2008-08-20x86, SGI UV: hardcode the TLB flush interrupt system vectorCliff Wickman
The UV TLB shootdown mechanism needs a system interrupt vector. Its vector had been hardcoded as 200, but needs to moved to the reserved system vector range so that it does not collide with some device vector. This is still temporary until dynamic system IRQ allocation is provided. But it will be needed when real UV hardware becomes available and runs 2.6.27.

2008-08-20powerpc/ibmebus: Restore "name" sysfs attribute on ibmebus devicesJoachim Fenkes
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.

2008-08-18x86: fix build warnings in real mode codeAndi Kleen
This recent patch commit c3965bd15118742d72b4bc1a290d37b3f081eb98 Author: Paul Jackson <pj@sgi.com> Date: Wed May 14 08:15:34 2008 -0700 x86 boot: proper use of ARRAY_SIZE instead of repeated E820MAX constant caused these new warnings during a normal build: In file included from linux-2.6/arch/x86/boot/memory.c:17: linux-2.6/include/linux/log2.h: In function '__ilog2_u32': linux-2.6/include/linux/log2.h:34: warning: implicit declaration of function 'fls' linux-2.6/include/linux/log2.h: In function '__ilog2_u64': linux-2.6/include/linux/log2.h:42: warning: implicit declaration of function 'fls64' linux-2.6/include/linux/log2.h: In function '__roundup_pow_of_two ': linux-2.6/include/linux/log2.h:63: warning: implicit declaration of function 'fls_long' I tried to fix them in log2.h, but it's difficult because the real mode environment is completely different from a normal kernel environment. Instead define an own ARRAY_SIZE macro in boot.h, similar to the other private macros there. Signed-off-by: Andi Kleen <ak@linux.intel.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2008-08-18x86, calgary: fix section mismatch warning - get_tce_space_from_tarMarcin Slusarz
WARNING: vmlinux.o(.text+0x27032): Section mismatch in reference from the function get_tce_space_from_tar() to the function .init.text:calgary_bus_has_devices() The function get_tce_space_from_tar() references the function __init calgary_bus_has_devices(). This is often because get_tce_space_from_tar lacks a __init annotation or the annotation of calgary_bus_has_devices is wrong. get_tce_space_from_tar is called only from __init function (calgary_init) and calls __init function (calgary_bus_has_devices). So annotate it properly. Signed-off-by: Marcin Slusarz <marcin.slusarz@gmail.com> Cc: Chandru Siddalingappa <chandru@in.ibm.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2008-08-18x86: silence section mismatch warning - get_local_pdaMarcin Slusarz
Take out part of get_local_pda referencing __init function (free_bootmem) to new (static) function marked as __ref. It's safe to do because free_bootmem is called before __init sections are dropped. WARNING: vmlinux.o(.cpuinit.text+0x3cd7): Section mismatch in reference from the function get_local_pda() to the function .init.text:free_bootmem() The function __cpuinit get_local_pda() references a function __init free_bootmem(). If free_bootmem is only used by get_local_pda then annotate free_bootmem with a matching annotation.

2008-08-18x86: fix i486 suspend to disk CR4 oopsDavid Fries
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.
