The meye hardware needs to access the main memory for DMA using 32 bit addresses. The previous version of the meye driver used dma_addr_t types to build those addresses and ensured that sizeof(dma_addr_t) = 4 by disabling HIGHMEM64G in Kconfig. However, this way of doing it also makes meye unavailable on some kernel configurations. As Arjan said previously, future Fedora kernels may have HIGHMEM64G activated by default (davej says it won't happen, at least for now...). Other distributions may do the same and this will require meye users to recompile the whole kernel. The attached patch makes the meye driver use dma_addr_t addresses internally, but converts them to u32 before giving them to the hardware. Signed-off-by:

Unfortunately the restoring of SPE state was causing data corruption since we were restoring based on the size of the altivec context and not the SPE context. Also, fixed setting of last_task_used_spe on start_thread, flush_thread, and exit_thread. Signed-off-by:

When adding or deleting from the source list make sure to find matches by comparing against the new source address, not the group address. Also, check each addr in the list rather than just the first one. And, finally, only delete from list when there's a match rather than vice-versa. Drop the effort to keep list sorted, since it's not done on full-state api and can create an sl_addr entry that the delta api won't be able to delete. Without these fixes sl_count can be corrupted which can allow for kernel memory corruption. Signed-off-by:

- fix pfm_force_terminate() to really cleanup the state. There was a bug affecting sessions which use PFM_FL_OVFL_BLOCK flag. It could lead to an assertion failure in pfm_load_regs() in the case where the owner of the session died unexpectedly. The fix is to do the full unload operation. - simplifies the debug output in pfm_flush_pmds() - simplifies the debug output in pfm_overflow_handler() - fix a minor typos in a comment in pfm_flush(). signed-off-by:

I recently learnt that limiting RAM with by using only "mem=xxxM" is no good on machines equipped with PCI. In my case (vanilla 2.6.9) the cardbus bridge on my laptop got mapped to the unused RAM area which resulted in wierd errors due to the collision. The right solution is to use "mem=" together with "memmap=" to mark the unused RAM area reserved. Henceforth I force the kernel to use 2016MiB by passing "mem=2016M memmap=32M#2016M" instead of just "mem=2016M". Signed-off-by:

This patch fixes a problem where /dev/urandom can return duplicate values when two processors read from it at the same time. It relies on the fact that we already are taking a lock in add_entropy_words(), and atomically hashes in some freshly mixed in data into the returned randomness. Signed-off-by:

As of 2.6.10-rc3, the following is needed to allow various userland packages (sysvinit, dhcp, ppp, libcap, libpcap, lilo) to compile as parts that userland needs (e.g. for ioctls) is in files with stuff userland isn't allowed to see. This adds __KERNEL__ around <linux/ata.h> and some defines (<linux/ata.h> isn't needed by userland, and is unhappy right now). sysvinit and some other packages need <linux/hdreg.h> for HDIO_DRIVE_CMD and other IOCTL things. In <linux/types.h> we were unsafely typedef'ing __le64/__be64 as __u64 only exists when __GNUC__ && !__STRICT_ANSI__ (causing libcap to fail, for example). Finally, <asm/atomic.h> provides routines userland simply cannot use on all arches, but <linux/filter.h> is needed by iputils for example. While not all arches put __KERNEL__ around their header, on MIPS including this header currently blows up the build. Signed-off-by:

It turns out there are more issues with our VPA code: 1. vpa_init doesnt report errors when it fails. This was masking a bug where the VPA spanned 2 pages and phyp failed to register it. 2. We call idle_setup before we initialise the boot cpus vpa. This means we never select the shared processor idle loop. 3. We dont call vpa_init on UP kernels. Signed-off-by:

ppc64 has a global called "pci_probe_only" which, when set, prevents the arch PCI code from calling pci_assign_unassigned_resources(). This was cleared by pmac so far, but a bug in the definition of the variable make that ineffective until 2.6.10, and so we never called pci_assign_unassigned_resources(). With 2.6.10, that bug was fixed and so we now call it, which results in some problems. Some devices who have perfectly valid assigned addresses by firmware end up beeing moved around anyway, which is a BAD thing can can break boot on some machines since it breaks the relationship between addresses in Open Firmware device-tree and actual location of PCI devices. (Some low level things like the PIC are ioremap'ed based on their OF address, way before the PCI based ASIC hosting them has been found). This also break the "offb" default framebuffer driver since the video card ends up beeing moved around as well. For now, the fix is to set pci_probe_only on pmac, thus reverting to the old behaviour. In the long run, it would be interesting to "fix" pci_assign_unassigned_resources() so that it does what it's name claims, and only assigns things that have been left unassigned instead of moving things around gratuituously...

Sometimes /proc/<pid>/status shows VmLib: 42949..... kB. mprotect_fixup must note oldflags on entry: if vma_merge is successful, vma->vm_flags afterwards may be either the oldflags or the newflags, and the extent of the change will be less than the extent of the vma. And let's use unsigned long for these flags throughout. Signed-off-by:

In some cases /proc/<pid>/status shows VmLib: 42949..... kB. If READ_IMPLIES_EXEC then the break area is VM_EXEC, but omitted from exec_vm since do_brk contains no __vm_stat_account call. Later munmaps count its pages out of exec_vm, hence (exec_vm - VmExe) can go negative. do_brk is right not to call __vm_stat_account, its pages shouldn't need to be counted. What's wrong is that __vm_stat_account is counting all the VM_EXEC pages, whereas (to mimic 2.4 and earlier 2.6) it should be leaving VM_WRITE areas and non-vm_file areas out of exec_vm. VmLib may still appear larger than before - where a READ_IMPLIES_EXEC personality makes what was a readonly mapping of a file now executable e.g. /usr/lib/locale stuff. And a program which mprotects its own text as writable will appear with wrapped VmLib: sorry, but while it's worth showing ordinary programs as ordinary, it's not worth much effort to avoid showing odd ones as odd.
