on 32-bit platformsPaul Mackerras2006-08-302-21/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This fixes a problem introduced in 5db9fa9593e2ff69f2b95f9d59229dc4faaa564d. The last_jiffy per-cpu variable is only 32 bits on 32-bit machines, but it was being compared with a 64-bit quantity (tb_next_jiffy), which resulted in time not advancing. This fixes it by changing last_jiffy to be 64 bits on all platforms. With this, we no longer need tb_last_stamp as a 32-bit version of tb_last_jiffy, so this gets rid of tb_last_stamp and we just use tb_last_jiffy instead. This also fixes a bug when the boot cpu is not online, because using tb_last_stamp could have caused the wrong timebase origin value to be used when calculating the time of day.

This enables the mpic code to deal with mpic controllers with different register layouts and hardware behaviours. This introduces CONFIG_MPIC_WEIRD. For boards with non standard mpic controllers, select CONFIG_MPIC_WEIRD and add its hardware information in the mpic_infos[] array. TSI108/109 PIC takes the first index of weird hardware information table. :) The table can be extended. The Tsi108/109 PIC looks like standard OpenPIC but, in fact, is different in register mapping and behavior. The patch does not affect the behavior of standard mpic. If CONFIG_MPIC_WEIRD is not defined, the code is essentially identical to the current code. [benh@kernel.crashing.org: This patch is a slightly cleaned up version of Zang Roy's support for the TSI108 MPIC variant. It also fixes up MPC7448_hpc2 to use the new version of the type macros and changes the way MPIC is selected in Kconfig to better match what is done for other system devices. ] Signed-off-by: Roy Zang <tie-fei.zang@freescale.com> Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by: Paul Mackerras <paulus@samba.org>

* | | | [PATCH] Missing PCI id update for VIA IDEAlan Cox2006-08-301-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The following change from -mm is important to 2.6.18 (actually to 2.6.17 but its too late for that). This was contributed over three months ago by VIA to Bartlomiej and nothing happened. As a result the new chipset is now out and Linux won't run on it. By the time 2.6.18 is finalised this will be the defacto standard VIA chipset so support would be a good plan. Tested in -mm for a while, its essentially a PCI ident update but for the bridge chip because VIA do things in weird ways. Signed-off-by: Linus Torvalds <torvalds@osdl.org>
* | | | [PATCH] x86_64: Don't write out segments from vsyscall32 DSO if it is not mappedSuleiman Souhlal2006-08-301-26/+31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It's possible to get an invalid page fault in kernel mode when we try to write out segments from vsyscall32 when dumping core for a 32bit process if the vsyscall32 DSO is not mapped in its address space (which can happen if, for example, ulimit -v 100 is run).

On those machines don't use MMCONFIG. This also adds a new pci=mmconf parameter to override the blacklist.
