avr32: remove support for AVR32 architecture

2017-05-01T07:27:15+00:00

This patch drops support for AVR32 architecture from the Linux kernel. The AVR32 architecture is not keeping up with the development of the kernel, and since it shares so much of the drivers with Atmel ARM SoC, it is starting to hinder these drivers to develop swiftly. Also, all AVR32 AP7 SoC processors are end of lifed from Atmel (now Microchip). Finally, the GCC toolchain is stuck at version 4.2.x, and has not received any patches since the last release from Atmel; 4.2.4-atmel.1.1.3.avr32linux.1. When building kernel v4.10, this toolchain is no longer able to properly link the network stack. Haavard and I have came to the conclusion that we feel keeping AVR32 on life support offers more obstacles for Atmel ARMs, than it gives joy to AVR32 users. I also suspect there are very few AVR32 users left today, if anybody at all.

oprofilefs_create_...() do not need superblock argument

same story as with oprofilefs_mkdir() Signed-off-by: Al Viro

oprofilefs_mkdir() doesn't need superblock argument

2013-09-04T02:52:47+00:00

it's always equal to ->d_sb of the second argument (parent dentry), due to either being literally that, or ->d_sb of parent's parent. Signed-off-by: Al Viro

Disintegrate asm/system.h for AVR32

Disintegrate asm/system.h for AVR32. This has not been compiled at all. Signed-off-by: David Howells cc: Haavard Skinnemoen

Add kernel support for oprofile callgraphs on AVR32

2008-09-22T07:51:01+00:00

This patch adds backtracing capability to oprofile profiling in kernel and user mode on AVR32. This is done by going through the frames on the stack and adding oprofile traces for all return addresses. The code being profiled has to be compiled with frame pointers to make this work.
