* [POWERPC] 83xx: MPC837xRDB's VSC7385 ethernet switch isn't on the MDIO busAnton Vorontsov2008-06-104-23/+5
| | | | | | | | | | | | | MDIO-less PHYs should use CONFIG_FIXED_PHY driver and appropriate fixed-link property in the device tree. If not, ethernet will not work: e0024520:03 not found eth1: Could not attach to PHY IP-Config: Failed to open eth1 Signed-off-by: Anton Vorontsov <avorontsov@ru.mvista.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

* [POWERPC] 8610: Update defconfig for MPC8610 HPCDTimur Tabi2008-06-091-136/+180
| | | | | | | | | | | Update the defconfig for the Freescale MPC8610 HPCD board. Enable module support. Disable support for all NICs except for the on-board ULI526x. Enable support for the Freescale DIU driver. Increase the maximum zone order to 12, so that the DIU driver can allocate physically-contiguous 5MB buffers. Enable SYSV IPC and OSS plugin support, which are needed for some OSS apps. Signed-off-by: Timur Tabi <timur@freescale.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
* [POWERPC] 85xx: MPC8548CDS - Fix size of PCIe IO spaceKumar Gala2008-06-091-2/+2
| | | | | | | | Andrew Klossner pointed out the IO space size was in violation of the alignment requirements for windows on the 85xx. The size should have been 1M (to match u-boot). Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
* [POWERPC] 85xx: MPC85xx MDS - Unconditionally select PHYLIB for board fixupsKumar Gala2008-06-091-0/+1
| | | | | | | | | | | | | | | | The MPC85xx MDS board requires some board level tweaks of the PHYs that either the eTSEC (gianfar) or UCC ethernet controllers are connected to. Its possible to build the phylib as a module, however this breaks the board level fix ups because phy_read and phy_write are not available if we build as a module. So we unconditionally select PHYLIB to ensure its built into the kernel if we are building in MPC85xx MDS support. This was determined to be the easiest soultion even though it prevents the user from removing PHYLIB support if they decide they don't want it. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
* uml: activate_mm: remove the dead PF_BORROWED_MM checkOleg Nesterov2008-06-062-13/+3
| | | | | | | | | | | | | | use_mm() was changed to use switch_mm() instead of activate_mm(), since then nobody calls (and nobody should call) activate_mm() with PF_BORROWED_MM bit set. As Jeff Dike pointed out, we can also remove the "old != new" check, it is always true.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Gabriel C <nix.or.die@googlemail.com> pointed out that when the x86 bitops are updated to operate on unsigned long, the code in sdma_abort_task() will produce warnings: drivers/infiniband/hw/ipath/ipath_sdma.c: In function 'sdma_abort_task': drivers/infiniband/hw/ipath/ipath_sdma.c:267: warning: passing argument 2 of 'constant_test_bit' from incompatible pointer type and so on, because it uses test_bit() to operation on a u64 value (returned by ipath_read_kref64() for a hardware register). Fix up these warnings by converting the test_bit() operations to &ing with appropriate symbolic defines of the bits within the hardware register. This has the benign side-effect of making the code more self-documenting as well. Signed-off-by: Roland Dreier <rolandd@cisco.com>

| * | PCI/x86: fix up PCI stuff so that PCI_GOANY supports OLPCAndres Salomon2008-06-054-10/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously, one would have to specifically choose CONFIG_OLPC and CONFIG_PCI_GOOLPC in order to enable PCI_OLPC. That doesn't really work for distro kernels, so this patch allows one to choose CONFIG_OLPC and CONFIG_PCI_GOANY in order to build in OLPC support in a generic kernel (as requested by Robert Millan). This also moves GOOLPC before GOANY in the menuconfig list. Finally, make pci_access_init return early if we detect OLPC hardware. There's no need to continue probing stuff, and pci_pcbios_init specifically trashes our settings (we didn't run into that before because PCI_GOANY wasn't supported).

The CONFIG_DEBUG_SHIRQ flag is by default 'y' with all Fedora kernels since 2.6.23. The problem was reported as https://bugzilla.redhat.com/show_bug.cgi?id=326411 The issue was hunted down to the snd_emu10k1_create() routine: /* pseudo-code */ snd_emu10k1_create(...) { ... request_irq(... IRQF_SHARED ...) { register the irq handler #ifdef CONFIG_DEBUG_SHIRQ call the irq handler: snd_emu10k1_interrupt() { poll I/O port // <---- !! system hangs ... } #endif } ... snd_emu10k1_cardbus_init(...) { initialize I/O ports } ... } The early access to I/O port in the interrupt handler causes the freeze. Obviously it is necessary to init the I/O ports before accessing them. This patch moves the registration of the irq handler after the initialization of the I/O ports.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | support. Source code out there hard-codes a notion of what the _LINUX_CAPABILITY_VERSION #define means in terms of the semantics of the raw capability system calls capget() and capset(). Its unfortunate, but true. Since the confusing header file has been in a released kernel, there is software that is erroneously using 64-bit capabilities with the semantics of 32-bit compatibilities. These recently compiled programs may suffer corruption of their memory when sys_getcap() overwrites more memory than they are coded to expect, and the raising of added capabilities when using sys_capset(). As such, this patch does a number of things to clean up the situation for all. It 1. forces the _LINUX_CAPABILITY_VERSION define to always retain its legacy value. 2. adopts a new #define strategy for the kernel's internal implementation of the preferred magic. 3. deprecates v2 capability magic in favor of a new (v3) magic number. The functionality of v3 is entirely equivalent to v2, the only difference being that the v2 magic causes the kernel to log a "deprecated" warning so the admin can find applications that may be using v2 inappropriately. [User space code continues to be encouraged to use the libcap API which protects the application from details like this. libcap-2.10 is the first to support v3 capabilities.] Fixes issue reported in https://bugzilla.redhat.com/show_bug.cgi?id=447518.

Since I figure that there will be more people reading this kernel-doc-nano-HOWTO.txt file who are kernel developers focused on the rest of the kernel, than there will be readers of this file who are documentation developers extracting that embedded kernel-doc documentation, I have taken the liberty of making the new section added here: How to format kernel-doc comments the first section of the kernel-doc-nano-HOWTO.txt file. This first section is intended to introduce, motivate and provide basic usage of the kernel-doc mechanism for kernel hackers developing other portions of the kernel.

Unfortunately, the atmel_serial driver looks at the whole BRGR register when trying to detect the baud rate that the port is currently running at, so setting FP to a nonzero value breaks the baud rate detection. I'll sit on the u-boot patch for a while longer, but this is clearly a bug in the atmel_serial driver which should be fixed.

In http://lkml.org/lkml/2008/4/29/575 Tony Luck complained that this message references an ipc namespace address that is useless. I first thought of using an audit_log instead of a printk, as suggested by Serge Hallyn. But unfortunately, we do not have any other information than the namespace address to provide here too. So I chose to move the message and output it only at boot time, removing the reference to the namespace.

Previously, since pm->out was a char *, put_user was only copying 1 byte of every PFN, resulting in the top 7 bytes of each PFN not being copied. By requiring that reads be a multiple of 8 bytes, I can make pm->out and pm->end u64*s instead of char*s, which makes put_user work properly, and also simplifies the logic in add_to_pagemap a bit.

After this you'll see the c foo:bar r c foo:bar w lines in a devices.list file. Another example - consider you added 10 'c foo:bar r' permissions to some cgroup (e.g. by mistake). After this you'll see 10 c foo:bar r lines in a list file. This is weird. This situation also has one more annoying consequence. Having many items in a white list makes permissions checking slower, sine it has to walk a longer list. The proposal is to merge permissions for items, that correspond to the same device.
