Some x86 platforms like Intel MID platforms don't have i8042 controllers, and i8042 driver's probe to some legacy IO ports may hang the MID processor. With this hook, i8042 driver can runtime check and skip the probe when the pretection fail which also saves some probe time [ hpa note: this is currently a compile-time check, which breaks the i386 allyesconfig build. This patch series thus does fix a regression. ] Signed-off-by:

* 'drm-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/airlied/drm-2.6: drm: correctly update connector DPMS status in drm_fb_helper drm/radeon/kms: fix shared ddc handling drm/ttm: Allocate the page pool manager in the heap.

Jesse Barnes authored
We don't currently update the DPMS status of the connector (both in the connector itself and the connector's DPMS property) in the fb helper code. This means that if the kernel FB core has blanked the screen, sysfs will still show a DPMS status of "on". It also means that when X starts, it will try to light up the connectors, but the drm_crtc_helper code will ignore the DPMS change since according to the connector, the DPMS status is already on. Fixes https://bugs.freedesktop.org/show_bug.cgi?id=28436 (the annoying "my screen was blanked when I started X and now it won't light up" bug). Signed-off-by:

Repeated ttm_page_alloc_init/fini fails noisily because the pool manager kobj isn't zeroed out between uses (we could do just that but statically allocated kobjects are generally considered a bad thing). Move it to kzalloc'ed memory. Note that this patch drops the refcounting behavior of the pool allocator init/fini functions: it would have led to a race condition in its current form, and anyway it was never exploited. This fixes a regression with reloading kms modules at runtime, since page allocator was introduced. Signed-off-by:

This patch introduces 3 VFS accessors: 'sb_mark_dirty()', 'sb_mark_clean()', and 'sb_is_dirty()'. They simply set 'sb->s_dirt' or test 'sb->s_dirt'. The plan is to make every FS use these accessors later instead of manipulating the 'sb->s_dirt' flag directly. Ultimately, this change is a preparation for the periodic superblock synchronization optimization which is about preventing the "sync_supers" kernel thread from waking up even if there is nothing to synchronize. This patch does not do any functional change, just adds accessor functions. Signed-off-by:

When trying to netboot a Linksys WRT54GS WLAN router, the bootup fails, because of following error message: ... [ 0.424000] b44: b44.c:v2.0 [ 0.424000] b44: Invalid MAC address found in EEPROM [ 0.432000] b44 ssb0:1: Problem fetching invariants of chip,aborting [ 0.436000] b44: probe of ssb0:1 failed with error -22 ... The router uses a CFE bootloader, but most of the needed environment variables for network card initialization, are not available from CFE via printenv and even though not via cfe_getenv(). The required environment variables are saved in a special partition in flash memory. The attached patch implement nvram_getenv and enables bootup via NFS root on my router. Most of the patch is extracted from the OpenWrt subversion repository and stripped down and cleaned up to just fix this issue. [Ralf: sorted out header file inclusions. Lots of unneded headers and such that should have been included.] Signed-off-by:

This patch adds an inline function in_module() to check which space the instruction pointer in, kernel space or module space. Note: This will not work when the kernel space and module space are the same. If they are the same, we need to modify scripts/recordmcount.pl, ftrace_make_nop/call() and the other related parts to ensure the enabling/disabling of the calling site to _mcount is right for both kernel and module. [Ralf: It also is still incorrect for some 64-bit kernels.] Signed-off-by:

-
Wu Zhangjin authored
With the help of uasm this patch encodes the instructions of the dynamic function tracer in ftrace_dyn_arch_init() when initializing it. As a result we can remove the dynamic encoding of instructions in ftrace_make_nop()/call(), ftrace_enable_ftrace_graph_caller() and remove the macro jump_insn_encode() and at last this reduce the overhead of dynamic Function Tracer. This also is cleaner. Signed-off-by:

For 32-bit kernel the -mmcount-ra-address option of gcc 4.5 emits one extra instruction before calling to _mcount so we need to use a different "b 1f" for it. Signed-off-by:
-
Wu Zhangjin authored
As documented in the GCC 4.5 docs [1] -mmcount-ra-address uses register $12 to pass the stack offset of the return address to the _mcount function. On 64-bit kernels $12 is t0 but in 32-bit kernels it is t4 so we need to use $12 instead of t0 here to be correct for both kernel types.

Reimplement augmented RB-trees without sprinkling extra branches all over the RB-tree code (which lives in the scheduler hot path). This approach is 'borrowed' from Fabio's BFQ implementation and relies on traversing the rebalance path after the RB-tree-op to correct the heap property for insertion/removal and make up for the damage done by the tree rotations. For insertion the rebalance path is trivially that from the new node upwards to the root, for removal it is that from the deepest node in the path from the to be removed node that will still be around after the removal. [ This patch also fixes a video driver regression reported by Ali Gholami Rudi - the memtype->subtree_max_end was updated incorrectly. ] Acked-by:
