Convert a nonnegative error return code to a negative one, as returned elsewhere in the function. A simplified version of the semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> ( if@p1 (\(ret < 0\|ret != 0\)) { ... return ret; } | ret@p1 = 0 ) ... when != ret = e1 when != &ret *if(...) { ... when != ret = e2 when forall return ret; } // </smpl> Signed-off-by: Peter Senna Tschudin <peter.senna@gmail.com> [laurent.pinchart@ideasonboard.com Replaced EBUSY with ENODEV] Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

2012-09-27x86/mce: Provide boot argument to honour bios-set CMCI thresholdNaveen N. Rao
The ACPI spec doesn't provide for a way for the bios to pass down recommended thresholds to the OS on a _per-bank_ basis. This patch adds a new boot option, which if passed, tells Linux to use CMCI thresholds set by the bios. As fail-safe, we initialize threshold to 1 if some banks have not been initialized by the bios and warn the user. Signed-off-by: Naveen N.

Correct a direct dereference of I/O memory to use an appropriate I/O memory access function. Note that the pointer being dereferenced is not currently tagged with `__iomem` but I plan to correct that for 3.7.

2012-09-27x86, smep, smap: Make the switching functions one-wayH. Peter Anvin
There is no fundamental reason why we should switch SMEP and SMAP on during early cpu initialization just to switch them off again. Now with %eflags and %cr4 forced to be initialized to a clean state, we only need the one-way enable. Also, make the functions inline to make them (somewhat) harder to abuse. This does mean that SMEP and SMAP do not get initialized anywhere near as early. Even using early_param() instead of __setup() doesn't give us control early enough to do this during the early cpu initialization phase. This seems reasonable to me, because SMEP and SMAP should not matter until we have userspace to protect ourselves from, but it does potentially make it possible for a bug involving a "leak of permissions to userspace" to get uncaught.

Recent changes (KVM: make processes waiting on vcpu mutex killable) now requires to check the return value of vcpu_load. This triggered a warning in s390 specific kvm code. Turns out that we can actually remove the put/load, since schedule will do the right thing via the preempt notifiers.

2012-09-27USB: Fix race condition when removing host controllersAlan Stern
This patch (as1607) fixes a race that can occur if a USB host controller is removed while a process is reading the /sys/kernel/debug/usb/devices file. The usb_device_read() routine uses the bus->root_hub pointer to determine whether or not the root hub is registered. The is not a valid test, because the pointer is set before the root hub gets registered and remains set even after the root hub is unregistered and deallocated. As a result, usb_device_read() or usb_device_dump() can access freed memory, causing an oops. The patch changes the test to use the hcd->rh_registered flag, which does get set and cleared at the appropriate times. It also makes sure to hold the usb_bus_list_lock mutex while setting the flag, so that usb_device_read() will become aware of new root hubs as soon as they are registered.

2012-09-27drm/radeon: add 2-level VM pagetables support v9Dmitry Cherkasov
PDE/PTE update code uses CP ring for memory writes. All page table entries are preallocated for now in alloc_pt(). It is made as whole because it's hard to divide it to several patches that compile and doesn't break anything being applied separately. Tested on cayman card. v2: rebased on top of "refactor set_page chipset interface v3", code cleanups v3: switched offsets calc macros to inline funcs where possible, remove pd_addr from radeon_vm, switched RADEON_BLOCK_SIZE define, to 9 (and PTE_COUNT to 1 << BLOCK_SIZE) v4 (ck): move "incr" documentation to previous patch, cleanup and document RADEON_VM_* constants, change commit message to our usual format, simplify patch allot by removing everything current not necessary, disable SI workaround. v5: (agd5f): Fix typo in tables_size calculation in radeon_vm_alloc_pt(). Second line should have been '+=' rather than '='. v6: fix npdes calculation. In scenario when pfns to be mapped overlap two PDE spans: +-----------+-------------+ | PDE span | PDE span | +-----------+----+--------+ | | +---------+ | pfns | +---------+ the following npdes calculation gives incorrect result: npdes = (nptes >> RADEON_VM_BLOCK_SIZE) + 1; For the case above picture it should give npdes = 2, but gives one. This patch corrects it by rounding last pfn up to 512 border, first - down to 512 border and then subtracting and dividing by 512. v7: Make npde calculation clearer, fix ndw calculation. v8: (agd5f): reserve enough for 2 full VM PTs, add some additional comments. v9: fix typo in npde calculation Signed-off-by: Dmitry Cherkasov <Dmitrii.Cherkasov@amd.com> Signed-off-by: Christian König <deathsimple@vodafone.de> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>

2012-09-27drm/radeon: work around KMS modeset limitations in PLL allocation (v2)Alex Deucher
Since the current KMS API sets the mode independantly on each crtc, we may end up with resource conflicts. The PLL allocation is one of those cases. In the following example we have 3 crtcs in use driving 2 DVI connectors and 1 DP connector. On the initial kernel modeset for fbdev, the display topology ends up as follows: crtc0 -> DP-0 crtc1 -> DVI-0 crtc2 -> DVI-1 Because this is the first modeset, all of the PLLs are available as none have been assigned. So we end up with the following: crtc0 uses DCPLL crtc1 uses PPLL2 crtc2 uses PPLL1 When X starts, it assigns a different topology: crtc0 -> DVI-0 crtc1 -> DP-0 crtc2 -> DVI-1 However, since the KMS API is per crtc, we set the mode on each crtc independantly. When it comes time to set the mode on crtc0, the topology for crtc1 and crtc2 are still intact. crtc1 and crtc2 are already assigned PPLL2 and PPLL1 so when it comes time to set the mode on crtc0, crtc1 and crtc2 have not been torn down yet, so there appears to be no PLLs available. In reality, we are reconfiguring the entire display topology, however, since each crtc is handled independantly, we don't know that in the driver at each crtc mode set time. This patch checks to see if the same connector is being driven by another crtc, and if so, uses the PLL already associated with it. v2: store connector in the radeon crtc struct, simplify checking.
