Hi all, Wrong usage of 2nd parameter in reserve_early call. 66/75: reserve_early(start_bad, last_bad - start_bad, "BAD RAM"); ^^^^^^^^^^^^^^^^^^^^ The correct way is to use 'end' address and not 'size'. As a bonus a fix to the printk format. Signed-off-by: Daniele Calore <orkaan@orkaan.org> Acked-by: Yinghai Lu <yinghai@kernel.org> Signed-off-by: Ingo Molnar <mingo@elte.hu>

Petr Tesarik noticed that I'd bungled the syscall_get_arguments code for 64-bit kernels, so it inverted the order of the syscall argument registers. Petr wrote a patch to fix that, and I've amended it to fix the same braino in the syscall_set_arguments code.

Impact: fix missing CPUs in /proc/cpuinfo after CPU hotunplug/hotreplug In my test, I found that if a cpu has been offline, the next cpus may not be shown in the /proc/cpuinfo. if one read() cannot consume the whole /proc/cpuinfo, c_start() will be called again in the next read() calls. And *pos has been increased by 1 by the caller(seq_read()). if this time the cpu#*pos is offline, c_start() will return NULL, and the next cpus can not be shown. this fix use next_cpu_nr(*pos - 1, cpu_online_map) to search the next unshown cpu. the most easy way to reproduce this bug: 1) offline cpu#1 (cpu#0 is online) 2) dd ibs=2 if=/proc/cpuinfo the result is that only cpu#0 is shown. cpu#2 and cpu#3 .... cannot be shown in /proc/cpuinfo it's bug.

Impact: make warning message disappear - functionality unchanged Problems with bogus IRQ0 override of those laptops should be fixed with commits x86: SB600: skip IRQ0 override if it is not routed to INT2 of IOAPIC x86: SB450: skip IRQ0 override if it is not routed to INT2 of IOAPIC that introduce early-quirks based on chipset configuration. For further information, see http://bugzilla.kernel.org/show_bug.cgi?id=11516 Instead of removing the related dmi-quirks completely we'd like to keep them for (at least) one kernel version -- to double-check whether the early-quirks really took effect. But the dmi-quirks need to be called after early-quirks are executed. With this patch calling sequence for dmi-quriks is changed as follows: acpi_boot_table_init() (dmi-quirks) ... early_quirks() (detect bogus IRQ0 override) ... acpi_boot_init() (late dmi-quirks and setup IO APIC) Note: Plan is to remove the "late dmi-quirks" with next kernel version.

Neil Horman authored
There's a corner case in 32 bit x86 kdump at the moment. When the box panics via nmi, we call bust_spinlocks(1) to disable sensitivity to the console_sem (allowing us to print to the console in all cases), but we don't call crash_kexec, until after we call bust_spinlocks(0), which re-enables console_sem sensitivity. The result is that, if we get an nmi while the console_sem is held and kdump is configured, and we try to print something to the console during kdump shutdown (which we often do) we deadlock the box. The fix is to simply do what 64 bit die_nmi does which is to not call bust_spinlocks(0) until after we call crash_kexec. Patch below tested successfully by me.

Running machine checks with interrupt on is a extremly bad idea. The machine check handler only runs when the system is broken and needs to finish as quickly as possible. Remove the respective bogus post 2.6.27 regression and call the machine check vector directly again. This removes only code.

Impact: fix hung bootup and other misbehavior on certain laptops On some more HP laptops BIOS reports an IRQ0 override but the SB600 chipset is configured such that timer interrupts go to INT0 of IOAPIC. Check IRQ0 routing and if it is routed to INT0 of IOAPIC skip the timer override.

Commit f06febc9 ("timers: fix itimer/ many thread hang") introduced a new task_cputime interface and subsequently only converted binfmt_elf over to it. This results in the build for binfmt_elf_fdpic blowing up given that p->signal->{u,s}time have disappeared from underneath us. Apply the same trivial fix from binfmt_elf to binfmt_elf_fdpic.

We're trying to keep the !CONFIG_SHMEM tiny-shmem.c (using ramfs without swap) in synch with CONFIG_SHMEM shmem.c (and mpm is preparing patches to combine them). I was glad to see EXPORT_SYMBOL_GPL(shmem_file_setup) go into shmem.c, but why not support DRM-GEM when !CONFIG_SHMEM too? But caution says still depend on MMU, since !CONFIG_MMU is.. different.

This gets rid of an annoying warning in ehci-hcd.c when DEBUG isn't enabled: warning: label 'err_debug' defined but not used by moving it inside the already-existing #ifdef DEBUG, so that it matches the goto.

Yes, this will probably be switched over to a cleaner model anyway, but in the meantime I don't want to see the 'unused variable' warnings that come from the disgusting #ifdef code. Make the special case be a nice inlien function of its own, clean up the code, and make the warning go away. I wish people didn't write code that gets (valid) warnings from the compiler, but I'll limit my fixes to code that I actually care about (in this case just because I see the warning and it annoys me).
