powerpc/legacy_serial: Bail if reg-offset/shift properties are present

The legacy serial driver does not work with an 8250 type UART that is
described in the device tree with the reg-offset and reg-shift
properties.  This change makes legacy_serial ignore these devices.

V4L/DVB (8108): Fix open/close race in saa7134

The saa7134 driver uses a (non-atomic) variable in an attempt to
only allow one opener of the device (how it deals with sending
the fd over unix sockets I don't know).

Unfortunately, the release function first decrements this variable,
and THEN goes on to disable more of the device. This allows for
a race where another opener of the device comes in after the decrement of
the variable, configures the hardware just to then see the hardware
be disabled by the rest of the release function.

This patch makes the release function use the same lock as the open
function to protect the hardware as well as the variable (which now
at least has some locking to protect it).

V4L/DVB (8040): soc-camera: remove soc_camera_host_class class

Devices can either be class devices or bus devices, not both at the
same time. Soc-camera host devices usually have a platform device as
their parent. Trying to also register them with a class crashes the
kernel, when linked statically. Interestingly, it works when built
as a module. Thanks to Paulius Zaleckas for reporting.

V4L/DVB (8029): Improve error message at tda1004x_attach

When an error occurs at firmware loading, sometimes, tda1004x stops answering.
Instead of reporting such error, attach code were assuming that the device were
answering an invalid ID (0xff). This can be seen when enabling debug options:

tda1004x: tda1004x_read_byte: reg=0x0
tda1004x: tda1004x_read_byte: error reg=0x0, ret=-5

Now, instead of reporting an invalid ID, it will report the correct error:

tda10046: chip is not answering. Giving up.
saa7133[0]/dvb: failed to attach tda10046
saa7133[0]/dvb: frontend initialization failed

A possible improvement would be trying to reset the device.

V4L/DVB (8028): Improve error messages for tda1004x attach

A fresh copy of v.29 firmware, using get_firmware, is leading to an invalid
firmware:

tda1004x: Error during firmware upload
tda1004x: found firmware revision ff -- invalid
tda1004x: firmware upload failed

Sometimes, loading/unloading this firmware makes tda1004x to return an invalid
ID. However, there were no printk messages to help to identify what were the
cause for the error.

With this patch, it will now print:

[GFS2] fix gfs2 block allocation (cleaned up)

This patch fixes bz 450641.

This patch changes the computation for zero_metapath_length(), which it
renames to metapath_branch_start(). When you are extending the metadata
tree, The indirect blocks that point to the new data block must either
diverge from the existing tree either at the inode, or at the first
indirect block. They can diverge at the first indirect block because the
inode has room for 483 pointers while the indirect blocks have room for
509 pointers, so when the tree is grown, there is some free space in the
first indirect block. What metapath_branch_start() now computes is the
height where the first indirect block for the new data block is located.
It can either be 1 (if the indirect block diverges from the inode) or 2
(if it diverges from the first indirect block).

The ioapic acknowledge path translates interrupt vectors to irqs.  It

redirection table entry containing the vector.  That fails however if the

KVM: MMU: Fix oops on guest userspace access to guest pagetable

KVM has a heuristic to unshadow guest pagetables when userspace accesses
them, on the assumption that most guests do not allow userspace to access
pagetables directly. Unfortunately, in addition to unshadowing the pagetables,
it also oopses.

This never triggers on ordinary guests since sane OSes will clear the
pagetables before assigning them to userspace, which will trigger the flood
heuristic, unshadowing the pagetables before the first userspace access. One
particular guest, though (Xenner) will run the kernel in userspace, triggering
the oops.  Since the heuristic is incorrect in this case, we can simply
remove it.

12 years agoKVM: MMU: large page update_pte issue with non-PAE 32-bit guests (resend)

KVM: MMU: large page update_pte issue with non-PAE 32-bit guests (resend)

kvm_mmu_pte_write() does not handle 32-bit non-PAE large page backed
guests properly. It will instantiate two 2MB sptes pointing to the same
physical 2MB page when a guest large pte update is trapped.

Instead of duplicating code to handle this, disallow directory level
updates to happen through kvm_mmu_pte_write(), so the two 2MB sptes
emulating one guest 4MB pte can be correctly created by the page fault
handling path.

KVM: MMU: Fix rmap_write_protect() hugepage iteration bug

rmap_next() does not work correctly after rmap_remove(), as it expects
the rmap chains not to change during iteration.  Fix (for now) by restarting
iteration from the beginning.

KVM: close timer injection race window in __vcpu_run

If a timer fires after kvm_inject_pending_timer_irqs() but before
local_irq_disable() the code will enter guest mode and only inject such
timer interrupt the next time an unrelated event causes an exit.

It would be simpler if the timer->pending irq conversion could be done
with IRQ's disabled, so that the above problem cannot happen.

For now introduce a new vcpu requests bit to cancel guest entry.

12 years agoKVM: Fix race between timer migration and vcpu migration
Marcelo Tosatti [Fri, 6 Jun 2008 19:37:35 +0000]
KVM: Fix race between timer migration and vcpu migration

A guest vcpu instance can be scheduled to a different physical CPU
between the test for KVM_REQ_MIGRATE_TIMER and local_irq_disable().

If that happens, the timer will only be migrated to the current pCPU on
the next exit, meaning that guest LAPIC timer event can be delayed until
a host interrupt is triggered.

Fix it by cancelling guest entry if any vcpu request is pending.  This
has the side effect of nicely consolidating vcpu->requests checks.
