lib: use generic pci_iomap on all architectures Many architectures don't want to pull in iomap.c, so they ended up duplicating pci_iomap from that file. That function isn't trivial, and we are going to modify it https://lkml.org/lkml/2011/11/14/183 so the duplication hurts. This reduces the scope of the problem significantly, by moving pci_iomap to a separate file and referencing that from all architectures. * tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mst/vhost: alpha: drop pci_iomap/pci_iounmap from pci-noop.c mn10300: switch to GENERIC_PCI_IOMAP mn10300: add missing __iomap markers frv: switch to GENERIC_PCI_IOMAP tile: switch to GENERIC_PCI_IOMAP tile: don't panic on iomap sparc: switch to GENERIC_PCI_IOMAP sh: switch to GENERIC_PCI_IOMAP powerpc: switch to GENERIC_PCI_IOMAP parisc: switch to GENERIC_PCI_IOMAP mips: switch to GENERIC_PCI_IOMAP microblaze: switch to GENERIC_PCI_IOMAP arm: switch to GENERIC_PCI_IOMAP alpha: switch to GENERIC_PCI_IOMAP lib: add GENERIC_PCI_IOMAP lib: move GENERIC_IOMAP to lib/Kconfig Fix up trivial conflicts due to changes nearby in arch/{m68k,score}/Kconfig

2012-01-06frv/PCI: convert to pci_scan_root_bus() for correct root bus resourcesBjorn Helgaas
Convert from pci_scan_bus() to pci_scan_root_bus() and remove root bus resource fixups. This fixes the problem of "early" and "header" quirks seeing incorrect root bus resources. Note that peer root buses are scanned with pci_scan_bus() (which is now deprecated), so they have the default ioport_resource and iomem_resource resources. This is unchanged from before, but these resources are incorrect, and I don't know how to discover the correct ones.

2012-01-06PCI: frv: use generic pcibios_set_master()Myron Stowe

2012-01-06PCI: Pull PCI 'latency timer' setup up into the coreMyron Stowe
The 'latency timer' of PCI devices, both Type 0 and Type 1, is setup in architecture-specific code [see: 'pcibios_set_master()']. There are two approaches being taken by all the architectures - check if the 'latency timer' is currently set between 16 and 255 and if not bring it within bounds, or, do nothing (and then there is the gratuitously different PA-RISC implementation). There is nothing architecture-specific about PCI's 'latency timer' so this patch pulls its setup functionality up into the PCI core by creating a generic 'pcibios_set_master()' function using the '__weak' attribute which can be used by all architectures as a default which, if necessary, can then be over-ridden by architecture-specific code. No functional change. Signed-off-by: Myron Stowe <myron.stowe@redhat.com> Signed-off-by: Jesse Barnes <jbarnes@virtuousgeek.org>

2011-12-21perf, arch: Rework perf_event_index()Peter Zijlstra
Put the logic to compute the event index into a per pmu method. This is required because the x86 rules are weird and wonderful and don't match the capabilities of the current scheme. AFAIK only powerpc actually has a usable userspace read of the PMCs but I'm not at all sure anybody actually used that. ARM is restored to the default since it currently does not support userspace access at all. And all software events are provided with a method that reports their index as 0 (disabled).

2011-11-09net: add wireless TX status socket optionJohannes Berg
The 802.1X EAPOL handshake hostapd does requires knowing whether the frame was ack'ed by the peer. Currently, we fudge this pretty badly by not even transmitting the frame as a normal data frame but injecting it with radiotap and getting the status out of radiotap monitor as well. This is rather complex, confuses users (mon.wlan0 presence) and doesn't work with all hardware. To get rid of that hack, introduce a real wifi TX status option for data frame transmissions. This works similar to the existing TX timestamping in that it reflects the SKB back to the socket's error queue with a SCM_WIFI_STATUS cmsg that has an int indicating ACK status (0/1). Since it is possible that at some point we will want to have TX timestamping and wifi status in a single errqueue SKB (there's little point in not doing that), redefine SO_EE_ORIGIN_TIMESTAMPING to SO_EE_ORIGIN_TXSTATUS which can collect more than just the timestamp; keep the old constant as an alias of course. Currently the internal APIs don't make that possible, but it wouldn't be hard to split them up in a way that makes it possible. Thanks to Neil Horman for helping me figure out the functions that add the control messages. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: John W.

2011-08-03Add Kconfig option ARCH_HAVE_NMI_SAFE_CMPXCHGHuang Ying
cmpxchg() is widely used by lockless code, including NMI-safe lockless code. But on some architectures, the cmpxchg() implementation is not NMI-safe, on these architectures the lockless code may need a spin_trylock_irqsave() based implementation. This patch adds a Kconfig option: ARCH_HAVE_NMI_SAFE_CMPXCHG, so that NMI-safe lockless code can depend on it or provide different implementation according to it. On many architectures, cmpxchg is only NMI-safe for several specific operand sizes. So, ARCH_HAVE_NMI_SAFE_CMPXCHG define in this patch only guarantees cmpxchg is NMI-safe for sizeof(unsigned long).

After changing all consumers of atomics to include <linux/atomic.h>, we ran into some compile time errors due to this dependency chain: linux/atomic.h -> asm/atomic.h -> asm-generic/atomic-long.h where atomic-long.h could use funcs defined later in linux/atomic.h without a prototype. This patches moves the code that includes asm-generic/atomic*.h to linux/atomic.h.

2011-05-28ns: Wire up the setns system callEric W. Biederman
32bit and 64bit on x86 are tested and working. The rest I have looked at closely and I can't find any problems. setns is an easy system call to wire up. It just takes two ints so I don't expect any weird architecture porting problems. While doing this I have noticed that we have some architectures that are very slow to get new system calls. cris seems to be the slowest where the last system calls wired up were preadv and pwritev. avr32 is weird in that recvmmsg was wired up but never declared in unistd.h. frv is behind with perf_event_open being the last syscall wired up. On h8300 the last system call wired up was epoll_wait. On m32r the last system call wired up was fallocate. mn10300 has recvmmsg as the last system call wired up. The rest seem to at least have syncfs wired up which was new in the 2.6.39. v2: Most of the architecture support added by Daniel Lezcano <dlezcano@fr.ibm.com> v3: ported to v2.6.36-rc4 by: Eric W.

2011-03-29frv: Remove stale irq_chip.endThomas Gleixner
irq_chip.end got obsolete with the removal of __do_IRQ(). irq-mb93093.c even lacks an implementation, but nobody noticed that it's broken since commit 88d6e1 in 2006. Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Signed-off-by: David Howells <dhowells@redhat.com>
2011-03-29FRV: Do some cleanupsAmerigo Wang
1. frv doesn't support SMP, remove the useless SMP bits. 2. frv has its own alloc_task_struct, so define __HAVE_ARCH_TASK_STRUCT_ALLOCATOR (I am not sure if frv should use generic alloc_task_struct().) Signed-off-by: WANG Cong <amwang@redhat.com> Signed-off-by: David Howells <dhowells@redhat.com>
2011-03-29FRV: Missing node arg in alloc_thread_info_node() macroDavid Howells
There are two alloc_thread_info_node() macros defined (one for debugging and one for normal). The commit that changed them most recently: commit b6a84016bd2598e35ead635147fa53619982648d Author: Eric Dumazet <eric.dumazet@gmail.com> Date: Tue Mar 22 16:30:42 2011 -0700 Subject: mm: NUMA aware alloc_thread_info_node() didn't add the node argument into the macro argument list for the normal macro. This results in the following error: kernel/fork.c:267:39: error: macro "alloc_thread_info_node" passed 2 arguments, but takes just 1 kernel/fork.c: In function 'dup_task_struct': kernel/fork.c:267: error: 'alloc_thread_info_node' undeclared (first use in this function) kernel/fork.c:267: error: (Each undeclared identifier is reported only once kernel/fork.c:267: error: for each function it appears in.)

2011-03-24percpu: Always align percpu output section to PAGE_SIZETejun Heo
Percpu allocator honors alignment request upto PAGE_SIZE and both the percpu addresses in the percpu address space and the translated kernel addresses should be aligned accordingly. The calculation of the former depends on the alignment of percpu output section in the kernel image. The linker script macros PERCPU_VADDR() and PERCPU() are used to define this output section and the latter takes @align parameter. Several architectures are using @align smaller than PAGE_SIZE breaking percpu memory alignment. This patch removes @align parameter from PERCPU(), renames it to PERCPU_SECTION() and makes it always align to PAGE_SIZE. While at it, add PCPU_SETUP_BUG_ON() checks such that alignment problems are reliably detected and remove percpu alignment comment recently added in workqueue.c as the condition would trigger BUG way before reaching there. For um, this patch raises the alignment of percpu area. As the area is in .init, there shouldn't be any noticeable difference. This problem was discovered by David Howells while debugging boot failure on mn10300.
