Fix almost all coding style issues except for the multi-line macro errors, which do not really apply since the macros are not multi-line statements but declarations.

2012-01-16hwmon: (max1111) Change sysfs interface to in[0-3]_input in millivoltsEric Miao
This patch fixed the inconsistent max1111 sysfs interface as pointed out by Jean Delvare: It was pointed to me that the max1111 driver doesn't implement the standard sysfs interface for hwmon drivers (as described in Documentation/hwmon/sysfs-interface). It exports files adc[0-3]_in, which aren't part of the standard interface. Presumably these should be renamed to in[0-3]_input. Renaming them is probably not sufficient though, as I see no scaling done in the driver. As the MAX1111 chip has a documented full scale of 2.048V, I take it that the LSB of the ADC has a weight of 8 mV. Exporting raw register values to user-space is not OK.

2012-01-16random: Adjust the number of loops when initializingH. Peter Anvin
When we are initializing using arch_get_random_long() we only need to loop enough times to touch all the bytes in the buffer; using poolwords for that does twice the number of operations necessary on a 64-bit machine, since in the random number generator code "word" means 32 bits.

2012-01-16random: Use arch-specific RNG to initialize the entropy storeTheodore Ts'o
If there is an architecture-specific random number generator (such as RDRAND for Intel architectures), use it to initialize /dev/random's entropy stores. Even in the worst case, if RDRAND is something like AES(NSA_KEY, counter++), it won't hurt, and it will definitely help against any other adversaries.

2012-01-14dm: do not forward ioctls from logical volumes to the underlying devicePaolo Bonzini

2012-01-14block: fail SCSI passthrough ioctls on partition devicesPaolo Bonzini
Linux allows executing the SG_IO ioctl on a partition or LVM volume, and will pass the command to the underlying block device. This is well-known, but it is also a large security problem when (via Unix permissions, ACLs, SELinux or a combination thereof) a program or user needs to be granted access only to part of the disk. This patch lets partitions forward a small set of harmless ioctls; others are logged with printk so that we can see which ioctls are actually sent. In my tests only CDROM_GET_CAPABILITY actually occurred. Of course it was being sent to a (partition on a) hard disk, so it would have failed with ENOTTY and the patch isn't changing anything in practice. Still, I'm treating it specially to avoid spamming the logs. In principle, this restriction should include programs running with CAP_SYS_RAWIO. If for example I let a program access /dev/sda2 and /dev/sdb, it still should not be able to read/write outside the boundaries of /dev/sda2 independent of the capabilities. However, for now programs with CAP_SYS_RAWIO will still be allowed to send the ioctls. Their actions will still be logged. This patch does not affect the non-libata IDE driver. That driver however already tests for bd != bd->bd_contains before issuing some ioctl; it could be restricted further to forbid these ioctls even for programs running with CAP_SYS_ADMIN/CAP_SYS_RAWIO.

2012-01-14PM / Domains: Skip governor functions for CONFIG_PM_RUNTIME unsetRafael J. Wysocki
The governor functions in drivers/base/power/domain_governor.c are only used if CONFIG_PM_RUNTIME is set and they refer to data structures that are only present in that case. For this reason, they shouldn't be compiled at all when CONFIG_PM_RUNTIME is not set. Reported-by: Kukjin Kim <kgene.kim@samsung.com> Signed-off-by: Rafael J. Wysocki <rjw@sisk.pl>
2012-01-14PM / Domains: Fix build for CONFIG_PM_SLEEP unsetRafael J. Wysocki
Some callback functions defined in drivers/base/power/domain.c are only necessary if CONFIG_PM_SLEEP is set and they call some other functions that are only available in that case. For this reason, they should not be compiled at all when CONFIG_PM_SLEEP is not set. Reported-by: Magnus Damm <damm@opensource.se> Signed-off-by: Rafael J. Wysocki <rjw@sisk.pl>

2012-01-13nouveau: Support Optimus models for vga_switcherooPeter Lekensteyn
Newer nVidia cards with Optimus do not support/use the DSM switching functions. Instead, it require a DSM function to be called prior to bringing a device into D3 state. No other _DSM calls are necessary before/after enabling/disabling a device. Switching between discrete and integrated GPU is not supported by this Optimus _DSM call, therefore return on the switching method.

2012-01-13nouveau: properly check for _DSM function supportPeter Lekensteyn
According to the ACPI spec version 4, section 9.14.1, _DSM functions must return a value with the first bit enabled if any DSM functions are supported for the given UUID and revision ID. For a given function index n to be marked supported, bit n must be enabled. Signed-off-by: Peter Lekensteyn <lekensteyn@gmail.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
