While looking to the report by Coverity in ipmi, I came across the
following issue:
The IPMI message handler relies on two defines which are the same -one in
include/linux/ipmi.h
#define IPMI_NUM_CHANNELS 0x10
and one in drivers/char/ipmi/ipmi_msghandler.
#define IPMI_MAX_CHANNELS 16
These are used interchangeably in ipmi_msghandler.c, but since the array
addr->channels[] is of size IPMI_MAX_CHANNELS, I have made a patch that
uses IPMI_MAX_CHANNELS for all the checks for the array index.
NOTE: You could probably remove the line that defines IPMI_NUM_CHANNELS
from ipmi.h, or move IPMI_MAX_CHANNELS to ipmi.h

It's due to

With Eric's "i386: Add a temporary to make put_user more type safe" patch we

drivers/char/ip2main.c:2911: warning: assignment makes integer from pointer without a cast

This ioctl is copying the kernel virtual address of a large number of

Rather than fixing the warnings, I think we'll just nuke that code.
The patch also fixes a couple of `defined but not used' warnings.

Change locking in the new tty buffering facility from using tty->read_lock,
which is currently ignored by drivers and thus ineffective. New locking
uses a new tty buffering specific lock enforced centrally in the tty
buffering code.
Two drivers (esp and cyclades) are updated to use the tty buffering
functions instead of accessing tty buffering internals directly. This is
required for the new locking to work.
Minor checks for NULL buffers added to

The patch implements cpu topology exportation by sysfs.
Items (attributes) are similar to /proc/cpuinfo.
1) /sys/devices/system/cpu/cpuX/topology/physical_package_id:
represent the physical package id of cpu X;
2) /sys/devices/system/cpu/cpuX/topology/core_id:
represent the cpu core id to cpu X;
3) /sys/devices/system/cpu/cpuX/topology/thread_siblings:
represent the thread siblings to cpu X in the same core;
4) /sys/devices/system/cpu/cpuX/topology/core_siblings:
represent the thread siblings to cpu X in the same physical package;
To implement it in an architecture-neutral way, a new source file,
driver/base/topology.c, is to export the 5 attributes.
If one architecture wants to support this feature, it just needs to
implement 4 defines, typically in file include/asm-XXX/topology.h.
The 4 defines are:
#define topology_physical_package_id(cpu)
#define topology_core_id(cpu)
#define topology_thread_siblings(cpu)
#define topology_core_siblings(cpu)
The type of **_id is int.
The type of siblings is cpumask_t.
To be consistent on all architectures, the 4 attributes should have
deafult values if their values are unavailable. Below is the rule.
1) physical_package_id: If cpu has no physical package id, -1 is the
default value.
2) core_id: If cpu doesn't support multi-core, its core id is 0.
3) thread_siblings: Just include itself, if the cpu doesn't support
HT/multi-thread.
4) core_siblings: Just include itself, if the cpu doesn't support
multi-core and HT/Multi-thread.
So be careful when declaring the 4 defines in include/asm-XXX/topology.h.
If an attribute isn't defined on an architecture, it won't be exported.
Thank Nathan, Greg, Andi, Paul and Venki.
The patch provides defines for i386/x86_64/ia64.

mdu_array_info_t->size is 'int', which isn't big enough for the size (in KB of
each component in) some arrays.
So rather than a random overflow, set size to -1 when it cannot be set
correctly.
To update aspect on an array, userspace will sometimes:
get_array_info
change one field
set_array_info
in this case, we don't want the '-1' in 'size' to change to size, or look like
a size change at all. So test for that in update_array_info.

As 'array_size' is a 'sector_t', it may overflow inappropriately when shifted
10 bits. So We should cast it to a loff_t first.
There are two places with this problem, but the second (in update_raid_disks)
isn't needed so just remove it:
The only personality that handles ->reshape currently is raid1,
and it doesn't change the size of the array.
When added for raid5/6, reshape again won't change the size of the array,
at least not straight away.
This code might be need for reshaping 'linear' but linear->shape,
if implemented, should probably do the i_size_write itself.
