The ARM allmodconfig build currently warngs because of the ux500 crypto driver not working well with the jump label implementation that we started using for dynamic debug, which breaks building with 'gcc -O0': In file included from /git/arm-soc/include/linux/jump_label.h:105:0, from /git/arm-soc/include/linux/dynamic_debug.h:5, from /git/arm-soc/include/linux/printk.h:289, from /git/arm-soc/include/linux/kernel.h:13, from /git/arm-soc/include/linux/clk.h:16, from /git/arm-soc/drivers/crypto/ux500/hash/hash_core.c:16: /git/arm-soc/arch/arm/include/asm/jump_label.h: In function 'hash_set_dma_transfer': /git/arm-soc/arch/arm/include/asm/jump_label.h:13:7: error: asm operand 0 probably doesn't match constraints [-Werror] asm_volatile_goto("1:\n\t" Turning off compiler optimizations has never really been supported here, and it's only used when debugging the driver. I have not found a good reason for doing this here, other than a misguided attempt to produce more readable assembly output. Also, the driver is only used in obsolete hardware that almost certainly nobody will spend time debugging any more. This just removes the -O0 flag from the compiler options.
