| * ARM: nomadik: bump the IRQ numbers againLinus Walleij2013-01-031-39/+39
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Bump the IRQ numbers from offset at 1 (right above NO_IRQ) to 32. This is the painful way to learn that if you're using SPARSE_IRQ and avoid to define .nr_irqs in your machine, the first 16 IRQs will be pre-allocated, and the IRQdomain code (as the VIC core code before it) will then assume that all IRQ descriptors are pre-allocated, and 16 of them are - by somebody else. So mapping the IRQs will fail in irq_create_mapping(). Moving the offset upward rids us of this problem.

* | ARM: highbank: fix secondary boot and hotplugRob Herring2013-01-072-12/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With commit 384a290 (ARM: gic: use a private mapping for CPU target interfaces), wake-up IPIs now go to all cores as the gic cpu interface numbering may not follow core numbering. This broke secondary boot on highbank since the boot address was already set for all secondary cores, this caused all cores to boot before the kernel was ready. Fix this by moving the setting of the jump address to highbank_boot_secondary instead of highbank_smp_prepare_cpus and highbank_cpu_die. Also, clear the address when we boot. This prevents cores from booting before they are actually triggered and is also necessary to get suspend/resume to work.

For some reason, the CLUSTERID on highbank is 9, so the reg value needs to be 0x90n to quiet the warnings.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since udev-182, udev no longer creates device nodes under /dev and this has to be managed by the kernel devtmpfs filesystem. This means that a kernel built with the current OMAP2+ config will not boot on a system with a recent udev. Also, it is good to have /dev automatically mounted since some non-initramfs based setups assumes this and don't manually mount it.

Note that amd64 variants of current_user_stack_pointer/compat_user_stack_pointer do *not* rely on pt_regs having been through FIXUP_TOP_OF_STACK. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Cross-architecture equivalent of rdusp(); default is user_stack_pointer(current_pt_regs()) - that works for almost all platforms that have usp saved in pt_regs. The only exception from that is ia64 - we want memory stack, not the backing store for register one. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

This patch uses the correct address for REALVIEW_EB11MP_PRIV_MEM_BASE.

On uniprocessor CPUs, this is defined as zero and therefore no flushing will take place. Rather than invent a new interface for UP systems, instead use our SMP_ON_UP patching code to read the LoUU from the CLIDR instead.
