A bridge that has been set up by firmware to cover multiple PCI buses but doesn't actually have anything connected behind some of them caused us to use the incorrect maxmimum bus number span when scanning the bridge chip. Problem reported by Tim Saunders, with Russell King suggesting the fix.

Make sure we order the writes to a newly created page with the page table update that potentially exposes the page to another CPU. This is a no-op on any architecture where getting the page table spinlock will already do the ordering (notably x86), but other architectures can care.

From: Lars Ellenberg <Lars.Ellenberg@linbit.com> Add a memory barrier to the assembly checksum code - the code was copied straight from the i386 one, and the patch resyncs the code with the original. I'll check if the original code can be included directly (i.e. "#include") after 2.6.9. Without this patch, every 2.6 UML release corrupts the checksum of every UDP fragmented packet with size >= MTU (verified by various people, we all agree on this issue; nobody reported "Works fine here"). The corrupted packets are not accepted, thus blocking any kind of communication with large-sized UDP packets. In fact, I've even dissected the UML -> host traffic before and after this patch with Ethereal - and it always reported an incorrect checksum for fragmented UDP packets before and always correct after applying the patch.

Currently, ubd=sync is different from replacing ubd#= with ubd#s=. This is against Principle of Least Surprise, so remove this difference. Also the current ubd=sync behaviour is completely useless: it is to make sure that when the kernel has synched its I/O to the virtual disk, the host does not invalidate this with his caching; this causes ReiserFS corruption. But since actually we call end_request() only after the io_thread has done its work, we never lie to the block layer. Using O_SYNC as we do when replacing ubd#= with ubd#s= is enough. Signed-off-by:

From: BlaisorBlade <blaisorblade_spam@yahoo.it>, Chris Wright <chrisw@osdl.org> Avoid deadlocking onto the request lock in the UBD driver, i.e. don't lock the queue spinlock when called from the request function. In detail: Rename ubd_finish() to __ubd_finish() and remove ubd_io_lock from it. Add wrapper, ubd_finish(), which grabs lock before calling __ubd_finish(). Update do_ubd_request to use the lock free __ubd_finish() to avoid deadlock. Also, apparently prepare_request is called with ubd_io_lock held, so remove locks there. Signed-off-by:

Makes the UML build system work well even under parallel make (tested, so far, even with -j50). Please notice that it must be updated for every makefile change. Or better, every makefile change must use correct dependencies (and they are easy to miss). Signed-off-by:

Extraversion in arch/um/Makefile is not needed in mainline, but just for separate patches; also, they should set it in the main Makefile, not elsewhere (Jeff Garzik has just complained). Also remove the dependency from version.h on arch/um/Makefile: it was added because arch/um/Makefile could change the kernel version number. Signed-off-by:

This forces make to use bash rather than whatever /bin/sh is linked to. Without this, since there are some bash extensions used in the build and when /bin/sh isn't bash, then the build fails without a clear error message. Signed-off-by:

If arch/$(ARCH)/Makefile is included before adding -O2 (and the rest) to CFLAGS, I must duplicate the addition of it to USER_CFLAGS for UML. So let's fix this. Also, the below code is useless, since if CONFIG_DEBUG_INFO is y, then CONFIG_FRAME_POINTER is always y. ifeq ($(CONFIG_DEBUG_INFO),y) CFLAGS := $(subst -fomit-frame-pointer,,$(CFLAGS)) endif Signed-off-by:

The patch below by Roland McGrath fixes two bugs in the implementation of the selinux_file_mprotect hook: It calls selinux_file_mmap, which has two problems. First, the stacked security module will get both mmap and mprotect callbacks for an mprotect call, which is wrong. Secondly, the vm_flags value contains VM_* bits, and these do not match the MAP_* bits of the same name or function, so it passes bogus flags and causes every mprotect to be treated as if MAP_SHARED were in use. The patch shares the common code while not having one function call the other, and fixes these two bugs. Signed-off-by:

Derive process start times from the posix_clock_monotonic notion of uptime instead of "jiffies", consistent with the earlier change to /proc/uptime itself. (http://linus.bkbits.net:8080/linux-2.5/cset@3ef4851dGg0fxX58R9Zv8SIq9fzNmQ?na%0Av=index.html|src/.|src/fs|src/fs/proc|related/fs/proc/proc_misc.c) Process start times are reported to userspace in units of 1/USER_HZ since boot, thus applications as procps need the value of "uptime" to convert them into absolute time. Currently "uptime" is derived from an ntp-corrected time base, but process start time is derived from the free-running "jiffies" counter. This results in inaccurate, drifting process start times as seen by the user, even if the exported number stays constant, because the users notion of "jiffies" changes in time. It's John Stultz's patch anyways, which I only messed up a bit, but since people started trading signed-off lines on lkml: Signed-off-by:

This patch is for removing obsolete system calls from m32r kernel, such as old_mmap and old_select. * arch/m32r/kernel/entry.S: - Remove an obsolete system call, old_mmap, from the syscall table. * arch/m32r/kernel/sys_m32r.c: - Remove obsolete system calls, old_mmap() and old_select(). - do_mmap2() is renamed to sys_mmap2(). * CAUTION (for m32r users): The new kernel (applied this patch) does not have a backward compatibility. The new kernel and old library pair does not work. So, those who want to use the new kernel must use a new version of glibc (the GNU C library), which uses the "mmap2(_NR_mmap2)" syscall for __mmap() instead of the "old_mmap(__NR_mmap)". The new glibc package, libc6_2.3.2.ds1-16.0.3_m32r.deb, is provided on the following site, please apt-get/download it and upgrade. http://debian.linux-m32r.org/dists/03_cambrian/main/binary-m32r/Signed-off-by:Hirokazu Takata <takata@linux-m32r.org> Signed-off-by:

This patch fixes the system call table for m32r. The latest kernel cannot be linked for m32r, because the following experimental syscalls doesn't exist in the prepatch kernel of bk-tree. * include/asm-m32r/unistd.h: - Remove syscalls from #285(perfctr_info) to #293(keyctl). * arch/m32r/kernel/entry.S: ditto.

The post-2.6.8 recent tweaks to the page writeback thresholding code seems to be doing the wrong thing for small unmapped_ratios - nathans had a few problems with it. The problem it was trying to fix is minor and fairly theoretical anyway, so back it out to the old code. Signed-off-by:

- Remove the setting of CLOCK_REALTIME and CLOCK_MONOTONIC resolution according to the interpolator resolution since this causes periodic timer signals to fail. The clocks will still be high-resolution but the "resolution" reported reflects the timer intervals possible via timer_settime (also more conformant to what the Single Unix Specification says). - Make the IA64 clock_gettime fastcall fall back on negative clock numbers instead of returning CLOCK_REALTIME.
