smsc-ircc2 - avoid closing network device when suspending; just release
interrupt and disable DMA ourselves. Also make sure to reset chip when
resuming.

This patch exports modalias for ccw devices.
So you can do:
modprobe `echo /sys/device/path_to_device/modalias`
and the proper driver will automatically be loaded by userspace.

Update SMC91x driver for m32r.
- Remove needless NONCACHE_OFFSET adjustment.
> [PATCH 2.6.14-rc4] m32r: NONCACHE_OFFSET in _port2addr
> Change _port2addr() not to add NONCACHE_OFFSET.
> Adding NONCACHE_OFFSET requires needless address adjusting by a driver
> using ioremap() like a SMC91x driver.

cpufreq entries in sysfs should only be populated when CPU is online state.
When we either boot with maxcpus=x and then boot the other cpus by echoing
to sysfs online file, these entries should be created and destroyed when
CPU_DEAD is notified. Same treatement as cache entries under sysfs.
We place the processor in the lowest frequency, so hw managed P-State
transitions can still work on the other threads to save power.
Primary goal was to just make these directories appear/disapper dynamically.
There is one in this patch i had to do, which i really dont like myself but
probably best if someone handling the cpufreq infrastructure could give
this code right treatment if this is not acceptable. I guess its probably
good for the first cut.
- Converting lock_cpu_hotplug()/unlock_cpu_hotplug() to disable/enable preempt.
The locking was smack in the middle of the notification path, when the
hotplug is already holding the lock. I tried another solution to avoid this
so avoid taking locks if we know we are from notification path. The solution
was getting very ugly and i decided this was probably good for this iteration
until someone who understands cpufreq could do a better job than me.
(akpm: export cpucontrol to GPL modules: drivers/cpufreq/cpufreq_stats.c now
does lock_cpu_hotplug())

Some modules creating sysfs entries under /sys/devices/system/cpu/cpuX/
need to know the parent sysfs entry to make devices under them. This will
just return the sysfs entry for a given cpu.
sysfs entries showing under each cpu sysfs can be easily created if such
entries can be created by registering a sysfs driver for cpuclass. The
issue is when the entry is created the CPU may not be online, hence we
would need to defer the creation until the online notification comes.
Current users: cache entries for Intel CPU's and cpufreq subsystem.

This patch fixes an issue reported by Coverity in serial/serial_core.c
Error reported: Variable "&((info)->tty)->flags" tracked as NULL was passed to a
function that dereferences it.
The later statements in the function assumes 'info->tty != NULL', so this
check is not necessary. Probably a 'BUG_ON(info->tty == NULL)' can be added.

ata_pci_init_one() receives an array of struct ata_port_info. Recent
updates to the code had always obtained port information from
array element 0, rather than array element N.
Change to avoid hardcoding port_info[0], thereby restoring proper
hardware information to secondary legacy ports.

The second argument to ata_qc_complete() was being used for two
purposes: communicate the ATA Status register to the completion
function, and indicate an error. On legacy PCI IDE hardware, the latter
is often implicit in the former. On more modern hardware, the driver
often completely emulated a Status register value, passing ATA_ERR as an
indication that something went wrong.
Now that previous code changes have eliminated the need to use drv_stat
arg to communicate the ATA Status register value, we can convert it to a
mask of possible error classes.
This will lead to more flexible error handling in the future.

This basically keeps up from having to extern __kmalloc_section_memmap().
The vaddr_in_vmalloc_area() helper could go in a vmalloc header, but that
header gets hard to work with, because it needs some arch-specific macros.
Just stick it in here for now, instead of creating another header.

This adds generic memory add/remove and supporting functions for memory
hotplug into a new file as well as a memory hotplug kernel config option.

Remove PageReserved() calls from core code by tightening VM_RESERVED
handling in mm/ to cover PageReserved functionality.
PageReserved special casing is removed from get_page and put_page.
All setting and clearing of PageReserved is retained, and it is now flagged
in the page_alloc checks to help ensure we don't introduce any refcount
based freeing of Reserved pages.
MAP_PRIVATE, PROT_WRITE of VM_RESERVED regions is tentatively being
deprecated. We never completely handled it correctly anyway, and is be
reintroduced in future if required (Hugh has a proof of concept).
Once PageReserved() calls are removed from kernel/power/swsusp.c, and all
arch/ and driver code, the Set and Clear calls, and the PG_reserved bit can
be trivially removed.
Last real user of PageReserved is swsusp, which uses PageReserved to
determine whether a struct page points to valid memory or not. This still
needs to be addressed (a generic page_is_ram() should work).
A last caveat: the ZERO_PAGE is now refcounted and managed with rmap (and
thus mapcounted and count towards shared rss). These writes to the struct
page could cause excessive cacheline bouncing on big systems. There are a
number of ways this could be addressed if it is an issue.
