2011-07-22x86/PCI: Preserve existing pci=bfsort whitelist for Dell systemsNarendra_K@Dell.com
Commit 6e8af08dfa40b747002207d3ce8e8b43a050d99f enables pci=bfsort on future Dell systems. But the identification string 'Dell System' matches on already existing whitelist, which do not have SMBIOS type 0xB1, causing pci=bfsort not being set on existing whitelist. This patch fixes the regression by moving the type 0xB1 check beyond the existing whitelist so that existing whitelist is walked before.

2011-07-22PCI: Make the struct pci_dev * argument of pci_fixup_irqs const.Ralf Baechle
Aside of the usual motivation for constification, this function has a history of being abused a hook for interrupt and other fixups so I turned this function const ages ago in the MIPS code but it should be done treewide. Due to function pointer passing in varous places a few other functions had to be constified as well.

2011-07-22x86/PCI: config space accessor functions should not ignore the segment argumentJan Beulich
Without this change, the majority of the raw PCI config space access functions silently ignore a non-zero segment argument, which is certainly wrong. Apart from pci_direct_conf1, all other non-MMCFG access methods get used only for non-extended accesses (i.e. assigned to raw_pci_ops only). Consequently, with the way raw_pci_{read,write}() work, it would be a coding error to call these functions with a non-zero segment (with the current call flow this cannot happen afaict). The access method 1 accessor, as it can be used for extended accesses (on AMD systems) instead gets checks added for the passed in segment to be zero. This would be the case when on such a system having multiple PCI segments (don't know whether any exist in practice) MMCFG for some reason is not usable, and method 1 gets selected for doing extended accesses. Rather than accessing the wrong device's config space, the function will now error out. v2: Convert BUG_ON() to WARN_ON(), and extend description as per Ingo's request.

2011-07-22x86/PCI: reduce severity of host bridge window conflict warningsBjorn Helgaas
Host bridge windows are top-level resources, so if we find a host bridge window conflict, it's probably with a hard-coded legacy reservation. Moving host bridge windows is theoretically possible, but we don't support it; we just ignore windows with conflicts, and it's not worth making this a user-visible error.

2011-07-22x86/PCI: select direct access mode for mmconfig optionShaohua Li
Direct access is needed in mmconf mode too. There are two reasons: 1. we need it to access first 256 bytes. We have bug before that using mmconf to access pci config space hangs system (when resizing BARs), so we use type1 config for legacy config space. 2. when doing mmconfg bar checking, we need access ACPI _CRS, which might access PCI config space.

The recently modified nand buswitth configuration is not aligned with board reality: the double footprint on boards is always populated with 8bits buswidth nand flashes. So we have to consider that without particular configuration the 8bits buswidth is selected by default. Moreover, the previous logic was always using !board_have_nand_8bit(), we change it to a simpler: board_have_nand_16bit().

2011-06-30xen/pci: Use the INT_SRC_OVR IRQ (instead of GSI) to preset the ACPI SCI IRQ.Konrad Rzeszutek Wilk
In the past we would use the GSI value to preset the ACPI SCI IRQ which worked great as GSI == IRQ: ACPI: INT_SRC_OVR (bus 0 bus_irq 9 global_irq 9 low level) While that is most often seen, there are some oddities: ACPI: INT_SRC_OVR (bus 0 bus_irq 9 global_irq 20 low level) which means that GSI 20 (or pin 20) is to be overriden for IRQ 9. Our code that presets the interrupt for ACPI SCI however would use the GSI 20 instead of IRQ 9 ending up with: xen: sci override: global_irq=20 trigger=0 polarity=1 xen: registering gsi 20 triggering 0 polarity 1 xen: --> pirq=20 -> irq=20 xen: acpi sci 20 .. snip.. calling acpi_init+0x0/0xbc @ 1 ACPI: SCI (IRQ9) allocation failed ACPI Exception: AE_NOT_ACQUIRED, Unable to install System Control Interrupt handler (20110413/evevent-119) ACPI: Unable to start the ACPI Interpreter as the ACPI interpreter made a call to 'acpi_gsi_to_irq' which got nine. It used that value to request an IRQ (request_irq) and since that was not present it failed. The fix is to recognize that for interrupts that are overriden (in our case we only care about the ACPI SCI) we should use the IRQ number to present the IRQ instead of the using GSI. End result is that we get: xen: sci override: global_irq=20 trigger=0 polarity=1 xen: registering gsi 20 triggering 0 polarity 1 xen: --> pirq=20 -> irq=9 (gsi=9) xen: acpi sci 9 which fixes the ACPI interpreter failing on startup.

2011-06-27Fix node_start/end_pfn() definition for mm/page_cgroup.cKAMEZAWA Hiroyuki
commit 21a3c96 uses node_start/end_pfn(nid) for detection start/end of nodes. But, it's not defined in linux/mmzone.h but defined in /arch/???/include/mmzone.h which is included only under CONFIG_NEED_MULTIPLE_NODES=y. Then, we see mm/page_cgroup.c: In function 'page_cgroup_init': mm/page_cgroup.c:308: error: implicit declaration of function 'node_start_pfn' mm/page_cgroup.c:309: error: implicit declaration of function 'node_end_pfn' So, fixiing page_cgroup.c is an idea... But node_start_pfn()/node_end_pfn() is a very generic macro and should be implemented in the same manner for all archs. (m32r has different implementation...) This patch removes definitions of node_start/end_pfn() in each archs and defines a unified one in linux/mmzone.h. It's not under CONFIG_NEED_MULTIPLE_NODES, now. A result of macro expansion is here (mm/page_cgroup.c) for !NUMA start_pfn = ((&contig_page_data)->node_start_pfn); end_pfn = ({ pg_data_t *__pgdat = (&contig_page_data); __pgdat->node_start_pfn + __pgdat->node_spanned_pages;}); for NUMA (x86-64) start_pfn = ((node_data[nid])->node_start_pfn); end_pfn = ({ pg_data_t *__pgdat = (node_data[nid]); __pgdat->node_start_pfn + __pgdat->node_spanned_pages;}); Changelog: - fixed to avoid using "nid" twice in node_end_pfn() macro.

2011-06-22powerpc/e500: fix breakage with fsl_rio_mcheck_exceptionScott Wood
The wrong MCSR bit was being used on e500mc. MCSR_BUS_RBERR only exists on e500v1/v2. Use MCSR_LD on e500mc, and remove all MCSR checking in fsl_rio_mcheck_exception as we now no longer call that function if the appropriate bit in MCSR is not set. If RIO support was enabled at compile-time, but was never probed, just return from fsl_rio_mcheck_exception rather than dereference a NULL pointer. TODO: There is still a remaining, though comparitively minor, issue in that this recovery mechanism will falsely engage if there's an unrelated MCSR_LD event at the same time as a RIO error.

2011-06-22powerpc/p1022ds: fix audio-related properties in the device treeTimur Tabi
On the Freescale P1022DS reference board, the SSI audio controller is connected in "asynchronous" mode to the codec's clocks, so the device tree needs an "fsl,ssi-asynchronous" property. Also remove the clock-frequency property from the wm8776 node, because the clock is enabled only if U-Boot enables it, and U-Boot will set the property if the clock is enabled. A future version of the P1022DS audio driver will configure the clock itself, but for now, the driver should not be told that the clock is running when it isn't. Also fix the FIFO depth to 15, instead of 16. Signed-off-by: Timur Tabi <timur@freescale.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
2011-06-21MN10300: asm/uaccess.h needs to #include linux/kernel.h for might_sleep()David Howells
MN10300's asm/uaccess.h needs to #include linux/kernel.h to get might_sleep() otherwise it fails to build on MN10300 allyesconfig. This fails in a few places with messages like the following: In file included from security/keys/trusted.c:14: include/linux/uaccess.h: In function '__copy_from_user_nocache': include/linux/uaccess.h:52: error: implicit declaration of function 'might_sleep' Signed-off-by: David Howells <dhowells@redhat.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2011-06-21ARM: 6961/1: zImage: Add build-time check for correctly-sized proc_type entriesDave Martin
It is easy to mis-maintain the proc_types table such that the entries become wrongly-sized and misaligned when the kernel is built in Thumb-2. This patch adds an assembly-time check which will turn most common size/alignment mistakes in this table into build failures, to avoid having to debug the boot-time kernel hang which would happen if the resulting kernel were actually booted.

When we bring a CPU online, we should wait for it to become active before entering the idle thread, so we know that the scheduler and thread migration is going to work. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
