i386: Put allocated ELF notes in read-only data segment

2007-07-19T17:04:47Z

This changes the i386 linker script and the asm-generic macro it uses so that ELF note sections with SHF_ALLOC set are linked into the kernel image along with other read-only data. The PT_NOTE also points to their location. This paves the way for putting useful build-time information into ELF notes that can be found easily later in a kernel memory dump.

define new percpu interface for shared data

2007-07-19T17:04:44Z

per cpu data section contains two types of data. One set which is exclusively accessed by the local cpu and the other set which is per cpu, but also shared by remote cpus. In the current kernel, these two sets are not clearely separated out. This can potentially cause the same data cacheline shared between the two sets of data, which will result in unnecessary bouncing of the cacheline between cpus. One way to fix the problem is to cacheline align the remotely accessed per cpu data, both at the beginning and at the end. Because of the padding at both ends, this will likely cause some memory wastage and also the interface to achieve this is not clean. This patch: Moves the remotely accessed per cpu data (which is currently marked as ____cacheline_aligned_in_smp) into a different section, where all the data elements are cacheline aligned. And as such, this differentiates the local only data and remotely accessed data cleanly.

sparc64: fix alignment bug in linker definition script

2007-05-29T19:29:00Z

The RO_DATA section were hardcoded to a specific alignment in include/asm-generic/vmlinux.h. But for sparc64 this did not match the PAGE_SIZE. Introduce a new section definition named: RO_DATA that takes actual alignment as parameter. RODATA are provided for backward compatibility. On top of this avoid hardcoding alignment for sparc64 in reset of the script Fix is build-tested on sparc64 + x86_64. Signed-off-by: Sam Ravnborg

kbuild: introduce __init_refok/__initdata_refok to supress section mismatch warnings

2007-05-19T07:11:58Z

Throughout the kernel there are a few legitimite references to init or exit sections. Most of these are covered by the patterns included in modpost but a few nees special attention. To avoid hardcoding a lot of function names in modpost introduce a marker so relevant function/data can be marked. When modpost see a reference to a init/exit function from a function/data marked no warning will be issued. Idea from: Andrew Morton Signed-off-by: Sam Ravnborg Cc: Andrew Morton

[PATCH] i386: Clean up ELF note generation

2007-05-02T17:27:17Z

Three cleanups: 1: ELF notes are never mapped, so there's no need to have any access flags in their phdr. 2: When generating them from asm, tell the assembler to use a SHT_NOTE section type. There doesn't seem to be a way to do this from C. 3: Use ANSI rather than traditional cpp behaviour to stringify the macro argument.

PCI: Fix multiple problems with VIA hardware

2006-12-20T18:54:43Z

This patch is designed to fix: - Disk eating corruptor on KT7 after resume from RAM - VIA IRQ handling - VIA fixups for bus lockups after resume from RAM The core of this is to add a table of resume fixups run at resume time. We need to do this for a variety of boards and features, but particularly we need to do this to get various critical VIA fixups done on resume. The second part of the problem is to handle VIA IRQ number rules which are a bit odd and need special handling for PIC interrupts. Various patches broke various boxes and while this one may not be perfect (hopefully it is) it ensures the workaround is applied to the right devices only. From: Jean Delvare Now that PCI quirks are replayed on software resume, we can safely re-enable the Asus SMBus unhiding quirk even when software suspend support is enabled.

Remove stack unwinder for now

2006-12-15T16:47:51Z

It has caused more problems than it ever really solved, and is apparently not getting cleaned up and fixed. We can put it back when it's stable and isn't likely to make warning or bug events worse. In the meantime, enable frame pointers for more readable stack traces. Signed-off-by: Linus Torvalds

Make sure we populate the initroot filesystem late enough

2006-12-11T20:12:04Z

We should not initialize rootfs before all the core initializers have run. So do it as a separate stage just before starting the regular driver initializers. Signed-off-by: Linus Torvalds
