When loading symbols in a data mapping, ABS symbols (which has a value
of SHN_ABS in its st_shndx) failed at elf_getscn(). And it marks the

The driver has both SPI and I2C pieces. The appropriate pieces are built based
on whether SPI and/or I2C is/are enabled. However, it was only checking if I2C
was built-in, never if it was built as a module. This patch checks for either
since building both this driver and I2C as modules is possible.

Hi all,
Today's linux-next merge of the arm-soc tree got a conflict in
arch/arm/mach-nomadik/board-nhk8815.c between commit 1cd2fc449091 ("ARM:
nomadik: fixup some FSMC merge problems") from the l2-mtd tree, commits
bb16bd9b9da4 ("pinctrl/nomadik: move the platform data header") from the
pinctrl a
ARP traffic passing through a bridge and out via the bond (when the bond is a
port of the bridge) should not have its source MAC address adjusted by the
receive load balance code in rlb_arp_xmit.

Memory fragmentation introduced by ballooning might reduce significantly
the number of 2MB contiguous memory blocks that can be used within a guest,
thus imposing performance penalties associated with the reduced number of
transparent huge pages that could be used by the guest workload.
This patch
This patch overhauls struct address_space.assoc_mapping renaming it to
address_space.private_data and its type is redefined to void*.
By this approach we consistently name the .private_* elements from
struct address_space as well as allow extended usage for address_space
association with other data
The PATCH "mm: introduce compaction and migration for virtio ballooned pages"
hacks around putback_lru_pages() in order to allow ballooned pages to be
re-inserted on balloon page list as if a ballooned page was like a LRU page.
As ballooned pages are not legitimate LRU pages, this patch introduces

This patch
This patch introduces a new set of vm event counters to keep track of
ballooned pages compaction activity.
