kernel_text_address returns true even for modules which is not wanted in text_poke. Use core_kernel_text instead. This is a regression introduced in e587cadd which caused occasionaly crashes after suspend/resume.

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: NRafael J.

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: NKonrad Rzeszutek <konradr@linux.vnet.ibm.com> Cc: Mike Christie <michaelc@cs.wisc.edu> Cc: Peter Jones <pjones@redhat.com> Cc: James Bottomley <James.Bottomley@HansenPartnership.com> Cc: Ingo Molnar <mingo@elte.hu> Cc: Thomas Gleixner <tglx@linutronix.de> Signed-off-by: NAndrew Morton <akpm@linux-foundation.org> Signed-off-by: NGreg Kroah-Hartman <gregkh@suse.de>

* Here is a simple patch to use an allocated array of cpumasks to represent cpumask_of_cpu() instead of constructing one on the stack. It's based on the Kconfig option "HAVE_CPUMASK_OF_CPU_MAP" which is currently only set for x86_64 SMP. Otherwise the the existing cpumask_of_cpu() is used but has been changed to produce an lvalue so a pointer to it can be used. Cc: H.

This patch puts in the code to retry allocation in case it fails. By its own, it does not make much sense but making the code look like x86_64.
