Raw Normal View History

Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

[ARM] Cleanup ARM includes arch/arm/kernel/entry-armv.S has contained a comment suggesting that asm/hardware.h and asm/arch/irqs.h should be moved into the asm/arch/entry-macro.S include. So move the includes to these two files as required. Add missing includes (asm/hardware.h, asm/io.h) to asm/arch/system.h includes which use those facilities, and remove asm/io.h from kernel/process.c. Remove other unnecessary includes from arch/arm/kernel, arch/arm/mm and arch/arm/mach-footbridge. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

[ARM] 4185/2: entry: introduce get_irqnr_preamble and arch_ret_to_user get_irqnr_preamble allows machines to take some action before entering the get_irqnr_and_base loop. On iop we enable cp6 access. arch_ret_to_user is added to the userspace return path to allow individual architectures to take actions, like disabling coprocessor access, before the final return to userspace. Per Nicolas Pitre's note, there is no need to cp_wait on the return to user as the latency to return is sufficient.
