This reverts commit c7b2eff0. Hugh Dickins explains: "It seems too little tested: "losetup -d /dev/loop0" fails with EINVAL because nothing sets lo_thread; but even when you patch loop_thread() to set lo->lo_thread = current, it can't survive more than a few dozen iterations of the loop below (with a tmpfs mounted on /tst): j=0 cp /dev/zero /tst while : do let j=j+1 echo "Doing pass $j" losetup /dev/loop0 /tst/zero mkfs -t ext2 -b 1024 /dev/loop0 >/dev/null 2>&1 mount -t ext2 /dev/loop0 /mnt umount /mnt losetup -d /dev/loop0 done it collapses with failed ioctl then BUG_ON(!bio). I think the original lo_done completion was more subtle and safe than the kthread conversion has allowed for." Signed-off-by:

Reworked the way RAM regions are defined. Instead of coding all the variations for each board type we now just configure RAM base and size in the usual Kconfig setup. This much simplifies the code, and makes it a lot more flexible when setting up new boards or board varients. Signed-off-by:

Take two, now without spurious whitespace :( Applies to git & 2.6.17-rc6 CONFIG_DEBUG_STACKOVERFLOW existed for x86_64 in 2.4, but seems to have gone AWOL in 2.6. I've pretty much just copied this over from the 2.4 code, with appropriate tweaks for the 2.6 kernel, plus a bugfix. I'd personally rather see it printed out the way other arches do it, i.e. bytes-remaining-until-overflow, rather than having to do the subtraction yourself. Also, only 128 bytes remaining seems awfully late to issue a warning. But I'll start here :) Signed-off-by:

CC drivers/pci/msi-apic.o In file included from include/asm/msi.h:11, from drivers/pci/msi.h:71, from drivers/pci/msi-apic.c:8: include/asm/smp.h:103: error: syntax error before '->' token akpm: nasty. It appears to be static inline unsigned int cpu_mask_to_apicid(cpumask_t cpumask) conflicting with include/asm-x86_64/mach_apic.h's #define cpu_mask_to_apicid (genapic->cpu_mask_to_apicid) And I don't know which patch in rc4-mm1 triggered this. Fixing this in the .c file seems wrong. Including asm/smp.h instead of linux/smp.h seems wrong too. Need that .config.

Intel now has support for Architectural Performance Monitoring Counters ( Refer to IA-32 Intel Architecture Software Developer's Manual http://www.intel.com/design/pentium4/manuals/253669.htm ). This feature is present starting from Intel Core Duo and Intel Core Solo processors. What this means is, the performance monitoring counters and some performance monitoring events are now defined in an architectural way (using cpuid). And there will be no need to check for family/model etc for these architectural events. Below is the patch to use this performance counters in nmi watchdog driver. Patch handles both i386 and x86-64 kernels. Signed-off-by:

On some i386/x86_64 systems, sending an NMI IPI as a broadcast will reset the system. This seems to be a BIOS bug which affects machines where one or more cpus are not under OS control. It occurs on HT systems with a version of the OS that is not compiled without HT support. It also occurs when a system is booted with max_cpus=n where 2 <= n < cpus known to the BIOS. The fix is to always send NMI IPI as a mask instead of as a broadcast. Signed-off-by:

Appended patch fixes the "APIC error on CPUX: 00(40)" observed during bootup. From SDM Vol-3A "Valid Interrupt Vectors" section: "When an illegal vector value (0-15) is written to an LVT entry and the delivery mode is Fixed, the APIC may signal an illegal vector error, with out regard to whether the mask bit is set or whether an interrupt is actually seen on input."

Keith Owens authored
x86_64 and i386 behave inconsistently when sending an IPI on vector 2 (NMI_VECTOR). Make both behave the same, so IPI 2 is sent as NMI. The crash code was abusing send_IPI_allbutself() by passing a code instead of a vector, it only worked because crash knew about the internal code of send_IPI_allbutself(). Change crash to use NMI_VECTOR instead, and remove the comment about how crash was abusing the function. This patch is a pre-requisite for fixing the problem where sending an IPI as NMI would reboot some Dell Xeon systems. I cannot fix that problem while crash continus to abuse send_IPI_allbutself(). It also removes the inconsistency between i386 and x86_64 for NMI_VECTOR. That will simplify all the RAS code that needs to bring all the cpus to a clean stop, even when one or more cpus are spinning disabled. Signed-off-by:

Currently CONFIG_REORDER uses -ffunction-sections for all code; however, creating a separate section for each function is not useful for modules and just adds bloat. Moving this option from CFLAGS to CFLAGS_KERNEL shrinks module object files (e.g., the module tree for a kernel built with most drivers as modules shrinked from 54M to 46M), and decreases the number of sysfs files in /sys/module/*/sections/ directories.

During some profiling I noticed that default_idle causes a lot of memory traffic. I think that is caused by the atomic operations to clear/set the polling flag in thread_info. There is actually no reason to make this atomic - only the idle thread does it to itself, other CPUs only read it. So I moved it into ti->status. Converted i386/x86-64/ia64 for now because that was the easiest way to fix ACPI which also manipulates these flags in its idle function.
