[PATCH] uml: allow ubd devices to provide partial end blocks · 5af50f60

Jeff Dike authored Jan 20, 2005

If the file backing a ubd device is not an even blocklength, then the last
partial block is now readable, and it is padded with zeros.

[PATCH] driver model: pass pm_message_t down to pci drivers · d5ad622a

Pavel Machek authored Jan 20, 2005

This passes pm_message_t down to PCI drivers.  Ugly translation code can be
removed and this will allow PCI devices to do right thing during swsusp
snapshot -- like not unneccessarily blanking display.

Only obscure /sysfs code passes anything but 3 to pci_device_suspend,
anyway, so this is pretty close to a nop.

[PATCH] i386/x86-64: Fix SMP NMI watchdog race · 2a66bc5a

Andi Kleen authored Jan 20, 2005

Fix SMP race in NMI watchdog on i386/x86-64

Fix a long standing SMP Setup race in the NMI watchdog.  The watchdog would
tick from very early and check if all CPUs increase their timer interrupts.
For that it would check the cpu_online_map.  Now if a CPU took too long to
boot the watchdog would trigger prematurely because the CPU didn't increase
its timer count yet.

Fix is to check cpu_callin_map instead of cpu_online_map because the first is
only set when a CPU started its timer interrupt.

I fixed it on i386 and x86-64.

Description of the problem from Manpreet Singh. Thanks.

[PATCH] x86_64: fix flush race on context switch · 421f4e4a

Andi Kleen authored Jan 20, 2005

Fix a long standing race in x86-64 SMP TLB handling. When a mm is freed and
another thread exits to a lazy TLB thread (like idle) the freed user page
tables would be still kept loaded in the idle thread. When an interrupt does
a prefetch on NULL the CPU would try to follow it and read random data.

This could lead to machine checks on Opterons in some cases.

Credit goes to some unnamed debugging wizards at AMD who described the
problem. All blame to me. I did the fix based on their description.

[PATCH] fix xenU kernel crash in dmi_iterate · f39f308b

Rik van Riel authored Jan 20, 2005

In unprivileged Xen domains, all that __ioremap() does is a "return NULL",
which causes dmi_iterate() to crash the kernel at boot time.

This trivial check bails dmi_iterate() out of the loop when it finds that
the ioremap() returned a NULL pointer.

(akpm: this fix goes beyond xen - ioremap can return NULL)

[PATCH] ppc64/ppc: Cleanup PCI skipping · cd7acce7

Benjamin Herrenschmidt authored Jan 20, 2005

The g5 code has special hooks to "hide" some PCI devices when they are off.

Currently, this code involves some calls to match a pci_dev from the open
firmware node and such things that are causing some problems with the
latest version of my sungem driver who wants to do some of this in atomic
contexts.

This patch moves that to a list of struct device_node instead, which also
ends up simplifying the code.

Later, I'll go back to manipulating PCI devices in a clean way when Brian
King's PCI blocking patch gets in, but only after I change sungem again to
never call these in atomic context.  This is a 3 step transition basically

I considered removing the option completely but we have had problems in the
past with firmware bugs.  In those cases the boot option would have helped.
