This sets us up to be able to convert the srp_host to use a struct device instead of a class_device. Based on a original patch from Tony Jones, but split up into this piece by Greg. Signed-off-by:

Requiring userspace to close and re-open sysfs attributes has been the policy since before 2.6.12. It allows userspace to get a consistent snapshot of kernel state and consume it with incremental reads and seeks. Now, if the file position is zero the kernel assumes userspace wants to see the new value. The application for this change is to allow a userspace RAID metadata handler to check the state of an array without causing any memory allocations. Thus not causing writeback to a raid array that might be blocked waiting for userspace to take action. Cc: Neil Brown <neilb@suse.de> Acked-by:

After 2.6.24 there was a plan to make the PM core acquire all device semaphores during a suspend/hibernation to protect itself from concurrent operations involving device objects. That proved to be too heavy-handed and we found a better way to achieve the goal, but before it happened, we had introduced the functions device_pm_schedule_removal() and destroy_suspended_device() to allow drivers to "safely" destroy a suspended device and we had adapted some drivers to use them. Now that these functions are no longer necessary, it seems reasonable to remove them and modify their users to use the normal device unregistration instead. Signed-off-by:

Add /sysfs/firmware/ibft/[initiator|targetX|ethernetX] directories along with text properties which export the the iSCSI Boot Firmware Table (iBFT) structure. What is iSCSI Boot Firmware Table? It is a mechanism for the iSCSI tools to extract from the machine NICs the iSCSI connection information so that they can automagically mount the iSCSI share/target. Currently the iSCSI information is hard-coded in the initrd. The /sysfs entries are read-only one-name-and-value fields. The usual set of data exposed is: # for a in `find /sys/firmware/ibft/ -type f -print`; do echo -n "$a: "; cat $a; done /sys/firmware/ibft/target0/target-name: iqn.2007.com.intel-sbx44:storage-10gb /sys/firmware/ibft/target0/nic-assoc: 0 /sys/firmware/ibft/target0/chap-type: 0 /sys/firmware/ibft/target0/lun: 00000000 /sys/firmware/ibft/target0/port: 3260 /sys/firmware/ibft/target0/ip-addr: 192.168.79.116 /sys/firmware/ibft/target0/flags: 3 /sys/firmware/ibft/target0/index: 0 /sys/firmware/ibft/ethernet0/mac: 00:11:25:9d:8b:01 /sys/firmware/ibft/ethernet0/vlan: 0 /sys/firmware/ibft/ethernet0/gateway: 192.168.79.254 /sys/firmware/ibft/ethernet0/origin: 0 /sys/firmware/ibft/ethernet0/subnet-mask: 255.255.252.0 /sys/firmware/ibft/ethernet0/ip-addr: 192.168.77.41 /sys/firmware/ibft/ethernet0/flags: 7 /sys/firmware/ibft/ethernet0/index: 0 /sys/firmware/ibft/initiator/initiator-name: iqn.2007-07.com:konrad.initiator /sys/firmware/ibft/initiator/flags: 3 /sys/firmware/ibft/initiator/index: 0 For full details of the IBFT structure please take a look at: ftp://ftp.software.ibm.com/systems/support/system_x_pdf/ibm_iscsi_boot_firmware_table_v1.02.pdf [akpm@linux-foundation.org: fix build] Signed-off-by:

The various wakeup flags and their accessor macros in struct dev_pm_info should be available whenever CONFIG_PM is enabled, not just when CONFIG_PM_SLEEP is on. Otherwise remote wakeup won't always be configurable for runtime power management. This patch (as1056b) fixes the oversight. David Brownell adds: More accurately, fixes the "regression" ... as noted sometime last summer, after 296699de introduced CONFIG_SUSPEND. But that didn't make the regression list for that kernel, ergo the delay in fixing it. [rjw: rebased] Signed-off-by:

Include dpm_sysfs_add() into device_pm_add(), in analogy with device_pm_remove(), and modify device_add() to call the latter after bus_add_device(), to avoid situations in which the PM core may attempt to suspend a device the registration of which has not been successful. Signed-off-by:
-
Rafael J. Wysocki authored
Modify the PM core to protect its data structures, specifically the dpm_active list, from being corrupted if a child of the currently suspending device is registered concurrently with its ->suspend() callback. In that case, since the new device (the child) is added to dpm_active after its parent, the PM core will attempt to suspend it after the parent, which is wrong. Introduce a new member of struct dev_pm_info, called 'sleeping', and use it to check if the parent of the device being added to dpm_active has been suspended, in which case the device registration fails. Also, use 'sleeping' for checking if the ordering of devices on dpm_active is correct. Introduce variable 'all_sleeping' that will be set to 'true' once all devices have been suspended and make new device registrations fail until 'all_sleeping' is reset to 'false', in order to avoid having unsuspended devices around while the system is going into a sleep state. Remove pm_sleep_rwsem which is not necessary any more. Special thanks to Alan Stern for discussions and suggestions that lead to the creation of this patch. Signed-off-by:

I've just found how easy it is to accidentally register a sysdev_driver for two different classes. When this happens, bad things happen as the sysdev_driver structure keeps has the list entry for the driver registration. The following patch makes a WARN_ON() if this happens, although I think BUG_ON or returning -EAGAIN could also be valid responses to this. Signed-off-by:

The current PNP combined card + devices module aliase can never ever match anything, because these values are not available all at the same time to request a module. Instead of adding the combined alias, we add the device id's all as individual aliases. Device id's are exported by the PNP bus and can now properly used to request the loading of a matching module. The module snd-sbawe currently exports aliases, which can never match anything: alias: pnp:cCTLXXXXdCTL0045dCTL0022* alias: pnp:cCTLXXXXdCTL0044dCTL0023* alias: pnp:cCTLXXXXdCTL0042dCTL0022* alias: pnp:cCTLXXXXdCTL0041dCTL0021* alias: pnp:cCTLXXXXdCTL0031dCTL0021* alias: pnp:cCTL00eddCTL0041dCTL0070* alias: pnp:cCTL00e9dCTL0045dCTL0022* alias: pnp:cCTL00e4dCTL0045dCTL0022* alias: pnp:cCTL00c7dCTL0045dCTL0022* alias: pnp:cCTL00c5dCTL0045dCTL0022* alias: pnp:cCTL00c3dCTL0045dCTL0022* alias: pnp:cCTL00c1dCTL0042dCTL0022* alias: pnp:cCTL00b2dCTL0044dCTL0023* alias: pnp:cCTL009edCTL0044dCTL0023* alias: pnp:cCTL009ddCTL0042dCTL0022* alias: pnp:cCTL009fdCTL0041dCTL0021* alias: pnp:cCTL009cdCTL0041dCTL0021* alias: pnp:cCTL009adCTL0041dCTL0021* alias: pnp:cCTL0054dCTL0031dCTL0021* alias: pnp:cCTL0048dCTL0031dCTL0021* alias: pnp:cCTL0047dCTL0031dCTL0021* alias: pnp:cCTL0046dCTL0031dCTL0021* alias: pnp:cCTL0045dCTL0031dCTL0021* alias: pnp:cCTL0044dCTL0031dCTL0021* alias: pnp:cCTL0043dCTL0031dCTL0021* alias: pnp:cCTL0042dCTL0031dCTL0021* alias: pnp:cCTL0039dCTL0031dCTL0021* alias: pnp:cCTL0035dCTL0031dCTL0021* With this patch it exports only the device id's, as properly matchable aliases: alias: pnp:dCTL0070* alias: pnp:dCTL0045* alias: pnp:dCTL0023* alias: pnp:dCTL0044* alias: pnp:dCTL0022* alias: pnp:dCTL0042* alias: pnp:dCTL0041* alias: pnp:dCTL0021* alias: pnp:dCTL0031* Now, the exported value of the PNP bus can be used to autoload a matching module: $ modprobe --first-time -n -v pnp:dCTL0045 insmod /lib/modules/2.6.24-rc6-g5b825ed2-dirty/kernel/sound/core/snd-rawmidi.ko insmod /lib/modules/2.6.24-rc6-g5b825ed2-dirty/kernel/sound/drivers/mpu401/snd-mpu401-uart.ko insmod /lib/modules/2.6.24-rc6-g5b825ed2-dirty/kernel/sound/core/snd-hwdep.ko insmod /lib/modules/2.6.24-rc6-g5b825ed2-dirty/kernel/sound/isa/sb/snd-sb-common.ko insmod /lib/modules/2.6.24-rc6-g5b825ed2-dirty/kernel/sound/isa/sb/snd-sb16-csp.ko insmod /lib/modules/2.6.24-rc6-g5b825ed2-dirty/kernel/sound/isa/sb/snd-sb16-dsp.ko insmod /lib/modules/2.6.24-rc6-g5b825ed2-dirty/kernel/sound/drivers/opl3/snd-opl3-lib.ko insmod /lib/modules/2.6.24-rc6-g5b825ed2-dirty/kernel/sound/isa/sb/snd-sbawe.ko $ grep CTL0045 /sys/bus/pnp/devices/*/id /sys/bus/pnp/devices/01:01.00/id:CTL0045 Signed-off-by:

driver core: Convert debug functions declared inline __attribute__((format (printf,x,y) to statement expression macros When DEBUG is not defined, pr_debug and dev_dbg and some other local debugging functions are specified as: "inline __attribute__((format (printf, x, y)))" This is done to validate printk arguments when not debugging. Converting these functions to macros or statement expressions "do { if (0) printk(fmt, ##arg); } while (0)" or "({ if (0) printk(fmt, ##arg); 0; }) makes at least gcc 4.2.2 produce smaller objects. This has the additional benefit of allowing the optimizer to avoid calling functions like print_mac that might have been arguments to the printk. defconfig x86 current: $ size vmlinux text data bss dec hex filename 4716770 474560 618496 5809826 58a6a2 vmlinux all converted: (More patches follow) $ size vmlinux text data bss dec hex filename 4716642 474560 618496 5809698 58a622 vmlinux Even kernel/sched.o, which doesn't even use these functions, becomes smaller.

register_memory()/unregister_memory() never gets called with "root". unregister_memory() is accessing kobject_name of the object just freed up. Since no one uses the code, lets take the code out. And also, make register_memory() static. Another bug fix - before calling unregister_memory() remove_memory_block() gets a ref on kobject. unregister_memory() need to drop that ref before calling sysdev_unregister(). Signed-off-by:

This patch implements a UIO interface for the SMX Cryptengine. The Cryptengine found on the Nias Digital SMX board is best suited for a UIO interface. It is not wired in to the cryptographic API as the engine handles it's own keys, algorithms, everything. All that we know about is that if there's room in the buffer, you can write data to it and when there's data ready, you read it out again. There isn't necessarily even any direct correlation between data going in and data coming out again, the engine may consume or generate data all on its own. This driver is for proprietary hardware but we're always told to submit the drivers anyway; here you are. :-) This is version 4 of this patch and addresses all issues raised by Hans-Jürgen Koch and Paul Mundt in their reviews. Slightly altered is Paul's suggestion to use DRV_NAME and DRV_VERSION as the UIO version and name. While at the moment they are the same, there is no reason for them to stay that way. Nevertheless we now at least provide a MODULE_VERSION macro to keep modinfo happy. Signed-off-by:

Add the security= boot parameter. This is done to avoid LSM registration clashes in case of more than one bult-in module. User can choose a security module to enable at boot. If no security= boot parameter is specified, only the first LSM asking for registration will be loaded. An invalid security module name will be treated as if no module has been chosen. LSM modules must check now if they are allowed to register by calling security_module_enable(ops) first. Modify SELinux and SMACK to do so. Do not let SMACK register smackfs if it was not chosen on boot. Smackfs assumes that smack hooks are registered and the initial task security setup (swapper->security) is done. Signed-off-by:
