2007-08-20ensure we don't use bootconsoles after init has been releasedRobin Getz1-0/+11
This is a followup to the cleanups for earlyprintk patch from Gerd Hoffmann http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=69331af79cf29e26d1231152a172a1a10c2df511 This ensures that a bootconsole is unregistered if it is not replaced. The current implementation spews garbage out the bootconsole in this case, since the bootconsole structure is normally in the init section, and is freed, but still used.

2007-08-19KVM: Avoid calling smp_call_function_single() with interrupts disabledAvi Kivity1-0/+4
When taking a cpu down, we need to hardware_disable() it. Unfortunately, the CPU_DYING notifier is called with interrupts disabled, which means we can't use smp_call_function_single(). Fortunately, the CPU_DYING notifier is always called on the dying cpu, so we don't need to use the function at all and can simply call hardware_disable() directly.

2007-08-18x86: properly initialize temp insn buffer for paravirt patchingChris Wright1-0/+2
With commit ab144f5ec64c42218a555ec1dbde6b60cf2982d6 the patching code now collects the complete new instruction stream into a temp buffer before finally patching in the new insns. In some cases the paravirt patchers will choose to leave the patch site unpatched (length mismatch, clobbers mismatch, etc). This causes the new patching code to copy an uninitialized temp buffer, i.e. garbage, to the callsite. Simply make sure to always initialize the buffer with the original instruction stream. A better fix is to audit all the patchers and return proper length so that apply_paravirt() can skip copies when we leave the patch site untouched.

2007-08-18fix random hang in forcedeth driver when using netconsoleTimo Jantunen1-5/+5
If the forcedeth driver receives too much work in an interrupt, it assumes it has a broken hardware with stuck IRQ. It works around the problem by disabling interrupts on the nic but makes a printk while holding device spinlog - which isn't smart thing to do if you have netconsole on the same nic. This patch moves the printk's out of the spinlock protected area. Without this patch the machine hangs hard. With this patch everything still works even when there is significant increase on CPU usage while using the nic.

2007-08-18i386: Fix a couple busy loops in mach_wakecpu.h:wait_for_init_deassert()Satyam Sharma2-2/+4
Use cpu_relax() in the busy loops, as atomic_read() doesn't automatically imply volatility for i386 and x86_64. x86_64 doesn't have this issue because it open-codes the while loop in smpboot.c:smp_callin() itself that already uses cpu_relax(). For i386, however, smpboot.c:smp_callin() calls wait_for_init_deassert() which is buggy for mach-default and mach-es7000 cases. [ I test-built a kernel -- smp_callin() itself got inlined in its only callsite, smpboot.c:start_secondary() -- and the relevant piece of code disassembles to the following: 0xc1019704 <start_secondary+12>: mov 0xc144c4c8,%eax 0xc1019709 <start_secondary+17>: test %eax,%eax 0xc101970b <start_secondary+19>: je 0xc1019709 <start_secondary+17> init_deasserted (at 0xc144c4c8) gets fetched into %eax only once and then we loop over the test of the stale value in the register only, so these look like real bugs to me. With the fix below, this becomes: 0xc1019706 <start_secondary+14>: pause 0xc1019708 <start_secondary+16>: cmpl $0x0,0xc144c4c8 0xc101970f <start_secondary+23>: je 0xc1019706 <start_secondary+14> which looks nice and healthy. ] Thanks to Heiko Carstens for noticing this.

2007-08-16[MATH-EMU]: Fix underflow exception reporting.David S. Miller4-1/+19
The underflow exception cases were wrong. This is one weird area of ieee1754 handling in that the underflow behavior changes based upon whether underflow is enabled in the trap enable mask of the FPU control register. As a specific case the Sparc V9 manual gives us the following description: -------------------- If UFM = 0: Underflow occurs if a nonzero result is tiny and a loss of accuracy occurs. Tininess may be detected before or after rounding. Loss of accuracy may be either a denormalization loss or an inexact result. If UFM = 1: Underflow occurs if a nonzero result is tiny. Tininess may be detected before or after rounding. -------------------- What this amounts to in the packing case is if we go subnormal, we set underflow if any of the following are true: 1) rounding sets inexact 2) we ended up rounding back up to normal (this is the case where we set the exponent to 1 and set the fraction to zero), this should set inexact too 3) underflow is set in FPU control register trap-enable mask The initially discovered example was "DBL_MIN / 16.0" which incorrectly generated an underflow. It should not, unless underflow is set in the trap-enable mask of the FPU csr. Another example, "0x0.0000000000001p-1022 / 16.0", should signal both inexact and underflow. The cpu implementations and ieee1754 literature is very clear about this. This is case #2 above. However, if underflow is set in the trap enable mask, only underflow should be set and reported as a trap. That is handled properly by the prioritization logic in arch/sparc{,64}/math-emu/math.c:record_exception(). Based upon a report and test case from Jakub Jelinek. Signed-off-by: David S.

The other drivers appear to return 0 for a failure, and doing so gives me the max frequency from scaling_cur_frequency and "<unknown>" from cpuinfo_cur_frequency.

2007-08-15[AVR32] Define mmiowb()Haavard Skinnemoen1-0/+2
Add empty definition of mmiowb() since some drivers need it. Uncached writes are strongly ordered on AVR32. They may be delayed if the dcache is busy doing a writeback, but AFAICT that's not what this macro is supposed to deal with, at least on UP systems. We might have to revisit this definition when a SMP-capable AVR32 CPU comes along, depending on how the busses and cache coherency stuff end up being implemented.

2007-08-15[AVR32] Fix bogus pte_page() definitionHaavard Skinnemoen1-3/+1
The current definition of pte_page() masks out valid bits from the physical address, causing vmalloc_to_page() to misbehave. This may lead to everything from mmap() silently accessing the wrong data to "invalid pte" errors dumped by the kernel. Also remove the now-unused definition of PTE_PHYS_MASK. Thanks to Matteo Vit for discovering this bug. Signed-off-by: Haavard Skinnemoen <hskinnemoen@atmel.com>
2007-08-15[AVR32] Simplify pte_alloc_one{,_kernel}Haavard Skinnemoen1-20/+2
There's really no need to retry an allocation with __GFP_REPEAT set. Also, use get_zeroed_page() and __GFP_ZERO to eliminate the extra call to clear_page() afterwards. Signed-off-by: Haavard Skinnemoen <hskinnemoen@atmel.com>
