This way we don't have to worry about the exact bit postition of the
test to leak out and any crazy propagation effects in the callers.

Currently libata statically allows only 1-block (512-byte) payload
for each TRIM command. Each payload can carry 64 TRIM ranges since
each range requires 8 bytes.
It is silly to keep doing the calculation (512 / 8) in different
places. Hence, define the new ATA_MAX_TRIM_RNUM for the result.

Currently if a WRITE SAME (16) command is issued to the SATL with
"number of blocks" that is larger than the "Maximum write same length"
(which is the maximum number of blocks per TRIM command allowed in
libata, currently 65535 * 512 / 8 blocks), the SATL will accept the
command and translate it to a TRIM command with the upper limit.
However, according to SBC (as of sbc4r11.pdf), the "device server"
should terminate the command with "Invalid field in CDB" in that case.

The bit should always be set to 1 when the requested version of
page is "changeable" because we've made it so in ata_mselect_control().
Also, it should always be set to 1 if ATA_DFLAG_D_SENSE is set (when
the requested version of page is "current" or "default").

The comment suggests we should be having an SPC-3 version descriptor
but the 0260h is the code for "SPC-2 (no version claimed)". Correct
it to 0300h so that it has the "SPC-3 (no version claimed)" descriptor.
Note that we are claiming SPC-3 version compatibility in the VERSION
field of the standard INQUIRY data. Therefore, I assume the typo was
on the code but not on the comment.

The sysfs file for the libata error handling has multiple issues
in the way it prints time stamps:
* it prints a 9-digit nanosecond value using a %06lu format string,
which drops some leading zeroes
* it converts a 64-bit jiffes value to a timespec using
jiffies_to_timespec(), which takes a 'long' argument, so the
result is wrong after a jiffies overflow (49 days).
* we try to avoid using timespec because that generally overflows
in 2038, although this particular usage is ok.
This replaces the jiffies_to_timespec call with an open-coded
implementation that gets it right.

mem_cgroup_out_of_memory() is returning "true" if it finds a TIF_MEMDIE
task after an eligible task was found, "false" if it found a TIF_MEMDIE
task before an eligible task is found.
This difference confuses memory_max_write() which checks the return
value of mem_cgroup_out_of_memory(). Since memory_max_write() wants to
continue looping, mem_cgroup_out_of_memory() should return "true" in
this case.
This patch sets a dummy pointer in order to return "true".

Per the suggestion from Michal Hocko [1], DEFERRED_STRUCT_PAGE_INIT
requires some ordering wrt other initialization operations, e.g.
page_ext_init has to happen after the whole memmap is initialized
properly.
For SPARSEMEM this requires to wait for page_alloc_init_late. Other
memory models (e.g. flatmem) might have different initialization
layouts (page_ext_init_flatmem). Currently DEFERRED_STRUCT_PAGE_INIT
depends on MEMORY_HOTPLUG which in turn
depends on SPARSEMEM || X86_64_ACPI_NUMA
depends on ARCH_ENABLE_MEMORY_HOTPLUG
and X86_64_ACPI_NUMA depends on NUMA which in turn disable FLATMEM
memory model:
config ARCH_FLATMEM_ENABLE
def_bool y
depends on X86_32 && !NUMA
so FLATMEM is ruled out via dependency maze. Be explicit and disable
FLATMEM for DEFERRED_STRUCT_PAGE_INIT so that we do not reintroduce
subtle initialization bugs

Pull Ceph updates from Sage Weil:
"This changeset has a few main parts:
- Ilya has finished a huge refactoring effort to sync up the
client-side logic in libceph with the user-space client code, which
has evolved significantly over the last couple years, with lots of
additional behaviors (e.g., how requests are handled when cluster
is full and transitions from full to non-full).
This structure of the code is more closely aligned with userspace
now such that it will be much easier to maintain going forward when
behavior changes take place. There are some locking improvements
bundled in as well.
- Zheng adds multi-filesystem support (multiple namespaces within the
same Ceph cluster)
- Zheng has changed the readdir offsets and directory enumeration so
that dentry offsets are hash-based and therefore stable across
directory fragmentation events on the MDS.
- Zheng has a smorgasbord of bug fixes across fs/ceph"
