-From: Takahisa Tanaka <mc74hc00@gmail.com>
-Date: Wed, 14 Nov 2012 20:21:26 +0900
-Subject: [PATCH] sp5100_tco: Add SB8x0 chipset support
-
-The current sp5100_tco driver only supports SP5100/SB7x0 chipset, doesn't
-support SB8x0 chipset, because current sp5100_tco driver doesn't know that the
-offset address for watchdog timer was changed from SB8x0 chipset.
-
-The offset address of SP5100 and SB7x0 chipsets are as follows, quote from the
-AMD SB700/710/750 Register Reference Guide(Page 164) and the AMD SP5100
-Register Reference Guide(Page 166).
-
- WatchDogTimerControl 69h
- WatchDogTimerBase0 6Ch
- WatchDogTimerBase1 6Dh
- WatchDogTimerBase2 6Eh
- WatchDogTimerBase3 6Fh
-
-In contrast, the offset address of SB8x0 chipset is as follows, quote from
-AMD SB800-Series Southbridges Register Reference Guide(Page 147).
-
- WatchDogTimerEn 48h
- WatchDogTimerConfig 4Ch
-
-So, In the case of SB8x0 chipset, sp5100_tco reads meaningless MMIO
-address(for example, 0xbafe00) from wrong offset address, and the following
-message is logged.
-
- SP5100 TCO timer: mmio address 0xbafe00 already in use
+ dev->watchdog_timeo = RTL8169_TX_TIMEOUT;
+
+[PATCH] SCSI: Don't attempt to send extended INQUIRY command if skip_vpd_pages is set
-With this patch, sp5100_tco driver supports SB8x0 chipset, and can avoid
-iomem resource conflict.
+If a device has the skip_vpd_pages flag set we should simply fail the
+scsi_get_vpd_page() call.

+
+David Vrabel identified a regression when using automatic NUMA balancing
+under Xen whereby page table entries were getting corrupted due to the
+use of native PTE operations. Quoting him
+
+ Xen PV guest page tables require that their entries use machine
+ addresses if the preset bit (_PAGE_PRESENT) is set, and (for
+ successful migration) non-present PTEs must use pseudo-physical
+ addresses. This is because on migration MFNs in present PTEs are
+ translated to PFNs (canonicalised) so they may be translated back
+ to the new MFN in the destination domain (uncanonicalised).
+
+ pte_mknonnuma(), pmd_mknonnuma(), pte_mknuma() and pmd_mknuma()
+ set and clear the _PAGE_PRESENT bit using pte_set_flags(),
+ pte_clear_flags(), etc.
+
+ In a Xen PV guest, these functions must translate MFNs to PFNs
+ when clearing _PAGE_PRESENT and translate PFNs to MFNs when setting
+ _PAGE_PRESENT.
+
+His suggested fix converted p[te|md]_[set|clear]_flags to using
+paravirt-friendly ops but this is overkill. He suggested an alternative of
+using p[te|md]_modify in the NUMA page table operations but this is does
+more work than necessary and would require looking up a VMA for protections.
+
+This patch modifies the NUMA page table operations to use paravirt friendly
+operations to set/clear the flags of interest. Unfortunately this will take
+a performance hit when updating the PTEs on CONFIG_PARAVIRT but I do not
+see a way around it that does not break Xen.

-Subject: [PATCH] PCI: Add GPL license for drivers/pci/ioapic module
-
-Config PCI_IOAPIC turned into a tristate in commit b95a7bd70046, but no
-module license is specified. This adds the missing module license.

-1.7.6.5

-From: Dave Chinner <dchinner@redhat.com>

-There is a logic inversion in xfssyncd_worker() which means that the
-log is not periodically forced or idled correctly. This means that
-metadata changes aggregated in memory do not get flushed in a timely
-manner, and hence if filesystem is not cleanly unmounted those
-changes can be lost. This loss can manifest itself even hours after
-the changes were made if the filesystem is left to idle without a
-sync() occurring between the last modification and the
-crash/shutdown occuring.
