* ibft: fix target info parsing in ibft moduleMike Christie2008-09-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I got this patch through Red Hat's bugzilla from the bug submitter and patch creator. I have just fixed it up so it applies without fuzz to upstream kernels. Original patch and description from Shyam kumar Iyer: The issue [ibft module not displaying targets with short names] is because of an offset calculatation error in the iscsi_ibft.c code. Due to this error directory structure for the target in /sys/firmware/ibft does not get created and so the initiator is unable to connect to the target. Note that this bug surfaced only with an name that had a short section at the end. eg: "iqn.1984-05.com.dell:dell". It did not surface when the iqn's had a longer section at the end. eg: "iqn.2001-04.com.example:storage.disk2.sys1.xyz" So, the eot_offset was calculated such that an extra 48 bytes i.e. the size of the ibft_header which has already been accounted was subtracted twice. This was not evident with longer iqn names because they would overshoot the total ibft length more than 48 bytes and thus would escape the bug.

* cpumask: Replace cpumask_of_cpu with cpumask_of_cpu_ptrMike Travis2008-07-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * This patch replaces the dangerous lvalue version of cpumask_of_cpu with new cpumask_of_cpu_ptr macros. These are patterned after the node_to_cpumask_ptr macros. In general terms, if there is a cpumask_of_cpu_map[] then a pointer to the cpumask_of_cpu_map[cpu] entry is used. The cpumask_of_cpu_map is provided when there is a large NR_CPUS count, reducing greatly the amount of code generated and stack space used for cpumask_of_cpu(). The pointer to the cpumask_t value is needed for calling set_cpus_allowed_ptr() to reduce the amount of stack space needed to pass the cpumask_t value. If there isn't a cpumask_of_cpu_map[], then a temporary variable is declared and filled in with value from cpumask_of_cpu(cpu) as well as a pointer variable pointing to this temporary variable. Afterwards, the pointer is used to reference the cpumask value. The compiler will optimize out the extra dereference through the pointer as well as the stack space used for the pointer, resulting in identical code. A good example of the orthogonal usages is in net/sunrpc/svc.c: case SVC_POOL_PERCPU: { unsigned int cpu = m->pool_to[pidx]; cpumask_of_cpu_ptr(cpumask, cpu); *oldmask = current->cpus_allowed; set_cpus_allowed_ptr(current, cpumask); return 1; } case SVC_POOL_PERNODE: { unsigned int node = m->pool_to[pidx]; node_to_cpumask_ptr(nodecpumask, node); *oldmask = current->cpus_allowed; set_cpus_allowed_ptr(current, nodecpumask); return 1; } Signed-off-by: Mike Travis <travis@sgi.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>

* | sysfs: add /sys/firmware/memmapBernhard Walle2008-07-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds /sys/firmware/memmap interface that represents the BIOS (or Firmware) provided memory map. The tree looks like: /sys/firmware/memmap/0/start (hex number) end (hex number) type (string) ... /1/start end type With the following shell snippet one can print the memory map in the same form the kernel prints itself when booting on x86 (the E820 map). --------- 8< -------------------------- #!/bin/sh cd /sys/firmware/memmap for dir in * ; do start=$(cat $dir/start) end=$(cat $dir/end) type=$(cat $dir/type) printf "%016x-%016x (%s)\n" $start $[ $end +1] "$type" done --------- >8 -------------------------- That patch only provides the needed interface: 1. The sysfs interface. 2. The structure and enumeration definition. 3. The function firmware_map_add() and firmware_map_add_early() that should be called from architecture code (E820/EFI, for example) to add the contents to the interface. If the kernel is compiled without CONFIG_FIRMWARE_MEMMAP, the interface does nothing without cluttering the architecture-specific code with #ifdef's. The purpose of the new interface is kexec: While /proc/iomem represents the *used* memory map (e.g. modified via kernel parameters like 'memmap' and 'mem'), the /sys/firmware/memmap tree represents the unmodified memory map provided via the firmware. So kexec can: - use the original memory map for rebooting, - use the /proc/iomem for setting up the ELF core headers for kdump case that should only represent the memory of the system. The patch has been tested on i386 and x86_64.

* ipmi: change device node ordering to reflect probe orderCarol Hebert2008-04-04
| | | | | | | | | | | | | | | | | | | | | | | | In 2.6.14 a patch was merged which switching the order of the ipmi device naming from in-order-of-discovery over to reverse-order-of-discovery. So on systems with multiple BMC interfaces, the ipmi device names are being created in reverse order relative to how they are discovered on the system (e.g. on an IBM x3950 multinode server with N nodes, the device name for the BMC in the first node is /dev/ipmiN-1 and the device name for the BMC in the last node is /dev/ipmi0, etc.). The problem is caused by the list handling routines chosen in dmi_scan.c. Using list_add() causes the multiple ipmi devices to be added to the device list using a stack-paradigm and so the ipmi driver subsequently pulls them off during initialization in LIFO order. This patch changes the dmi_save_ipmi_device() list handling paradigm to a queue, thereby allowing the ipmi driver to build the ipmi device names in the order in which they are found on the system.

* x86: fix DMI out of memory problemsParag Warudkar2008-01-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | People with HP Desktops (including me) encounter couple of DMI errors during boot - dmi_save_oem_strings_devices: out of memory and dmi_string: out of memory. On some HP desktops the DMI data include OEM strings (type 11) out of which only few are meaningful and most other are empty. DMI code religiously creates copies of these 27 strings (65 bytes each in my case) and goes OOM in dmi_string(). If DMI_MAX_DATA is bumped up a little then it goes and fails in dmi_save_oem_strings while allocating dmi_devices of sizeof(struct dmi_device) corresponding to these strings. On x86_64 since we cannot use alloc_bootmem this early, the code uses a static array of 2048 bytes (DMI_MAX_DATA) for allocating the memory DMI needs. It does not survive the creation of empty strings and devices. Fix this by detecting and not newly allocating empty strings and instead using a one statically defined dmi_empty_string. Also do not create a new struct dmi_device for each empty string - use one statically define dmi_device with .name=dmi_empty_string and add that to the dmi_devices list. On x64 this should stop the OOM with same current size of DMI_MAX_DATA and on x86 this should save a good amount of (27*65 bytes + 27*sizeof(struct dmi_device) bootmem.

* Kobject: change drivers/firmware/efivars.c to use kobject_init_and_addGreg Kroah-Hartman2008-01-24
| | | | | | | | | | Stop using kobject_register, as this way we can control the sending of the uevent properly, after everything is properly initialized. Cc: Matt Domsch <Matt_Domsch@dell.com> Cc: Kay Sievers <kay.sievers@vrfy.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

* firmware: change firmware_kset to firmware_kobjGreg Kroah-Hartman2008-01-24
| | | | | | | | | | | | There is no firmware "subsystem" it's just a directory in /sys that other portions of the kernel want to hook into. So make it a kobject not a kset to help alivate anyone who tries to do some odd kset-like things with this.

* kobject: convert efivars to kobj_attr interfaceGreg Kroah-Hartman2008-01-24
| | | | | | | | | | | This cleans up a lot of code and gets rid of a unneeded macro, and gets us one step closer to deleting the deprecated subsys_attr code.

* efivars: make new_var and del_var binary sysfs filesGreg Kroah-Hartman2008-01-24
| | | | | | | | | | | These files should not be "normal" sysfs files as they really are binary ones. This patch makes them binary files and saves code in doing so.

* kobject: remove struct kobj_type from struct ksetGreg Kroah-Hartman2008-01-24
| | | | | | | | | | | | | | | | | We don't need a "default" ktype for a kset. We should set this explicitly every time for each kset. This change is needed so that we can make ksets dynamic, and cleans up one of the odd, undocumented assumption that the kset/kobject/ktype model has. This patch is based on a lot of help from Kay Sievers.

| | | | | | | | | | | | | | | | | gcc 3.2 has a hard time coping with the code in dmi_id_init(): drivers/built-in.o(.init.text+0x789e): In function `dmi_id_init': : undefined reference to `__you_cannot_kmalloc_that_much' make: *** [.tmp_vmlinux1] Error 1 Moving half of the code to a separate function seems to help. This is a no-op for gcc 4.1 which will successfully inline the code anyway.
