2014-08-20drm/i915/bdw: Don't write PDP in the legacy way when using LRCsOscar Mateo1-0/+6
This is mostly for correctness so that we know we are running the LR context correctly (this is, the PDPs are contained inside the context object). v2: Move the check to inside the enable PPGTT function. The switch happens in two places: the legacy context switch (that we won't hit when Execlists are enabled) and the PPGTT enable, which unfortunately we need. This would look much nicer if the ppgtt->enable was part of the ring init, where it logically belongs. v3: Move the check to the start of the enable PPGTT function. None of the legacy PPGTT enabling is required when using LRCs as the PPGTT is enabled in the context descriptor and the PDPs are written in the LRC. v4: Clarify comment based on review feedback.

2014-08-20perf: Handle compat ioctlPawel Moll1-1/+22
When running a 32-bit userspace on a 64-bit kernel (eg. i386 application on x86_64 kernel or 32-bit arm userspace on arm64 kernel) some of the perf ioctls must be treated with special care, as they have a pointer size encoded in the command. For example, PERF_EVENT_IOC_ID in 32-bit world will be encoded as 0x80042407, but 64-bit kernel will expect 0x80082407. In result the ioctl will fail returning -ENOTTY. This patch solves the problem by adding code fixing up the size as compat_ioctl file operation.

2014-08-19arm64: align randomized TEXT_OFFSET on 4 kB boundaryArd Biesheuvel2-5/+5
When booting via UEFI, the kernel Image is loaded at a 4 kB boundary and the embedded EFI stub is executed in place. The EFI stub relocates the Image to reside TEXT_OFFSET bytes above a 2 MB boundary, and jumps into the kernel proper. In AArch64, PC relative symbol references are emitted using adrp/add or adrp/ldr pairs, where the offset into a 4 kB page is resolved using a separate :lo12: relocation. This implicitly assumes that the code will always be executed at the same relative offset with respect to a 4 kB boundary, or the references will point to the wrong address. This means we should link the kernel at a 4 kB aligned base address in order to remain compatible with the base address the UEFI loader uses when doing the initial load of Image. So update the code that generates TEXT_OFFSET to choose a multiple of 4 kB. At the same time, update the code so it chooses from the interval [0..2MB) as the author originally intended.

We did not check relocated directory in any way when processing Rock Ridge 'CL' tag. Thus a corrupted isofs image can possibly have a CL entry pointing to another CL entry leading to possibly unbounded recursion in kernel code and thus stack overflow or deadlocks (if there is a loop created from CL entries). Fix the problem by not allowing CL entry to point to a directory entry with CL entry (such use makes no good sense anyway) and by checking whether CL entry doesn't point to itself.

2014-08-19MIPS: NL: Fix nlm_xlp_defconfig build errorGuenter Roeck1-7/+0
The nlm_xlp_defconfig build fails with ./arch/mips/include/asm/mach-netlogic/topology.h:15:0: error: "topology_core_id" redefined [-Werror] In file included from include/linux/smp.h:59:0, [ ...] from arch/mips/mm/dma-default.c:12: ./arch/mips/include/asm/smp.h:41:0: note: this is the location of the previous definition and similar errors. This is caused by commit bda4584cd943d7 ("MIPS: Support CPU topology files in sysfs") which adds the defines to arch/mips/include/asm/smp.h. Remove the defines from arch/mips/include/asm/mach-netlogic/topology.h as no longer necessary.

Now that the PFP and ME synchronization is fixed, we can enable this again reliably. Signed-off-by: Alex Deucher <[email protected]> Tested-by: Michel Dänzer <[email protected]>
2014-08-19drm/radeon: Sync ME and PFP after CP semaphore waits v4Christian König3-0/+36
Fixes lockups due to CP read GPUVM faults when running piglit on Cape Verde. v2 (chk): apply the fix to R600+ as well, on CIK only the GFX CP has a PFP, add more comments to R600 code, enable flushing again v3: (agd5f): only apply to 7xx+. r6xx does not have the packet. v4: (agd5f): split flush change into a separate patch, fix formatting Signed-off-by: Michel Dänzer <[email protected]> Signed-off-by: Christian König <[email protected]> Signed-off-by: Alex Deucher <[email protected]> Tested-by: Michel Dänzer <[email protected]>

2014-08-19drm/radeon: fix display handling in radeon_gpu_resetAlex Deucher1-0/+16
If the display hw was reset or a hard reset was used, we need to re-init some of the common display hardware as well. Signed-off-by: Alex Deucher <[email protected]> Cc: [email protected]
2014-08-19drm/radeon: fix pm handling in radeon_gpu_resetAlex Deucher1-2/+16
pm_suspend is handled in the radeon_suspend callbacks. pm_resume has special handling depending on whether dpm or legacy pm is enabled. Change radeon_gpu_reset to mirror the behavior in the suspend and resume pathes. Signed-off-by: Alex Deucher <[email protected]> Reviewed-by: Christian König <[email protected]> Cc: [email protected]

2014-08-19i2c: rework kernel config I2C_ACPILan Tianyu4-14/+17
Commit da3c6647(I2C/ACPI: Clean up I2C ACPI code and Add CONFIG_I2C_ACPI config) adds a new kernel config I2C_ACPI and make I2C core built in when the config is selected. This is wrong because distributions etc generally compile I2C as a module and the commit broken that. This patch is to rename I2C_ACPI to ACPI_I2C_OPREGION. New config only controls ACPI I2C operation region code and depends on I2C=y.
