2014-02-05arm64: Invalidate the TLB when replacing pmd entries during bootCatalin Marinas1-2/+10
With the 64K page size configuration, __create_page_tables in head.S maps enough memory to get started but using 64K pages rather than 512M sections with a single pgd/pud/pmd entry pointing to a pte table. create_mapping() may override the pgd/pud/pmd table entry with a block (section) one if the RAM size is more than 512MB and aligned correctly. For the end of this block to be accessible, the old TLB entry must be invalidated.

Add DSB after icache flush to complete the cache maintenance operation. The function __flush_icache_all() is used only for user space mappings and an ISB is not required because of an exception return before executing user instructions.

AD1983 has flexible loopback routes and the generic parser would take wrong path confusingly instead of taking individual paths via NID 0x0c and 0x0d. For avoiding it, limit the connections at these widgets so that the parser can think more straightforwardly. This fixes the regression of the missing line-in loopback on Dell machine.

2014-02-05drm/vmwgfx: Reemit context bindings when necessary v2Thomas Hellstrom6-28/+222
When a context is first referenced in the command stream, make sure that all scrubbed (as a result of eviction) bindings are re-emitted. Also make sure that all bound resources are put on the resource validate list. This is needed for legacy emulation, since legacy user-space drivers will typically not re-emit shader bindings. It also removes the requirement for user-space drivers to re-emit render-target- and texture bindings. Makes suspend and hibernate now also work with legacy user-space drivers on guest-backed devices. v2: Don't rebind on legacy devices.

2014-02-04kbuild: don't enable DEBUG_INFO when building for COMPILE_TESTLinus Torvalds1-1/+1
It really isn't very interesting to have DEBUG_INFO when doing compile coverage stuff (you wouldn't want to run the result anyway, that's kind of the whole point of COMPILE_TEST), and it currently makes the build take longer and use much more disk space for "all{yes,mod}config". There's somewhat active discussion about this still, and we might end up with some new config option for things like this (Andi points out that the silly X86_DECODER_SELFTEST option also slows down the normal coverage tests hugely), but I'm starting the ball rolling with this simple one-liner. DEBUG_INFO isn't that noticeable if you have tons of memory and a good IO subsystem, but it hurts you a lot if you don't - for very little upside for the common use.

2014-02-04arm64: vdso: prevent ld from aligning PT_LOAD segments to 64kWill Deacon1-1/+1
Whilst the text segment for our VDSO is marked as PT_LOAD in the ELF headers, it is mapped by the kernel and not actually subject to demand-paging. ld doesn't realise this, and emits a p_align field of 64k (the maximum supported page size), which conflicts with the load address picked by the kernel on 4k systems, which will be 4k aligned. This causes GDB to fail with "Failed to read a valid object file image from memory" when attempting to load the VDSO. This patch passes the -n option to ld, which prevents it from aligning PT_LOAD segments to the maximum page size.

2014-02-04[media] Revert "[media] videobuf_vm_{open,close} race fixes"Hans Verkuil3-19/+13
This reverts commit a242f426108c284049a69710f871cc9f11b13e61. That commit actually caused deadlocks, rather then fixing them. If ext_lock is set to NULL (otherwise videobuf_queue_lock doesn't do anything), then you get this deadlock: The driver's mmap function calls videobuf_mmap_mapper which calls videobuf_queue_lock on q. videobuf_mmap_mapper calls __videobuf_mmap_mapper, __videobuf_mmap_mapper calls videobuf_vm_open and videobuf_vm_open calls videobuf_queue_lock on q (introduced by above patch): deadlocked. This affects drivers using dma-contig and dma-vmalloc. Only dma-sg is not affected since it doesn't call videobuf_vm_open from __videobuf_mmap_mapper. Most drivers these days have a non-NULL ext_lock. Those that still use NULL there are all fairly obscure drivers, which is why this hasn't been seen earlier. Since everything worked perfectly fine for many years I prefer to just revert this patch rather than trying to fix it. videobuf is quite fragile and I rather not touch it too much. Work is (slowly) progressing to move everything over to vb2 or at the very least use non-NULL ext_lock in videobuf.
