Adds an expert Kconfig option, CONFIG_COREDUMP, which allows disabling of core dump. This saves approximately 2.6k in the compiled kernel, and complements CONFIG_ELF_CORE, which now depends on it. CONFIG_COREDUMP also disables coredump-related sysctls, except for suid_dumpable and related functions, which are necessary for ptrace.

The PA-RISC tool chain seems to have some problem with correct read/write attributes on sections. This causes problems when the const sections are fixed up for other architecture to only contain truly read-only data. Disable const sections for PA-RISC This can cause a bit of noise with modpost.

There is no known reason for this option to be unavailable on other archs than x86. They just need to call enable_sched_clock_irqtime() if they have a sufficiently finegrained clock to make it working. Move it to the general option and let the user choose between it and pure tick based or virtual cputime accounting. Note that virtual cputime accounting already performs a finegrained irqtime accounting. CONFIG_IRQ_TIME_ACCOUNTING is a kind of middle ground between tick and virtual based accounting. So CONFIG_IRQ_TIME_ACCOUNTING and CONFIG_VIRT_CPU_ACCOUNTING are mutually exclusive choices.
