2017-05-01avr32: remove support for AVR32 architectureHans-Christian Noren Egtvedt1-105/+0
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.

2015-04-13avr32: fix integer overflow in ELF_ET_DYN_BASEAndrey Ryabinin1-1/+1
Almost all arches define ELF_ET_DYN_BASE as 2/3 of TASK_SIZE. Though it seems that some architectures do this in a wrong way. The problem is that 2*TASK_SIZE may overflow 32-bits so the real ELF_ET_DYN_BASE becomes wrong. Fix this overflow by dividing TASK_SIZE prior to multiplying: (TASK_SIZE / 3 * 2) Signed-off-by: Andrey Ryabinin <a.ryabinin@samsung.com> Acked-by: Hans-Christian Egtvedt <egtvedt@samfundet.no>

2012-10-06cross-arch: don't corrupt personality flags upon exec()Jiri Kosina1-1/+2
Historically, the top three bytes of personality have been used for things such as ADDR_NO_RANDOMIZE, which made sense only for specific architectures. We now however have a flag there that is general no matter the architecture (UNAME26); generally we have to be careful to preserve the personality flags across exec(). This patch tries to fix all architectures that forcefully overwrite personality flags during exec() (ppc32 and s390 have been fixed recently by commits f9783ec862ea ("[S390] Do not clobber personality flags on exec") and 59e4c3a2fe9c ("powerpc/32: Don't clobber personality flags on exec") in a similar way already).

2009-12-16elf: kill USE_ELF_CORE_DUMPChristoph Hellwig1-1/+0
Currently all architectures but microblaze unconditionally define USE_ELF_CORE_DUMP. The microblaze omission seems like an error to me, so let's kill this ifdef and make sure we are the same everywhere.
