2009-10-05iSCSI/iBFT: use proper address translationJan Beulich
In virtual environments (namely, Xen Dom0) virt <-> phys and virt <-> isa-bus translations cannot be freely interchanged (and even outside such environments it is not really correct to do so). When looking at memory below 1M, the latter translations should always be used. iscsi_ibft_find.c part from: Martin Wilck <martin.wilck@ts.fujitsu.com>.

2009-09-22mm: don't use alloc_bootmem_low() where not strictly neededJan Beulich
Since alloc_bootmem() will never return inaccessible (via virtual addressing) memory anyway, using the ..._low() variant only makes sense when the physical address range of the allocated memory must fulfill further constraints, espacially since on 64-bits (or more generally in all cases where the pools the two variants allocate from are than the full available range. Probably the use in alloc_tce_table() could also be eliminated (based on code inspection of pci-calgary_64.c), but that seems too risky given I know nothing about that hardware and have no way to test it.

2009-09-08dmi: extend dmi_get_year() to dmi_get_date()Tejun Heo
There are cases where full date information is required instead of just the year. Add month and day parsing to dmi_get_year() and rename it to dmi_get_date(). As the original function only required '/' followed by any number of parseable characters at the end of the string, keep that behavior to avoid upsetting existing users. The new function takes dates of format [mm[/dd]]/yy[yy]. Year, month and date are checked to be in the ranges of [1-9999], [1-12] and [1-31] respectively and any invalid or out-of-range component is returned as zero. The dummy implementation is updated accordingly but the return value is updated to indicate field not found which is consistent with how other dummy functions behave.

2009-09-08dmi: fix date handling in dmi_get_year()Tejun Heo
Year parsing in dmi_get_year() had the following two bugs. * "00" is treated as invalid instead of 2000 because zero return from simple_strtoul() is treated as error. * "0N" where N >= 8 is treated as invalid of 200N because the leading 0 is considered to specify octal. Fix the above two bugs by using endptr to detect invalid number and forcing decimal. Signed-off-by: Tejun Heo <tj@kernel.org> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>

2009-06-17[IA64] Convert ia64 to use int-ll64.hMatthew Wilcox
It is generally agreed that it would be beneficial for u64 to be an unsigned long long on all architectures. ia64 (in common with several other 64-bit architectures) currently uses unsigned long. Migrating piecemeal is too painful; this giant patch fixes all compilation warnings and errors that come as a result of switching to use int-ll64.h. Note that userspace will still see __u64 defined as unsigned long. This is important as it affects C++ name mangling.

2009-06-10[libata] ahci: Restore SB600 SATA controller 64 bit DMAShane Huang
Community reported one SB600 SATA issue(BZ #9412), which led to 64 bit DMA disablement for all SB600 revisions by driver maintainers with commits c7a42156d99bcea7f8173ba7a6034bbaa2ecb77c and 4cde32fc4b32e96a99063af3183acdfd54c563f0. But the root cause is ASUS M2A-VM system BIOS bug in old revisions like 0901, while forcing into 32bit DMA happens to work as workaround. Now it's time to withdraw 4cde32fc4b32e96a99063af3183acdfd54c563f0 so as to restore the SB600 SATA 64bit DMA capability. This patch is also adding the workaround for M2A-VM old BIOS revisions, but users are suggested to upgrade their system BIOS to the latest one if they meet this issue.

Fix the display of a few fields in the iBFT NIC attribute structure in sysfs. Ensure that, if the DHCP IP address and the subnet mask for the interface is present in the iBFT NIC structure, the corresponding entries are created in sysfs tree for the device. This would hence create the additional entries in the tree based on the iBFT table and would not delete any existing entries.

2009-01-27DMI: Introduce dmi_first_match to make the interface more flexibleRafael J. Wysocki
Some notebooks from HP have the problem that their BIOSes attempt to spin down hard drives before entering ACPI system states S4 and S5. This leads to a yo-yo effect during system power-off shutdown and the last phase of hibernation when the disk is first spun down by the kernel and then almost immediately turned on and off by the BIOS. This, in turn, may result in shortening the disk's life times. To prevent this from happening we can blacklist the affected systems using DMI information. However, only the on-board controlles should be blacklisted and their PCI slot numbers can be used for this purpose. Unfortunately the existing interface for checking DMI information of the system is not very convenient for this purpose, because to use it, we would have to define special callback functions or create a separate struct dmi_system_id table for each blacklisted system. To overcome this difficulty introduce a new function dmi_first_match() returning a pointer to the first entry in an array of struct dmi_system_id elements that matches the system DMI information. Then, we can use this pointer to access the entry's .driver_data field containing the additional information, such as the PCI slot number, allowing us to do the desired blacklisting.

Impact: Should permit VMware detection on older platforms where the vendor is changed.

Tejun's commit 7b595756ec1f49e0049a9e01a1298d53a7faaa15 made sysfs attribute->owner unnecessary. But the field was left in the structure to ease the merge. It's been over a year since that change and it is now time to start killing attribute->owner along with its users - one arch at a time! This patch is attempt #1 to get rid of attribute->owner only for CONFIG_X86_64 or CONFIG_X86_32 . We will deal with other arches later on as and when possible - avr32 will be the next since that is something I can test. Compile (make allyesconfig / make allmodconfig / custom config) and boot tested. akpm: the idea is that we put the declaration of sttribute.owner inside `#ifndef CONFIG_X86'.

2008-09-02ibft: fix target info parsing in ibft moduleMike Christie
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.

2008-07-18cpumask: Replace cpumask_of_cpu with cpumask_of_cpu_ptrMike Travis
* 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>
