2009-07-03x86, kvm: Fix section mismatches in kvm.cRakib Mullick
The function paravirt_ops_setup() has been refering the variable no_timer_check, which is a __initdata. Thus generates the following warning. paravirt_ops_setup() function is called from kvm_guest_init() which is a __init function. So to fix this we mark paravirt_ops_setup as __init. The sections-check output that warned us about this was: LD arch/x86/built-in.o WARNING: arch/x86/built-in.o(.text+0x166ce): Section mismatch in reference from the function paravirt_ops_setup() to the variable .init.data:no_timer_check The function paravirt_ops_setup() references the variable __initdata no_timer_check. This is often because paravirt_ops_setup lacks a __initdata annotation or the annotation of no_timer_check is wrong.

2009-07-03x86: Fix fixmap page order for FIX_TEXT_POKE0,1Mathieu Desnoyers
Masami reported: > Since the fixmap pages are assigned higher address to lower, > text_poke() has to use it with inverted order (FIX_TEXT_POKE1 > to FIX_TEXT_POKE0). I prefer to just invert the order of the fixmap declaration. It's simpler and more straightforward. Backward fixmaps seems to be used by both x86 32 and 64. It's really rare but a nasty bug, because it only hurts when instructions to patch are crossing a page boundary. If this happens, the fixmap write accesses will spill on the following fixmap, which may very well crash the system. And this does not crash the system, it could leave illegal instructions in place. Thanks Masami for finding this. It seems to have crept into the 2.6.30-rc series, so this calls for a -stable inclusion.

2009-07-03parisc: ensure broadcast tlb purge runs single threadedHelge Deller
The TLB flushing functions on hppa, which causes PxTLB broadcasts on the system bus, needs to be protected by irq-safe spinlocks to avoid irq handlers to deadlock the kernel. The deadlocks only happened during I/O intensive loads and triggered pretty seldom, which is why this bug went so long unnoticed.

2009-07-03parisc: fix "delay!" timer handlingGrant Grundler
Rewrote timer_interrupt() to properly handle the "delayed!" case. If we used floating point math to compute the number of ticks that had elapsed since the last timer interrupt, it could take up to 12K cycles (emperical!) to handle the interrupt. Existing code assumed it would never take more than 8k cycles. We end up programming Interval Timer to a value less than "current" cycle counter. Thus have to wait until Interval Timer "wrapped" and would then get the "delayed!" printk that I moved below. Since we don't really know what the upper limit is, I prefer to read CR16 again after we've programmed it to make sure we won't have to wait for CR16 to wrap. Further, the printk was between reading CR16 (cycle couner) and writing CR16 (the interval timer). This would cause us to continue to set the interval timer to a value that was "behind" the cycle counter. Rinse and repeat. So no printk's between reading CR16 and setting next interval timer. Tested on A500 (550 Mhz PA8600).

I think I have it right but recognize I might not. TODO: I wanted to use "do_div()" in order to get both remainder and value back with one division op.

2009-07-03parisc: fix ldcw inline assemblerHelge Deller
There are two reasons to expose the memory *a in the asm: 1) To prevent the compiler from discarding a preceeding write to *a, and 2) to prevent it from caching *a in a register over the asm. The change has had a few days testing with a SMP build of 2.6.22.19 running on a rp3440. This patch is about the correctness of the __ldcw() macro itself. The use of the macro should be confined to small inline functions to try to limit the effect of clobbering memory on GCC's optimization of loads and stores.

We can run a 32-bit kernel on boxes with an IOMMU, so we need pci_unmap_addr() etc. to work -- without it, drivers will leak mappings.
