What: Support for NEC DDB5074 and DDB5476 evaluation boards. When: June 2006 Why: Board specific code doesn't build anymore since ~2.6.0 and no users have complained indicating there is no more need for these boards. This should really be considered a last call. Who: Ralf Baechle <ralf@linux-mips.org> -

The low level PCI DMA mapping functions should handle it in most cases. This should fix problems with depleting the DMA zone early. The old code used precious GFP_DMA memory in many cases where it was not needed. Signed-off-by:

ATI chipsets tend to generate double timer interrupts for the local APIC timer when both the 8254 and the IO-APIC timer pins are enabled. This is because they route it to both and the result is anded together and the CPU ends up processing it twice. This patch changes check_timer to disable the 8254 routing for interrupt 0. I think it would be safe on all chipsets actually (i tested it on a couple and it worked everywhere) and Windows seems to do it in a similar way, but to be conservative this patch only enables this mode on ATI (and adds options to enable/disable too) Ported over from a similar x86-64 change. I reused the ACPI earlyquirk infrastructure for the ATI bridge check, but tweaked it a bit to work even without ACPI. Inspired by a patch from Chuck Ebbert, but redone.

A recent change to compat. dev_ifconf() in fs/compat_ioctl.c causes ifconf data to be truncated 1 entry too early when copying it to userspace. The correct amount of data (length) is returned, but the final entry is empty (zero, not filled in). The for-loop 'i' check should use <= to allow the final struct ifreq32 to be copied. I also used the ifconf-corruption program in kernel bugzilla #4746 to make sure that this change does not re-introduce the corruption. Signed-off-by:

While testing kexec and kdump we hit problems where the new kernel would freeze or instantly reboot. The easiest way to trigger it was to kexec a kernel compiled for CONFIG_M586 on an athlon cpu. Compiling for CONFIG_MK7 instead would work fine. The patch fixes a few problems with the kexec inline asm. Signed-off-by:

DASD allows to open a device as soon as gendisk is registered, which means the device is a fake device (capacity=0) and we do know nothing about blocksize and partitions at that point of time. In case the device is opened by someone, the bdev and inode creation is done with the fake device info and the following partition detection code is just using the wrong data. To avoid this modify the DASD state machine to make sure that the open is rejected until the device analysis is either finished or an unformatted device was detected. Signed-off-by:

I have benchmarked this on an x86_64 NUMA system and see no significant performance difference on kernbench. Tested on both x86_64 and powerpc. The way we do file struct accounting is not very suitable for batched freeing. For scalability reasons, file accounting was constructor/destructor based. This meant that nr_files was decremented only when the object was removed from the slab cache. This is susceptible to slab fragmentation. With RCU based file structure, consequent batched freeing and a test program like Serge's, we just speed this up and end up with a very fragmented slab - llm22:~ # cat /proc/sys/fs/file-nr 587730 0 758844 At the same time, I see only a 2000+ objects in filp cache. The following patch I fixes this problem. This patch changes the file counting by removing the filp_count_lock. Instead we use a separate percpu counter, nr_files, for now and all accesses to it are through get_nr_files() api. In the sysctl handler for nr_files, we populate files_stat.nr_files before returning to user. Counting files as an when they are created and destroyed (as opposed to inside slab) allows us to correctly count open files with RCU. Signed-off-by:

This patch adds new tunables for RCU queue and finished batches. There are two types of controls - number of completed RCU updates invoked in a batch (blimit) and monitoring for high rate of incoming RCUs on a cpu (qhimark, qlowmark). By default, the per-cpu batch limit is set to a small value. If the input RCU rate exceeds the high watermark, we do two things - force quiescent state on all cpus and set the batch limit of the CPU to INTMAX. Setting batch limit to INTMAX forces all finished RCUs to be processed in one shot. If we have more than INTMAX RCUs queued up, then we have bigger problems anyway. Once the incoming queued RCUs fall below the low watermark, the batch limit is set to the default. Signed-off-by:

Implement percpu_counter_sum(). This is a more accurate but slower version of percpu_counter_read_positive(). We need this for Alex's speedup-ext3_statfs patch and for the nr_file accounting fix.

Fix i386 nmi_watchdog that does not meet watchdog timeout condition. It does not hit die_nmi when it should be triggered, because the current nmi_watchdog_tick in arch/i386/kernel/nmi.c never count up alert_counter like this: void nmi_watchdog_tick (struct pt_regs * regs) { if (last_irq_sums[cpu] == sum) { alert_counter[cpu]++; <- count up alert_counter, but if (alert_counter[cpu] == 5*nmi_hz) die_nmi(regs, "NMI Watchdog detected LOCKUP"); alert_counter[cpu] = 0; <- reset alert_counter This patch changes it back to the previous and working version.

Fix a bug in udf where it would write uid/gid = 0 to the disk for files owned by the id given with the uid=/gid= mount options. It also adds 4 new mount options: uid/gid=forget and uid/gid=ignore. Without any options the id in core and on disk always match. Giving uid/gid=nnn specifies a default ID to be used in core when the on disk ID is -1. uid/gid=ignore forces the in core ID to allways be used no matter what the on disk ID is. uid/gid=forget forces the on disk ID to always be written out as -1. The use of these options allows you to override ownerships on a disk or disable ownwership information from being written, allowing the media to be used portably between different computers and possibly different users without permissions issues that would require root to correct.

We're presently getting oopses because Bluetooth (and possibly other) drivers are calling core functions after things have been shut down. So rather than oopsing, let's drop a warning then take avoiding action, so the machine survives. Once all the sub-drivers are fixed up we can remove the take-avoiding-action part. Signed-off-by:

A careful reading of the recent changes to the system call entry/exit paths revealed several problems, plus some things that could be simplified and improved: * 32-bit wasn't testing the _TIF_NOERROR bit in the syscall fast exit path, so it was only doing anything with it once it saw some other bit being set. In other words, the noerror behaviour would apply to the next system call where we had to reschedule or deliver a signal, which is not necessarily the current system call. * 32-bit wasn't doing the call to ptrace_notify in the syscall exit path when the _TIF_SINGLESTEP bit was set. * _TIF_RESTOREALL was in both _TIF_USER_WORK_MASK and _TIF_PERSYSCALL_MASK, which is odd since _TIF_RESTOREALL is only set by system calls. I took it out of _TIF_USER_WORK_MASK. * On 64-bit, _TIF_RESTOREALL wasn't causing the non-volatile registers to be restored (unless perhaps a signal was delivered or the syscall was traced or single-stepped). Thus the non-volatile registers weren't restored on exit from a signal handler. We probably got away with it mostly because signal handlers written in C wouldn't alter the non-volatile registers. * On 32-bit I simplified the code and made it more like 64-bit by making the syscall exit path jump to ret_from_except to handle preemption and signal delivery. * 32-bit was calling do_signal unnecessarily when _TIF_RESTOREALL was set - but I think because of that 32-bit was actually restoring the non-volatile registers on exit from a signal handler. * I changed the order of enabling interrupts and saving the non-volatile registers before calling do_syscall_trace_leave; now we enable interrupts first.
