Jean Delvare c3813d6af1 i2c: Get rid of struct i2c_client_address_data
Struct i2c_client_address_data only contains one field at this point,
which makes its usefulness questionable. Get rid of it and pass simple
address lists around instead.

Geert Uytterhoeven 59d309f9c8 kgdb: Replace strstr() by strchr() for single-character needles
Some versions of gcc replace calls to strstr() with single-character
"needle" string parameters by calls to strchr() behind our back.
This causes linking errors if strchr() is defined as an inline function
in <asm/string.h> (e.g. on m68k, which BTW doesn't have kgdb support).

Prevent this by explicitly calling strchr() instead.

James Bottomley cc9b2e9f66 [SCSI] enclosure: fix oops while iterating enclosure_status array
Based on patch originally by Jeff Mahoney <jeffm@suse.com>

 enclosure_status is expected to be a NULL terminated array of strings
 but isn't actually NULL terminated. When writing an invalid value to
 /sys/class/enclosure/.../.../status, it goes off the end of the array
 and Oopses.


Fix by making the assumption true and adding NULL at the end.

Linus Torvalds d39b7dd1dc sgi-gru: decrapfiy options_write() function
Not a single line of actual code in the function was really
fundamentally correct.

Problems ranged from lack of proper range checking, to removing the last
character written (which admittedly is usually '\n'), to not accepting
hex numbers even though the 'show' routine would show the data in that
format.

This tries to do better.

Jean Delvare b835d7fbd5 max6875: Discard obsolete detect method
There is no point in implementing a detect callback for the MAX6875, as
this device can't be detected. It was there solely to handle "force"
module parameters to instantiate devices, but now we have a better sysfs
interface that can do the same.

So we can get rid of the ugly module parameters and the detect callback.
This basically divides the binary module size by 2.

Sebastian Heutling f0d83679a8 eeprom/at25: bugfix "not ready" timeout after write
Under certain circumstances msleep(1) within the loop, which waits for the
EEPROM to be finished, might take longer than the timeout.  On the next
loop the status register might now return to be ready and therefore the
loop finishes.  The following check now tests if a timeout occurred and if
so returns an error although the device reported it was ready.

This fix replaces testing the occurrence of the timeout by testing the
"not ready" bit in the status register.

Jack Steiner cd1334f03f gru: bug fixes for GRU exception handling
Bug fixes for GRU exception handling.  Additional fields from the CBR must
be returned to the user to allow the user to correctly diagnose GRU
exceptions.

Handle endcase in TFH TLB miss handling.  Verify that TFH actually
indicates a pending exception.

Mel Gorman 6484eb3e2a page allocator: do not check NUMA node ID when the caller knows the node is valid
Callers of alloc_pages_node() can optionally specify -1 as a node to mean
"allocate from the current node".  However, a number of the callers in
fast paths know for a fact their node is valid.  To avoid a comparison and
branch, this patch adds alloc_pages_exact_node() that only checks the nid
with VM_BUG_ON().  Callers that know their node is valid are then
converted.

Wolfram Sang 4b364f230a i2c/chips: Move max6875 to drivers/misc/eeprom
This driver only reads the user EEPROM of that chip, so we can move it
to the eeprom-directory in order to further clean up (and later remove)
drivers/i2c/chips.

The Kconfig text was updated to match the current functionality,
dropping the meanwhile obsoleted parts.

Defconfigs have been adapted.

Yinghai Lu 5e43754fd9 [SCSI] ses: fix problems caused by empty SES provided name
We use the name provided by SES to name objects.  An empty name is
legal in SES but causes problems in our generic device hierarchy.  Fix
this by falling back to a number if the name is either NULL or empty.

Also fix a secondary bug spotted in that dev_set_name(dev, name) uses
a string format and so would go wrong if name contained a '%'.

For an upcoming distro release, we need to have the xp kernel module
loadable even when not on UV equipment.  The xpc module will not load.
This will allow one set of modules dependent upon xp to work on either UV
or non-UV equipment.
