Hello Andrew, all
Please see attached herein a patch to replace INITRAMFS_COMPRESSION_GZIP

Sometimes boot loaders set CPU frequency to a value outside of frequency table
present with cpufreq core. In such cases CPU might be unstable if it has to run
on that frequency for long duration of time and so its better to set it to a
frequency which is specified in freq-table. This also makes

This patch adds support for the interrupt controllers found in some
TI-Nspire models.
FIQ support was taken out to simplify the driver
code and may be added in later. Since Linux on this platform doesn't
really use FIQs, this wasn't really that important in the first
place.

The USB controller in TI-NSPIRE calculators are based off either Freescale's

Now that we create a struct acpi_device object for every ACPI
namespace node representing a device, it is not necessary to
use acpi_walk_namespace() for child device lookup in
acpi_find_child() any more. Instead, we can simply walk the
list of children of the given

Since acpi_get_child() is the only user of acpi_find_child() now,
drop the static inline definition of the former and redefine the
latter as new acpi_get_child().

Hi,
The following series of four patches (on top of current
linux-pm.git/bleeding-edge)
rework child device lookup in drivers/acpi/glue.c and related things:
[1/4] ACPI / bind: Simplify child device lookup
[2/4] PCI/ ACPI: Use acpi_find_child_device() for child device lookup
[3/4] ACPI / bind:
From: Rafael J. Wysocki
Modify acpi_preset_companion() to take a struct acpi_device pointer
instead of an ACPI handle as its second argument and redefine it as
a static inline wrapper around ACPI_COMPANION_SET() passing the
return value of acpi_find_child_device() directly as the second
argument
From: Rafael J. Wysocki
It is much more efficient to use acpi_find_child_device()
for child devices lookup in acpi_pci_find_device() and pass
ACPI_COMPANION(dev->parent) to it directly instead of obtaining
ACPI_HANDLE() of ACPI_COMPANION(dev->parent) and passing it to
acpi_find_child() which has
Commit 35f9c09fe (tcp: tcp_sendpages() should call tcp_push() once)
added an internal flag MSG_SENDPAGE_NOTLAST.
We have to ensure that MSG_MORE is also set if we set MSG_SENDPAGE_NOTLAST.
Otherwise users that check against MSG_MORE will not see it.
This fixes sendfile() on AF_ALG.

The radix tree hole searching code is only used for page cache, for
example the readahead code trying to get a a picture of the area
surrounding a fault.
It sufficed to rely on the radix tree definition of holes, which is
"empty tree slot". But this is about to change, though, as shadow
page
Changes in this revision:
o Based on suggestions from Dave Chinner and Rik van Riel, rework the
shadow entry reclaim to directly track and scan radix tree nodes
containing only shadows instead of operating on an inode level.
This adds one word to the address space (thus inode) and
Reclaim will be leaving shadow entries in the page cache radix tree
upon evicting the real page. As those pages are found from the LRU,
an iput() can lead to the inode being freed concurrently. At this
point, reclaim must no longer install shadow pages because the inode
freeing code needs to
Previously, page cache radix tree nodes were freed after reclaim
emptied out their page pointers. But now reclaim stores shadow
entries in their place, which are only reclaimed when the inodes
themselves are reclaimed. This is problematic for bigger files that
are still in use after they have a
Make struct radix_tree_node part of the public interface and provide
API functions to create, look up, and delete whole nodes. Refactor
the existing insert, look up, delete functions on top of these new
node primitives.
This will allow the VM to track and garbage collect page cache radix
tree
Provide a function that does not just delete an entry at a given
index, but also allows passing in an expected item. Delete only if
that item is still located at the specified index.
This is handy when lockless tree traversals want to delete entries as
well because they don't have to do an
shmem mappings already contain exceptional entries where swap slot
information is remembered.
To be able to store eviction information for regular page cache,
prepare every site dealing with the radix trees directly to handle
entries other than pages.
The common lookup functions will filter out
The VM maintains cached filesystem pages on two types of lists. One
list holds the pages recently faulted into the cache, the other list
holds pages that have been referenced repeatedly on that first list.
The idea is to prefer reclaiming young pages over those that have
shown to benefit from
Page cache radix tree slots are usually stabilized by the page lock,
but shmem's swap cookies have no such thing. Because the overall
truncation loop is lockless, the swap entry is currently confirmed by
a tree lookup and then deleted by another tree lookup under the same
tree lock region.
Use
This code used to have its own lru cache pagevec up until a0b8cab3
("mm: remove lru parameter from __pagevec_lru_add and remove parts of
pagevec API"). Now it's just add_to_page_cache() followed by
lru_cache_add(), might as well use add_to_page_cache_lru() directly.

Thanks for the report. However the dmesg you attached doesn't mention:
