2009-02-24netxen: fix physical port mappingDhananjay Phadke
The PCI function to physical port mapping is valid only for old firmware. New firmware (4.0.0+) abstracts this. So driver should never try to access phy using invalid mapping. The behavior is unpredictable when PCI functions 4-7 are enabled on the same NIC. Signed-off-by: Dhananjay Phadke <dhananjay@netxen.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2009-02-24x86: add remapping percpu first chunk allocatorTejun Heo
Impact: add better first percpu allocation for NUMA On NUMA, embedding allocator can't be used as different units can't be made to fall in the correct NUMA nodes. To use large page mapping, each unit needs to be remapped. However, percpu areas are usually much smaller than large page size and unused space hurts a lot as the number of cpus grow. This allocator remaps large pages for each chunk but gives back unused part to the bootmem allocator making the large pages mapped twice. This adds slightly to the TLB pressure but is much better than using 4k mappings while still being NUMA-friendly. Ingo suggested that this would be the correct approach for NUMA.

2009-02-24x86: add embedding percpu first chunk allocatorTejun Heo
Impact: add better first percpu allocation for !NUMA On !NUMA, we can simply allocate contiguous memory and use it for the first chunk without mapping it into vmalloc area. As the memory area is covered by the large page physical memory mapping, it allows the dynamic perpcu allocator to not add any TLB overhead for the static percpu area and whatever falls into the first chunk and the implementation is very simple too. Signed-off-by: Tejun Heo <tj@kernel.org>
2009-02-24x86: separate out setup_pcpu_4k() from setup_per_cpu_areas()Tejun Heo
Impact: modularize percpu first chunk allocation x86 is gonna have a few different strategies for the first chunk allocation. Modularize it by separating out the current allocation mechanism into pcpu_alloc_bootmem() and setup_pcpu_4k(). Signed-off-by: Tejun Heo <tj@kernel.org>
2009-02-24percpu: give more latitude to arch specific first chunk initializationTejun Heo
Impact: more latitude for first percpu chunk allocation The first percpu chunk serves the kernel static percpu area and may or may not contain extra room for further dynamic allocation. Initialization of the first chunk needs to be done before normal memory allocation service is up, so it has its own init path - pcpu_setup_static(). It seems archs need more latitude while initializing the first chunk for example to take advantage of large page mapping. This patch makes the following changes to allow this. * Define PERCPU_DYNAMIC_RESERVE to give arch hint about how much space to reserve in the first chunk for further dynamic allocation. * Rename pcpu_setup_static() to pcpu_setup_first_chunk(). * Make pcpu_setup_first_chunk() much more flexible by fetching page pointer by callback and adding optional @unit_size, @free_size and @base_addr arguments which allow archs to selectively part of chunk initialization to their likings. Signed-off-by: Tejun Heo <tj@kernel.org>
2009-02-24percpu: remove unit_size power-of-2 restrictionTejun Heo
Impact: allow unit_size to be arbitrary multiple of PAGE_SIZE In dynamic percpu allocator, there is no reason the unit size should be power of two. Remove the restriction. As non-power-of-two unit size means that empty chunks fall into the same slot index as lightly occupied chunks which is bad for reclaming. Reserve an extra slot for empty chunks. Signed-off-by: Tejun Heo <tj@kernel.org>
2009-02-24x86: update populate_extra_pte() and add populate_extra_pmd()Tejun Heo
Impact: minor change to populate_extra_pte() and addition of pmd flavor Update populate_extra_pte() to return pointer to the pte_t for the specified address and add populate_extra_pmd() which only populates till the pmd and returns pointer to the pmd entry for the address. For 64bit, pud/pmd/pte fill functions are separated out from set_pte_vaddr[_pud]() and used for set_pte_vaddr[_pud]() and populate_extra_{pte|pmd}(). Signed-off-by: Tejun Heo <tj@kernel.org>
2009-02-24vmalloc: add @align to vm_area_register_early()Tejun Heo
Impact: allow larger alignment for early vmalloc area allocation Some early vmalloc users might want larger alignment, for example, for custom large page mapping. Add @align to vm_area_register_early(). While at it, drop docbook comment on non-existent @size.

2009-02-24bootmem: reorder interface functions and add a missing oneTejun Heo
Impact: cleanup and addition of missing interface wrapper The interface functions in bootmem.h was ordered in not so orderly manner. Reorder them such that * functions allocating the same area group together - ie. alloc_bootmem group and alloc_bootmem_low group. * functions w/o node parameter come before the ones w/ node parameter. * nopanic variants are immediately below their panicky counterparts. While at it, add alloc_bootmem_pages_node_nopanic() which was missing. Signed-off-by: Tejun Heo <tj@kernel.org> Cc: Johannes Weiner <hannes@saeurebad.de>
2009-02-24bootmem: clean up arch-specific bootmem wrappingTejun Heo
Impact: cleaner and consistent bootmem wrapping By setting CONFIG_HAVE_ARCH_BOOTMEM_NODE, archs can define arch-specific wrappers for bootmem allocation. However, this is done a bit strangely in that only the high level convenience macros can be changed while lower level, but still exported, interface functions can't be wrapped. This not only is messy but also leads to strange situation where alloc_bootmem() does what the arch wants it to do but the equivalent __alloc_bootmem() call doesn't although they should be able to be used interchangeably. This patch updates bootmem such that archs can override / wrap the backend function - alloc_bootmem_core() instead of the highlevel interface functions to allow simpler and consistent wrapping. Also, HAVE_ARCH_BOOTMEM_NODE is renamed to HAVE_ARCH_BOOTMEM. Signed-off-by: Tejun Heo <tj@kernel.org> Cc: Johannes Weiner <hannes@saeurebad.de>
2009-02-24percpu: fix pcpu_chunk_struct_sizeTejun Heo

2009-02-23proc: proc_get_inode should de_put when inode already initializedKrzysztof Sachanowicz
de_get is called before every proc_get_inode, but corresponding de_put is called only when dropping last reference to an inode. This might cause something like remove_proc_entry: /proc/stats busy, count=14496 to be printed to the syslog. The fix is to call de_put in case of an already initialized inode in proc_get_inode.

2009-02-23x86: minor cleanup in the espfix codeStas Sergeev
Impact: Cleanup Checkin be44d2aabce2d62f72d5751d1871b6212bf7a1c7 eliminates the use of a 16-bit stack for espfix. However, at least one instruction remained that only operated on the low 16 bits of %esp. This is not a bug per se because the kernel stack is always an aligned 4K or 8K block. Therefore it cannot cross 64K boundaries; this code, in fact, relies strictly on that fact. However, it's a lot cleaner (and, for that matter, smaller) to operate on the entire 32-bit register.

2009-02-23drm/i915: suspend/resume GEM when KMS is activeJesse Barnes
In the KMS case, we need to suspend/resume GEM as well. So on suspend, make sure we idle GEM and stop any new rendering from coming in, and on resume, re-init the framebuffer and clear the suspended flag.

2009-02-23drm/i915: Don't let a device flush to prepare buffers clear new write_domains.Eric Anholt
The problem was that object_set_to_gpu_domain would set the new write_domains that are getting set by this batchbuffer, then the accumulated flushes required for all the objects in preparation for this batchbuffer were posted, and the brand new write domain would get cleared by the flush being posted. Instead, hang on to the new (or old if we're not changing it) value and set it after the flush is queued. Results from this noticably included conformance test failures from reads shortly after writes (where the new write domain had been lost and thus not flushed and waited on), but is a suspected cause of hangs in some apps when a write domain is lost on a buffer that gets reused for instruction or commmand state.

2009-02-23drm/i915: Cut two args to set_to_gpu_domain that confused this tricky path.Eric Anholt
While not strictly required, it helped while thinking about the following change. This change should be invariant. Signed-off-by: Eric Anholt <eric@anholt.net> Signed-off-by: Dave Airlie <airlied@redhat.com>

2009-02-23x86: refactor x86_quirks supportIngo Molnar
Impact: cleanup Make x86_quirks support more transparent. The highlevel methods are now named: extern void x86_quirk_pre_intr_init(void); extern void x86_quirk_intr_init(void); extern void x86_quirk_trap_init(void); extern void x86_quirk_pre_time_init(void); extern void x86_quirk_time_init(void); This makes it clear that if some platform extension has to do something here that it is considered ... weird, and is discouraged. Also remove arch_hooks.h and move it into setup.h (and other header files where appropriate). Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-02-23x86: remove various unused subarch hooksIngo Molnar
Impact: remove dead code Remove: - pre_setup_arch_hook() - mca_nmi_hook() If needed they can be added back via an x86_quirk handler. Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-02-23x86: remove the Voyager 32-bit subarchIngo Molnar
Impact: remove unused/broken code The Voyager subarch last built successfully on the v2.6.26 kernel and has been stale since then and does not build on the v2.6.27, v2.6.28 and v2.6.29-rc5 kernels. No actual users beyond the maintainer reported this breakage. Patches were sent and most of the fixes were accepted but the discussion around how to do a few remaining issues cleanly fizzled out with no resolution and the code remained broken. In the v2.6.30 x86 tree development cycle 32-bit subarch support has been reworked and removed - and the Voyager code, beyond the build problems already known, needs serious and significant changes and probably a rewrite to support it. CONFIG_X86_VOYAGER has been marked BROKEN then. The maintainer has been notified but no patches have been sent so far to fix it. While all other subarchs have been converted to the new scheme, voyager is still broken. We'd prefer to receive patches which clean up the current situation in a constructive way, but even in case of removal there is no obstacle to add that support back after the issues have been sorted out in a mutually acceptable fashion. So remove this inactive code for now. Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-02-23selinux: Fix the NetLabel glue code for setsockopt()Paul Moore
At some point we (okay, I) managed to break the ability for users to use the setsockopt() syscall to set IPv4 options when NetLabel was not active on the socket in question. The problem was noticed by someone trying to use the "-R" (record route) option of ping: # ping -R 10.0.0.1 ping: record route: No message of desired type The solution is relatively simple, we catch the unlabeled socket case and clear the error code, allowing the operation to succeed. Please note that we still deny users the ability to override IPv4 options on socket's which have NetLabel labeling active; this is done to ensure the labeling remains intact.
