2008-08-20powerpc: Fix vio_bus_probe oops on probe errorBrian King1-1/+1
When CMO is enabled and booted on a non CMO system and the VIO device's probe function fails, an oops can result since vio_cmo_bus_remove is called when it should not. This fixes it by avoiding the vio_cmo_bus_remove call on platforms that don't implement CMO. cpu 0x0: Vector: 300 (Data Access) at [c00000000e13b3d0] pc: c000000000020d34: .vio_cmo_bus_remove+0xc0/0x1f4 lr: c000000000020ca4: .vio_cmo_bus_remove+0x30/0x1f4 sp: c00000000e13b650 msr: 8000000000009032 dar: 0 dsisr: 40000000 current = 0xc00000000e0566c0 paca = 0xc0000000006f9b80 pid = 2428, comm = modprobe enter ? for help [c00000000e13b6e0] c000000000021d94 .vio_bus_probe+0x2f8/0x33c [c00000000e13b7a0] c00000000029fc88 .driver_probe_device+0x13c/0x200 [c00000000e13b830] c00000000029fdac .__driver_attach+0x60/0xa4 [c00000000e13b8c0] c00000000029f050 .bus_for_each_dev+0x80/0xd8 [c00000000e13b980] c00000000029f9ec .driver_attach+0x28/0x40 [c00000000e13ba00] c00000000029f630 .bus_add_driver+0xd4/0x284 [c00000000e13baa0] c0000000002a01bc .driver_register+0xc4/0x198 [c00000000e13bb50] c00000000002168c .vio_register_driver+0x40/0x5c [c00000000e13bbe0] d0000000003b3f1c .ibmvfc_module_init+0x70/0x109c [ibmvfc] [c00000000e13bc70] c0000000000acf08 .sys_init_module+0x184c/0x1a10 [c00000000e13be30] c000000000008748 syscall_exit+0x0/0x40 Signed-off-by: Brian King <brking@linux.vnet.ibm.com> Signed-off-by: Paul Mackerras <paulus@samba.org>
2008-08-20powerpc/ibmebus: Restore "name" sysfs attribute on ibmebus devicesJoachim Fenkes1-12/+0
Recent of_platform changes made of_bus_type_init() overwrite the bus type's .dev_attrs list, meaning that the "name" attribute that ibmebus devices previously had is no longer present. This is a user-visible regression which breaks the userspace eHCA support, since the eHCA userspace driver relies on the name attribute to check for valid adapters. This fixes it by providing the "name" attribute in the generic OF device code instead. Tested on POWER.

2008-08-19Revert "[CPUFREQ][2/2] preregister support for powernow-k8"Linus Torvalds2-75/+37
This reverts commit 34ae7f35a21694aa5cb8829dc5142c39d73d6ba0, which has been reported to cause a number of problems. During suspend and resume, it apparently causes a crash in a CPU hotplug notifier to happen, although the exact details are sketchy because of the inability to get good traces during the suspend sequence. See buzilla entries http://bugzilla.kernel.org/show_bug.cgi?id=11296 http://bugzilla.kernel.org/show_bug.cgi?id=11339 for more examples and details. [ Mark: "Revert the patch for now.

arch/x86/power/cpu_32.c __save_processor_state calls read_cr4() only a i486 CPU doesn't have the CR4 register. Trying to read it produces an invalid opcode oops during suspend to disk. Use the safe rc4 reading op instead. If the value to be written is zero the write is skipped. arch/x86/power/hibernate_asm_32.S done: swapped the use of %eax and %ecx to use jecxz for the zero test and jump over store to %cr4. restore_image: s/%ecx/%eax/ to be consistent with done: In addition to __save_processor_state, acpi_save_state_mem, efi_call_phys_prelog, and efi_call_phys_epilog had checks added (acpi restore was in assembly and already had a check for non-zero). There were other reads and writes of CR4, but MCE and virtualization shouldn't be executed on a i486 anyway. Signed-off-by: David Fries <david@fries.net> Acked-by: H.

The intent of "flush_tlbs" is to invalidate all TLB entries by doing a TLB invalidate instruction for all pages in the address range 0 to 0x00400000. A loop counter is set up at the high value and decremented by page size. However, the loop is only done once as the sense of the conditional branch at the loop end does not match the setup/decrement.

2008-08-16[ARM] 5196/1: fix inline asm constraints for preloadNicolas Pitre1-2/+2
With gcc 4.3 and later, a pointer that has already been dereferenced is assumed not to be null since it should have caused a segmentation fault otherwise, hence any subsequent test against NULL is optimized away. Current inline asm constraint used in the implementation of prefetch() makes gcc believe that the pointer is dereferenced even though the PLD instruction does not load any data and does not cause a segmentation fault on null pointers, which causes all sorts of interesting results when reaching the end of a linked lists for example. Let's use a better constraint to properly represent the actual usage of the pointer value. Problem reported by Chris Steel.

2008-08-15x86: fix section mismatch warning - spp_getpage()Marcin Slusarz1-1/+5
WARNING: vmlinux.o(.text+0x17a3e): Section mismatch in reference from the function set_pte_vaddr_pud() to the function .init.text:spp_getpage() The function set_pte_vaddr_pud() references the function __init spp_getpage(). This is often because set_pte_vaddr_pud lacks a __init annotation or the annotation of spp_getpage is wrong. spp_getpage is called from __init (__init_extra_mapping) and non __init (set_pte_vaddr_pud) functions, so it can't be __init. Unfortunately it calls alloc_bootmem_pages which is __init, but does it only when bootmem allocator is available (after_bootmem == 0). So annotate it accordingly.

2008-08-15x86: Fix ioremap off by one BUGAndi Kleen1-1/+1
Jean Delvare's machine triggered this BUG acpi_os_map_memory phys ffff0000 size 65535 ------------[ cut here ]------------ kernel BUG at arch/x86/mm/pat.c:233! with ACPI in the backtrace. Adding some debugging output showed that ACPI calls acpi_os_map_memory phys ffff0000 size 65535 And ioremap/PAT does this check in 32bit, so addr+size wraps and the BUG in reserve_memtype() triggers incorrectly. BUG_ON(start >= end); /* end is exclusive */ But reserve_memtype already uses u64: int reserve_memtype(u64 start, u64 end, so the 32bit truncation must happen in the caller. Presumably in ioremap when it passes this information to reserve_memtype(). This patch does this computation in 64bit. http://bugzilla.kernel.org/show_bug.cgi?id=11346 Signed-off-by: Andi Kleen <ak@linux.intel.com>
