| * [IA64] fix nohalt boot optionKen Chen2005-08-08
| | | | | | | | | | | | | | | | | | | | | | | | this changeset broke the "nohalt" kernel boot option. 8df5a500a3e97f7811cdce0f553ca1917ccd4220 default_idle() is looking at new variable can_do_pal_halt. However, that variable did not get cleared upon "nohalt" boot option. Result is that "nohalt" option is ignored until perfmon is exercised.

* | [NET]: Fix memory leak in sys_{send,recv}msg() w/compatAndrew Morton2005-08-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | From: Dave Johnson <djohnson+linux-kernel@sw.starentnetworks.com> sendmsg()/recvmsg() syscalls from o32/n32 apps to a 64bit kernel will cause a kernel memory leak if iov_len > UIO_FASTIOV for each syscall! This is because both sys_sendmsg() and verify_compat_iovec() kmalloc a new iovec structure. Only the one from sys_sendmsg() is free'ed. I wrote a simple test program to confirm this after identifying the problem: http://davej.org/programs/testsendmsg.c Note that the below fix will break solaris_sendmsg()/solaris_recvmsg() as it also calls verify_compat_iovec() but expects it to malloc internally.

This function is a mere wrapper on x86 and friends, however on some others it already exists, is added in this patch (alpha, arm, ppc, ppc64) or still needs to be provided (parisc -- where is its pcibios_resource_to_bus() ?).

* | [PATCH] PCI: restore BAR values after D3hot->D0 for devices that need itJohn W. Linville2005-08-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some PCI devices (e.g. 3c905B, 3c556B) lose all configuration (including BARs) when transitioning from D3hot->D0. This leaves such a device in an inaccessible state. The patch below causes the BARs to be restored when enabling such a device, so that its driver will be able to access it. The patch also adds pci_restore_bars as a new global symbol, and adds a correpsonding EXPORT_SYMBOL_GPL for that. Some firmware (e.g. Thinkpad T21) leaves devices in D3hot after a (re)boot. Most drivers call pci_enable_device very early, so devices left in D3hot that lose configuration during the D3hot->D0 transition will be inaccessible to their drivers. Drivers could be modified to account for this, but it would be difficult to know which drivers need modification. This is especially true since often many devices are covered by the same driver. It likely would be necessary to replicate code across dozens of drivers. The patch below should trigger only when transitioning from D3hot->D0 (or at boot), and only for devices that have the "no soft reset" bit cleared in the PM control register. I believe it is safe to include this patch as part of the PCI infrastructure. The cleanest implementation of pci_restore_bars was to call pci_update_resource. Unfortunately, that does not currently exist for the sparc64 architecture. The patch below includes a null implemenation of pci_update_resource for sparc64. Some have expressed interest in making general use of the the pci_restore_bars function, so that has been exported to GPL licensed modules. Signed-off-by: John W.

First these CPUs entered into xmon by IPI callback and then got a soft-reset exception and re-entered into xmon again. The first CPU which re-entered into xmon got the output lock and made into xmon successfully without unlocking. Hence, the next CPU(s) which re-entered into xmon try to acquire a lock (get_output_lock). Therefore, we can not view state of those CPU(s).

* [PATCH] ppc64: POWER 4 fails to boot with NUMAMike Kravetz2005-08-02
| | | | | | | | | | | | | | | | | If CONFIG_NUMA is set, some POWER 4 systems will fail to boot. This is because of special processing needed to handle invalid node IDs (0xffff) on POWER 4. My previous patch to handle memory 'holes' within nodes forgot to add this special case for POWER 4 in one place. In reality, I'm not sure that configuring the kernel for NUMA on POWER 4 makes much sense. Are there POWER 4 based systems with NUMA characteristics that are presented by the firmware? But, distros want one kernel for all systems so NUMA is on by default in their kernels. The patch handles those cases.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | There was a scheduling problem of the m32r SMP kernel; A process rarely stopped and gave no responding but the other process have been handled by the other CPU still lives, then if we did something in the other terminal or something like that, the stopped process came back to life and continued its operation... (ex. LMbench: lat_sig) In the m32r SMP kernel, a local-timer event is delivered by using an IPI(inter processor interrupts); LOCAL_TIMER_IPI. And a function smp_send_timer() is prepared to send the LOCAL_TIMER_IPI from the current CPU to the other CPUs. The funtion smp_send_timer() was placed and used in do_IRQ() in former times (before 2.6.10-rc3-mm1 kernel), however, it was unintentionally removed when arch/m32r/kernel/irq.c was modified to employ the generic hardirq framework (CONFIG_GENERIC_HARDIRQ) in my previous patch.
