RAMster implements peer-to-peer transcendent memory, allowing a "cluster"
of kernels to dynamically pool their RAM.

This patch incorporates changes transforming zcache to work with
a remote store.

In tmem.[ch], new "repatriate" (provoke async get) and "localify" (handle
incoming data resulting from an async get) routines combine with a handful
of changes to existing pamops interfaces allow the generic tmem code
to support asynchronous operations.  Also, a new tmem_xhandle struct
groups together key information that must be passed to remote tmem stores.

Zcache-main.c is augmented with a large amount of ramster-specific code
to handle remote operations and "foreign" pages on both ends of the
"remotify" protocol.  New "foreign" pools are auto-created on demand.
A "selfshrinker" thread periodically repatriates remote persistent pages
when local memory conditions allow.  For certain operations, a queue is
necessary to guarantee strict ordering as out-of-order puts/flushes can
cause strange race conditions.  Pampd pointers now either point to local
memory OR describe a remote page; to allow the same 64-bits to describe
either, the LSB is used to differentiate.  Some acrobatics must be performed
to ensure local memory is available to handle a remote persistent get,
or deal with the data directly anyway if the malloc failed.  Lots
of ramster-specific statistics are available via sysfs.

Note: Some debug ifdefs left in for now.

RAMster implements peer-to-peer transcendent memory, allowing a "cluster"

This patch copies files from drivers/staging/zcache.  RAMster compresses

leverage the zcache and tmem code directly.  Note: there are
no ramster-specific changes yet to these files.

(Why copy?  The ramster tmem.c/tmem.h changes are definitely shareable
between zcache and ramster; the eventual destination for tmem.c
is the linux lib directory.  Ramster changes to zcache are more substantial
and zcache is currently undergoing some significant unrelated changes
(including a new allocator and breaking zcache-main.c into smaller files),
so it seemed best to branch temporarily and merge later.)

staging: android-alarm: Support old drivers via preprocessor aliasing

Older out of tree drivers that were desgined to the Android Alarm
in-kernel API may not build due to the namespace collision fixed in
an earlier patch. Per Arve's suggestion, this patch provides
preprocessor macros that allow older drivers to build.

staging: r8712u: Add missing initialization and remove configuration parameter CONFIG_R8712_AP

When this driver was upgraded to the vendor 20100831 version in
commit 93c55dda092c7 et al,, one listhead initialization was missed.
This broke complete operation of the driver whenever AP mode was
enabled. This fixes https://bugs.archlinux.org/task/27996.

The configuration parameter R8712_AP is misleading as the driver cannot
function as an AP without a heavily hacked version of hostapd. Thus, it
makes sense to remove the parameter; however the code and data configured
for the option is left in.

12 years agoReduce the number of expensive division instructions done by _parse_integer()
David Howells [Thu, 9 Feb 2012 15:48:20 +0000 (15:48 +0000)]
Reduce the number of expensive division instructions done by _parse_integer()

_parse_integer() does one or two division instructions (which are slow)
per digit parsed to perform the overflow check.

Furthermore, these are particularly expensive examples of division
instruction as the number of clock cycles required to complete them may
go up with the position of the most significant set bit in the dividend:

if (*res > div_u64(ULLONG_MAX - val, base))

which is as maximal as possible.

Worse, on 32-bit arches, more than one of these division instructions
may be required per digit.

So, assuming we don't support a base of more than 16, skip the check if the
top nibble of the result is not set at this point.

staging:iio:adc:adt7310/7410 sticking plaster fix for broken event attrs.

Neither of these drivers has ever been anywhere near the iio abi.
Probably as a result of this the fact they had two event groups
each was not picked up when we restricted IIO to having only
1 event line per device (as part of the chrdev merge set).

the only element from the 'comparator' event line that isn't in the
'interrupt' one into it and kills off the 'comparator' one.

Ultimately both of these drivers belong in hwmon not IIO and are just
waiting here because I don't want to kill off a driver that may
prove useful to someone.  (Ultimately I will ask Greg to scrap
