2008-10-21[PATCH] end of methods switch: remove the old onesAl Viro1-8/+0
Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
2008-10-21[PATCH] beginning of methods conversionAl Viro2-5/+11
To keep the size of changesets sane we split the switch by drivers; to keep the damn thing bisectable we do the following: 1) rename the affected methods, add ones with correct prototypes, make (few) callers handle both. That's this changeset. 2) for each driver convert to new methods. *ALL* drivers are converted in this series. 3) kill the old (renamed) methods. Note that it _is_ a flagday; all in-tree drivers are converted and by the end of this series no trace of old methods remain. The only reason why we do that this way is to keep the damn thing bisectable and allow per-driver debugging if anything goes wrong. New methods: open(bdev, mode) release(disk, mode) ioctl(bdev, mode, cmd, arg) /* Called without BKL */ compat_ioctl(bdev, mode, cmd, arg) locked_ioctl(bdev, mode, cmd, arg) /* Called with BKL, legacy */ Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

2008-10-20PCI: introduce an pci_ioremap(pdev, barnr) functionArjan van de Ven1-0/+13
A common thing in many PCI drivers is to ioremap() an entire bar. This is a slightly fragile thing right now, needing both an address and a size, and many driver writers do.. various things there. This patch introduces an pci_ioremap() function taking just a PCI device struct and the bar number as arguments, and figures this all out itself, in one place. In addition, we can add various sanity checks to this function (the patch already checks to make sure that the bar in question really is a MEM bar; few to no drivers do that sort of thing). Hopefully with this type of API we get less chance of mistakes in drivers with ioremap() operations.

This patch updates the Intel Ibex Peak (PCH) LPC and SMBus Controller DeviceIDs. The LPC Controller ID is set by Firmware within the range of 0x3b00-3b1f. This range is included in pci_ids.h using min and max values, and irq.c now has code to handle the range (in lieu of 32 additions to a SWITCH statement). The SMBus Controller ID is a fixed-value and will not change.

2008-10-20PCI PM: Introduce function pci_wake_from_d3Rafael J. Wysocki1-0/+1
Many device drivers use the following sequence of statements to enable the device to wake up the system while being in the D3_hot or D3_cold low power state: pci_enable_wake(pdev, PCI_D3hot, 1); pci_enable_wake(pdev, PCI_D3cold, 1); However, the second call is not necessary if the first one succeeds (the ordering of the statements above doesn't matter here) and it may even be harmful, because we are not supposed to enable PME# after the wake-up power has been enabled for the device. To allow drivers to overcome this problem, introduce function pci_wake_from_d3() that will enable the device to wake up the system from any of D3_hot and D3_cold as long as the wake-up from at least one of them is supported.

2008-10-20PCI: remove dynids.use_driver_dataMilton Miller1-1/+0
The driver flag dynids.use_driver_data is almost consistently not set, and causes more problems than it solves. It was initially intended as a flag to indicate whether a driver's usage of driver_data had been carefully inspected and was ready for values from userspace. That audit was never done, so most drivers just get a 0 for driver_data when new IDs are added from userspace via sysfs. So remove the flag, allowing drivers to see the data directly (a followon patch validates the passed driver_data value against what the drivers expect).

2008-10-20x86: sysfs: kill owner field from attributeParag Warudkar1-2/+3
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'. But that proved to be too ambitious for now because new usages kept on turning up in subsystem trees.

2008-10-20byteorder: provide swabb.h generically in asm/byteorder.hHarvey Harrison3-0/+3
This is needed during the transition to the new byteorder headers as the swabb.h functionality will be provided from asm/byteorder.h in the new version. To avoid breakage on arches still using the old implementation, provide swabb.h from asm/byteorder.h as well.

2008-10-20byteorder: use generic C version for value byteswappingHarvey Harrison1-10/+0
This makes the new implementation of the byteorder helpers match the old in how it degraded when an arch-defined version was not available: 1) swab() - look for arch defined - if not, use generic c version 2) swabp() - look for arch-defined - if not, deref pointer and use swab() 3) swabs() - look for arch defined - if not, use swabp Signed-off-by: Harvey Harrison <harvey.harrison@gmail.com> Cc: "David S.

2008-10-20kdump: add is_vmcore_usable() and vmcore_unusable()Simon Horman1-0/+24
The usage of elfcorehdr_addr has changed recently such that being set to ELFCORE_ADDR_MAX is used by is_kdump_kernel() to indicate if the code is executing in a kernel executed as a crash kernel. However, arch/ia64/kernel/setup.c:reserve_elfcorehdr will rest elfcorehdr_addr to ELFCORE_ADDR_MAX on error, which means any subsequent calls to is_kdump_kernel() will return 0, even though they should return 1. Ok, at this point in time there are no subsequent calls, but I think its fair to say that there is ample scope for error or at the very least confusion. This patch add an extra state, ELFCORE_ADDR_ERR, which indicates that elfcorehdr_addr was passed on the command line, and thus execution is taking place in a crashdump kernel, but vmcore can't be used for some reason. This is tested for using is_vmcore_usable() and set using vmcore_unusable(). A subsequent patch makes use of this new code. To summarise, the states that elfcorehdr_addr can now be in are as follows: ELFCORE_ADDR_MAX: not a crashdump kernel ELFCORE_ADDR_ERR: crashdump kernel but vmcore is unusable any other value: crash dump kernel and vmcore is usable Signed-off-by: Simon Horman <horms@verge.net.au> Cc: Vivek Goyal <vgoyal@redhat.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2008-10-20kdump: make elfcorehdr_addr independent of CONFIG_PROC_VMCOREVivek Goyal1-4/+10
o elfcorehdr_addr is used by not only the code under CONFIG_PROC_VMCORE but also by the code which is not inside CONFIG_PROC_VMCORE. For example, is_kdump_kernel() is used by powerpc code to determine if kernel is booting after a panic then use previous kernel's TCE table. So even if CONFIG_PROC_VMCORE is not set in second kernel, one should be able to correctly determine that we are booting after a panic and setup calgary iommu accordingly. o So remove the assumption that elfcorehdr_addr is under CONFIG_PROC_VMCORE. o Move definition of elfcorehdr_addr to arch dependent crash files. (Unfortunately crash dump does not have an arch independent file otherwise that would have been the best place). o kexec.c is not the right place as one can Have CRASH_DUMP enabled in second kernel without KEXEC being enabled. o I don't see sh setup code parsing the command line for elfcorehdr_addr. I am wondering how does vmcore interface work on sh. Anyway, I am atleast defining elfcoredhr_addr so that compilation is not broken on sh.

2008-10-20add CONFIG_CORE_DUMP_DEFAULT_ELF_HEADERSRoland McGrath1-1/+7
This adds a kconfig option to change the /proc/PID/coredump_filter default. Fedora has been carrying a trivial patch to change the hard-wired value for this default, since Fedora 8. The default default can't change safely because there are old GDB versions out there (all before 6.7) that are confused by the core dump files created by the MMF_DUMP_ELF_HEADERS setting.
