We recently found a problem that was causing memory corruption during boot on IBM POWER5 machines. The problem was that the if you have a USB keyboard and it is set to the input device for the firmware, it will still be active when the kernel is started. That means that the OHCI controller has pointers to various memory areas that it polls for transfers to do. When we start using that same memory in the kernel, bad things can happen. (This isn't a problem on powermacs because the Apple OF implements a "quiesce" call which turns off all the devices it is using.) This patch fixes the problem by calling the Open Firmware "close" method for the input device. Stephen Rothwell and I have verified that doing this fixes the problem on the POWER5 machine where we observed it. I verified that this patch doesn't cause any problems on powermacs. I think this patch should go into 2.6.10 since it fixes a nasty memory corruption bug that can cause rather subtle and hard-to-diagnose problems during boot. (The symptom on the POWER5 machine with the particular kernel that we were using was that reading /proc/net/tcp would oops, due to one of the pointers in tcp_ehash being corrupted.)

alloc_dma_rcv_ctx is called in interrupt and Kernel Spinlock debugging code cribs about it via "Debug: sleeping function called in interrupt context". See sample stack traces below. The patch below corrects ohci1394.c to use GFP_ATOMIC instead of GFP_KERNEL. Tested to work fine with 2 different Camcorder devices for fairly long periods and connect/disconnects.

The PowerMac specific sleep code in the OHCI USB driver used to call disable/enable irq, which is no longer necessary and actually clashes with the calls to free/request_irq that the common OHCI code now does, thus causing WARN_ON's to trigger each time a PowerBook is woken up from sleep.

Santiago Leon authored
There's a chance that the receive buffers are being consumed at the same rate as they are being replenished in ibmveth_replenish_task()... Meanwhile, the calls to schedule_replenishing() from ibmveth_poll() won't schedule another replenishing cycle (because the not_replenishing flag is zero), starving the buffers and making the adapter unable to receive packets unless the module is reloaded... Here's a small patch that will fix it by scheduling another replenishing task after toggling the not_replenishing flag.

Marc Singer authored
Patch from Marc Singer Add support for the LPD7a40x implementation of the SMC91x ethernet controller. This patch exists to work around a mismatch between the way the LH7a40x CPUs handle chip selects and what the ethernet controller expects. This patch has been revised to eliminate masking of interrupts. The concessions are that a) the ISR must perform an IOBARRIER before the first access to the chip, just in case the interrupt occurred while the driver was writing to the chip b) other drivers that use the same chip select region as the SMC chip must perform a similar IOBARRIER at the top of their ISRs.

Some time ago, a patch was merged that removed pci_save_state() and pci_restore_state() from various ALSA drivers. That patch also added pci_restore_state() to sound/core/init.c but didn't add pci_save_state() anywhere. This is needed since the core pci handling doesn't do this for us anymore. My laptop doesn't resume (gets what I assume is an ACPI timeout and hangs solid) without this small obvious patch.

We have to load the bigkernel second TLB entry on secondary processors before we move over the use the kernel trap table. Otherwise we can take a TLB miss somewhere in the post-4MB area and the TLB handler is not prepared to service that. The case that usually occurs is the prom_set_trap_table call made by trampoline.S, since p1275buf usually sits very near the end of the kernel image. It worked by luck most of the time as long as p1275buf sits within a single page since earlier code running in trampoline.S forced that TLB entry to be loaded by the OBP TLB miss handler. This was not fun to figure out. Signed-off-by: David S. Miller <davem@davemloft.net>

Patch from Ben Dooks A simple divide is not enough for the s3c2410 default timer code, due to most clocks not being a nice multiple of usecs. This update changes the calculation of the usec to use multipliers and shifts to effect a fast divide by a non-integer number.

sysfs_dir_close did not free the "cursor" sysfs_dirent used for keeping track of position in the list of sysfs_dirent nodes. Consequently, doing a "find /sys" would leak a sysfs_dirent for each of the 1140 directories in my /sys tree, or about 36kB each time. From: "Adam J.

proc_pid_status dereferences pointers in the task structure even if the task is already dead. This is probably the reason for the oops described in http://bugme.osdl.org/show_bug.cgi?id=3812 The attached patch removes the pointer dereferences by using pid_alive() for testing that the task structure contents is still valid before dereferencing them. The task structure itself is guaranteed to be valid - we hold a reference count.
