[PATCH v3] ARM: signal: fix armv7-m build issue in sigreturn_codes.S

by Victor Kamensky

Hi, Here is version 3 of fix to armv7-m build failure in sigreturn_codes.S. It is based on .org directive Dave's suggestion on last email in [1]. It uses conditional compilation and it uses .org directive to keep sigreturn_codes layout. Note I did not use ARM and THUMB macros because those switch between CONFIG_THUMB2_KERNEL and not. On v7a kernel we need both arm and thumb snipets regardless of CONFIG_THUMB2_KERNEL setting. And conditional compilation only kicks in with CONFIG_CPU_THUMBONLY, for that local ARM_INSTR macro is created. Version 1 [1] used conditional compilation and added thumb2 nop instructions in CONFIG_CPU_THUMBONLY Version 2 [2] tried to use '.acrh armv4t' directive to allow both arm and thumb2 opcodes, but solution deemed to be too fragile. Fix was tested linux-next with efm32_defconfig build (along with few other fixes) rmk-next BE/LE arndale build/boot and LTP rt_sigaction0? tests run Dave, I've added your name with Suggested-by tag, please let me know if it is not OK with you, I'll remove it then. Uwe, is it possible for you to test that this fix runs on efm32? Sorry, for multiple requests.

[PATCH V2] ARM:clps711x:Enable ARM_PATCH_PHYS_VIRT by default

by panchaxari

ARM_PATCH_PHYS_VIRT is enabled by default for clps711x systems Introduction of this config as default will enable phy-to-virt and virt-to-phy translation function at boot and module loading time and enforce dynamic reallocation of memory. This config is mutually exclusive to XIP_KERNEL, which is used in systems with NOR flash devices Requesting platform maintainers to evaluate the changes on the board and comment on the changes, as I dont have the board for testing.

[PATCH] ARM: signal: fix armv7-m build issue in sigreturn_codes.S

by Victor Kamensky

Hi, Here is proposal for armv7-m build failure in sigreturn_codes.S. The armv7-m build issue was discussed in [1]. Proposed solution is based on conditional compilation. If CONFIG_CPU_THUMBONLY is set instead of arm opcodes nops in thumb mode are used. I've tried to wrap conditional compilation as nice as I found possible. Other suggestions/approaches are welcome. Fix was tested: linux-next with efm32_defconfig build (along with few other fixes) rmk-next BE/LE arndale build/boot and LTP rt_sigaction0? tests run Uwe, is it possible for you to test that the fix runs on efm32. Also if the platform can run LTP, you give a spin to LTP rt_sigaction0? tests that would be great. It is known that this tests covers code under change. If folks don't like this fix, I have another variant as I mention in [1] that backs out 574e2b5111e13827da501771b27d92e6e3f2e3d7 (ARM: signal: sigreturn_codes should be endian neutral to work in BE8) and use asm/opcodes to byteswap manually crafted instructions.
