2010-07-01Merge branch 'linus' into core/rcuIngo Molnar
Conflicts: fs/fs-writeback.c Merge reason: Resolve the conflict Note, i picked the version from Linus's tree, which effectively reverts the fs-writeback.c bits of: b97181f: fs: remove all rcu head initializations, except on_stack initializations As the upstream changes to this file changed this code heavily and the first attempt to resolve the conflict resulted in a non-booting kernel. It's safer to re-try this portion of the commit cleanly. Signed-off-by: Ingo Molnar <mingo@elte.hu>

According to my schematics, on Lite5200 board ethernet phy uses address 0 (all ADDR lines are pulled down). With this change I can talk to onboard phy (LXT971) and correctly use autonegotiation.

2010-06-15powerpc/5200: fix oops during going to standbyDmitry Baryshkov
When going to standby mode mpc code maps the whole soc5200 node to access warious MBAR registers. However as of_iomap uses 'reg' property of device node, only small part of MBAR is getting mapped. Thus pm code gets oops when trying to access high parts of MBAR. As a way to overcome this, make mpc52xx_pm_prepare() explicitly map whole MBAR (0xc0000).

2010-06-15powerpc: rtas_flash needs to use rtas_data_bufMilton Miller
When trying to flash a machine via the update_flash command, Anton received the following error: Restarting system. FLASH: kernel bug...flash list header addr above 4GB The code in question has a comment that the flash list should be in the kernel data and therefore under 4GB: /* NOTE: the "first" block list is a global var with no data * blocks in the kernel data segment. We do this because * we want to ensure this block_list addr is under 4GB. */ Unfortunately the Kconfig option is marked tristate which means the variable may not be in the kernel data and could be above 4GB. Instead of relying on the data segment being below 4GB, use the static data buffer allocated by the kernel for use by rtas. Since we don't use the header struct directly anymore, convert it to a simple pointer.

2010-06-15powerpc/kexec: Wait for online/possible CPUs only.Matt Evans
kexec_perpare_cpus_wait() iterates i through NR_CPUS to check paca[i].kexec_state of each to make sure they have quiesced. However now we have dynamic PACA allocation, paca[NR_CPUS] is not necessarily valid and we overrun the array; spurious "cpu is not possible, ignoring" errors result. This patch iterates for_each_online_cpu so stays within the bounds of paca[] -- and every CPU is now 'possible'.

2010-06-15powerpc: Move kdump default base address to 64MB on 64bitAnton Blanchard
We are seeing boot fails on some System p machines when using the kdump crashkernel= boot option. The default kdump base address is 32MB, so if we reserve 256MB for kdump then we reserve all of the RMO except the first 32MB. We really want kdump to reserve some memory in the RMO and most of it elsewhere but that will require more significant changes. For now we can shift the default base address to 64MB when CONFIG_PPC64 and CONFIG_RELOCATABLE are set. This isn't quite correct since what we really care about is the kdump kernel is relocatable, but we already make the assumption that base kernel and kdump kernel have the same CONFIG_RELOCATABLE setting, eg: #ifndef CONFIG_RELOCATABLE if (crashk_res.start != KDUMP_KERNELBASE) printk("Crash kernel location must be 0x%x\n", KDUMP_KERNELBASE); ... RTAS is instantiated towards the top of our RMO, so if we were to go any higher we risk not having enough RMO memory for the kdump kernel on boxes with a 128MB RMO.

2010-06-11PCI: clear bridge resource range if BIOS assigned bad oneYinghai Lu
Yannick found that video does not work with 2.6.34. The cause of this bug was that the BIOS had assigned the wrong range to the PCI bridge above the video device. Before 2.6.34 the kernel would have shrunk the size of the bridge window, but since d65245c PCI: don't shrink bridge resources the kernel will avoid shrinking BIOS ranges. So zero out the old range if we fail to claim it at boot time; this will cause us to allocate a new range at startup, restoring the 2.6.34 behavior.

Grant patches added an of mach table to struct device_driver. However, while he changed the macio device code to use that, he left the match table pointer in struct macio_driver and didn't update drivers to use the "new" one, thus breaking the probing. This completes the change by moving all drivers to setup the "new" one, removing all traces of the old one, and while at it (since it changes the exact same locations), I also remove two other duplicates from struct driver which are the name and owner fields.

We don't name our generic fsync implementations very well currently.

This patch renames the generic file fsync method to generic_file_fsync to match the other generic_file_* routines it is supposed to be used with, and the no-op implementation to noop_fsync to make it obvious what to expect.

2010-05-25endian: #define __BYTE_ORDERJoakim Tjernlund
Linux does not define __BYTE_ORDER in its endian header files which makes some header files bend backwards to get at the current endian. Lets #define __BYTE_ORDER in big_endian.h/litte_endian.h to make it easier for header files that are used in user space too. In userspace the convention is that 1. _both_ __LITTLE_ENDIAN and __BIG_ENDIAN are defined, 2. you have to test for e.g. __BYTE_ORDER == __BIG_ENDIAN.
