2010-04-30MIPS: Use CKSEG1ADDR for uncached handlerSebastian Andrzej Siewior
"MIPS: Calculate proper ebase value for 64-bit kernels" 9af43ea080dd5d6c7b34f38261780e5dd43537bc (lmo) rsp. f6be75d03c8870be91e6e2a195648ece04b6bb16 (kernel.org) broke some 64-bit MIPS systems. Before this we were using XKPHYS/cached as ebase and computed the uncached xphsys/unchached address for that area. After that commit ebase became a 32-bit compat address and convert does not work anymore. We now should use CKSEG1 for this. CKSEG1ADDR does just that in 32-bit and 64-bit.

2010-04-30MIPS: Check for accesses beyond the end of the PGD.David Daney
For some combinations of PAGE_SIZE and vmbits, it is possible to have userspace access that are beyond what is covered by the PGD, but within vmbits. Such an access would cause the TLB refill handler to load garbage values for PMD and PTE potentially giving userspace access to parts of the physical address space to which it is not entitled. In the TLB refill hot path, we add a single dsrl instruction so we can check if any bits outside of the range covered by the PGD are set. In the vmalloc side we then separate the bad case from the normal vmalloc case and call tlb_do_page_fault_0 if warranted. This slows us down a bit, but has the benefit of yielding deterministic behavior.

2010-04-30MIPS: die() does not call die notifier chainYury Polyanskiy
The MIPS implementation of die() forgets to call notify_die() and thus notifiers registered via register_die_notifier() are not called. This results in kgdb not being activated on exceptions. The only subtlety is that notify_die declares its regs argument w/o const, so the const had to be removed from mips die() as well.

Same issues as SD card detection: One of both is always triggering and the handlers take care to shut it up and enable the other. To avoid messages about "unbalanced interrupt enable/disable" they must not be automatically enabled when initally requested. This was not an issue with the db1200_defconfig due to fortunate timings; on a build without network chip support the warnings appear.

2010-04-30MIPS: Don't vmap things at address zero.David Daney
In the 64-bit kernel we use swapper_pg_dir for three different things. 1) xuseg mappings for kernel threads. 2) vmap mappings for all kernel-space accesses in xkseg. 3) vmap mappings for kernel modules in ksseg (kseg2). Due to how the TLB refill handlers work, any mapping established in xkseg or ksseg will also establish a xuseg mapping that should never be used by the kernel. In order to be able to use exceptions to trap NULL pointer dereferences, we need to ensure that nothing is mapped at address zero. Since vmap mappings in xkseg are reflected in xuseg, this means we need to ensure that there are no vmap mappings established at the start of xkseg. So we move back VMALLOC_START to avoid establishing vmap mappings at the start of xkseg.

2010-04-30x86: Fix 'reservetop=' functionalityLiang Li
When specifying the 'reservetop=0xbadc0de' kernel parameter, the kernel will stop booting due to a early_ioremap bug that relates to commit 8827247ff. The root cause of boot failure problem is the value of 'slot_virt[i]' was initialized in setup_arch->early_ioremap_init(). But later in setup_arch, the function 'parse_early_param' will modify 'FIXADDR_TOP' when 'reservetop=0xbadc0de' being specified. The simplest fix might be use __fix_to_virt(idx0) to get updated value of 'FIXADDR_TOP' in '__early_ioremap' instead of reference old value from slot_virt[slot] directly. Changelog since v0: -v1: When reservetop being handled then FIXADDR_TOP get adjusted, Hence check prev_map then re-initialize slot_virt and PMD based on new FIXADDR_TOP. -v2: place fixup_early_ioremap hence call early_ioremap_init in reserve_top_address to re-initialize slot_virt and corresponding PMD when parse_reservertop -v3: move fixup_early_ioremap out of reserve_top_address to make sure other clients of reserve_top_address like xen/lguest won't broken Signed-off-by: Liang Li <liang.li@windriver.com> Tested-by: Konrad Rzeszutek Wilk <konrad.wilk@oracle.com> Acked-by: Yinghai Lu <yinghai@kernel.org> Acked-by: Jeremy Fitzhardinge <jeremy.fitzhardinge@citrix.com> Cc: Wang Chen <wangchen@cn.fujitsu.com> Cc: "H.

The bypassing of this test is a leftover from 2.4 vintage kernels, and is no longer appropriate, or even used by KGDB. Currently KGDB uses probe_kernel_write() for all access to memory via the KGDB core, so it can simply be deleted. This fixes CVE-2010-1446.

2010-04-28x86/PCI: compute Address Space length rather than using _LENBjorn Helgaas
ACPI _CRS Address Space Descriptors have _MIN, _MAX, and _LEN. Linux has been computing Address Spaces as [_MIN to _MIN + _LEN - 1]. Based on the tests in the bug reports below, Windows apparently uses [_MIN to _MAX]. Per spec (ACPI 4.0, Table 6-40), for _CRS fixed-size, fixed location descriptors, "_LEN must be (_MAX - _MIN + 1)", and when that's true, it doesn't matter which way we compute the end. But of course, there are BIOSes that don't follow this rule, and we're better off if Linux handles those exceptions the same way as Windows. This patch makes Linux use [_MIN to _MAX], as Windows seems to do. This effectively reverts d558b483d5 and 03db42adfe and replaces them with simpler code. https://bugzilla.kernel.org/show_bug.cgi?id=14337 (round) https://bugzilla.kernel.org/show_bug.cgi?id=15480 (truncate) Signed-off-by: Bjorn Helgaas <bjorn.helgaas@hp.com> Signed-off-by: Jesse Barnes <jbarnes@virtuousgeek.org>

Firmware changed the way it represents memory and cpu affinity on POWER7. Unfortunately the old method now caps the topology to work around issues with legacy operating systems.

We set the form 1 field in the client architecture, and if we see "1" in the ibm,associativity-form property firmware supports form 1 affinity and we should look at the first field in the ibm,associativity-reference-points array.

2010-04-24VMware Balloon driverDmitry Torokhov
This is a standalone version of VMware Balloon driver. Ballooning is a technique that allows hypervisor dynamically limit the amount of memory available to the guest (with guest cooperation). In the overcommit scenario, when hypervisor set detects that it needs to shuffle some memory, it instructs the driver to allocate certain number of pages, and the underlying memory gets returned to the hypervisor. Later hypervisor may return memory to the guest by reattaching memory to the pageframes and instructing the driver to "deflate" balloon. We are submitting a standalone driver because KVM maintainer (Avi Kivity) expressed opinion (rightly) that our transport does not fit well into virtqueue paradigm and thus it does not make much sense to integrate with virtio. There were also some concerns whether current ballooning technique is the right thing. If there appears a better framework to achieve this we are prepared to evaluate and switch to using it, but in the meantime we'd like to get this driver upstream. We want to get the driver accepted in distributions so that users do not have to deal with an out-of-tree module and many distributions have "upstream first" requirement. The driver has been shipping for a number of years and users running on VMware platform will have it installed as part of VMware Tools even if it will not come from a distribution, thus there should not be additional risk in pulling the driver into mainline. The driver will only activate if host is VMware so everyone else should not be affected at all.

2010-04-23x86: Disable large pages on CPUs with Atom erratum AAE44H. Peter Anvin
Atom erratum AAE44/AAF40/AAG38/AAH41: "If software clears the PS (page size) bit in a present PDE (page directory entry), that will cause linear addresses mapped through this PDE to use 4-KByte pages instead of using a large page after old TLB entries are invalidated. Due to this erratum, if a code fetch uses this PDE before the TLB entry for the large page is invalidated then it may fetch from a different physical address than specified by either the old large page translation or the new 4-KByte page translation. This erratum may also cause speculative code fetches from incorrect addresses." [http://download.intel.com/design/processor/specupdt/319536.pdf] Where as commit 211b3d03c7400f48a781977a50104c9d12f4e229 seems to workaround errata AAH41 (mixed 4K TLBs) it reduces the window of opportunity for the bug to occur and does not totally remove it. This patch disables mixed 4K/4MB page tables totally avoiding the page splitting and not tripping this processor issue. This is based on an original patch by Colin King.

2010-04-23x86-64: Clear a 64-bit FS/GS base on fork if selector is nonzeroH. Peter Anvin
When we do a thread switch, we clear the outgoing FS/GS base if the corresponding selector is nonzero. This is taken by __switch_to() as an entry invariant; it does not verify that it is true on entry. However, copy_thread() doesn't enforce this constraint, which can result in inconsistent results after fork(). Make copy_thread() match the behavior of __switch_to().
