The comments in the ASID allocator incorrectly hint at an MP-style idiom using the asid_generation and the active_asids array. In fact, the synchronisation is achieved using a combination of an xchg operation and a spinlock, so update the comments and remove the pointless smp_wmb().

Dave Martin authored
The fpsimd_update_current_state() function is responsible for loading the FPSIMD state from the user signal frame into the current task during sigreturn. When implementing support for SVE, conditional code was added to this function in order to handle the case where SVE state need to be loaded for the task and merged with the FPSIMD data from the signal frame; however, the FPSIMD-only case was unintentionally dropped. As a result of this, sigreturn does not currently restore the FPSIMD state of the task, except in the case where the system supports SVE and the signal frame contains SVE state in addition to FPSIMD state. This patch fixes this bug by making the copy-in of the FPSIMD data from the signal frame to thread_struct unconditional. This remains a performance regression from v4.14, since the FPSIMD state is now copied into thread_struct and then loaded back, instead of _only_ being loaded into the CPU FPSIMD registers. However, it is essential to call task_fpsimd_load() here anyway in order to ensure that the SVE enable bit in CPACR_EL1 is set correctly before returning to userspace. This could use some refactoring, but since sigreturn is not a fast path I have kept this patch as a pure fix and left the refactoring for later.

When building the arm64 kernel with both CONFIG_ARM64_MODULE_PLTS and CONFIG_DYNAMIC_FTRACE enabled, the ftrace-mod.o object file is built with the kernel and contains a trampoline that is linked into each module, so that modules can be loaded far away from the kernel and still reach the ftrace entry point in the core kernel with an ordinary relative branch, as is emitted by the compiler instrumentation code dynamic ftrace relies on. In order to be able to build out of tree modules, this object file needs to be included into the linux-headers or linux-devel packages, which is undesirable, as it makes arm64 a special case (although a precedent does exist for 32-bit PPC). Given that the trampoline essentially consists of a PLT entry, let's not bother with a source or object file for it, and simply patch it in whenever the trampoline is being populated, using the existing PLT support routines.

When an AFS inode is allocated by afs_alloc_inode(), the allocated afs_vnode struct isn't necessarily reset from the last time it was used as an inode because the slab constructor is only invoked once when the memory is obtained from the page allocator. This means that information can leak from one inode to the next because we're not calling kmem_cache_zalloc(). Some of the information isn't reset, in particular the permit cache pointer. Bring the clearances up to date. Signed-off-by: David Howells <dhowells@redhat.com> Tested-by: Marc Dionne <marc.dionne@auristor.com>

Fix four refcount bugs in afs_cache_permit(): (1) When checking the result of the kzalloc(), we can't just return, but must put 'permits'. (2) We shouldn't put permits immediately after hashing a new permit as we need to keep the pointer stable so that we can check to see if vnode->permit_cache has changed before we decide whether to assign to it. (3) 'permits' is being put twice. (4) We need to put either the replacement or the thing replaced after the assignment to vnode->permit_cache. Without this, lots of the following are seen: Kernel BUG at ffffffffa039857b [verbose debug info unavailable] ------------[ cut here ]------------ Kernel BUG at ffffffffa039858a [verbose debug info unavailable] ------------[ cut here ]------------ The addresses are in the .text..refcount section of the kafs.ko module. Following the relocation records for the __ex_table section shows one to be due to the decrement in afs_put_permits() and the other to be key_get() in afs_cache_permit(). Occasionally, the following is seen: refcount_t overflow at afs_cache_permit+0x57d/0x5c0 [kafs] in cc1[562], uid/euid: 0/0 WARNING: CPU: 0 PID: 562 at kernel/panic.c:657 refcount_error_report+0x9c/0xac ...

drm_atomic_helper_wait_for_vblanks will go away in the future. The new drm_atomic_helper_setup_commit in 4.15 expects that blocking commits have completed flipping before the commit_tail returns. This must be ensured by calling wait_for_vblanks or wait_for_flip_done, where flip_done might do a less agressive wait, which is fine for imx-drm.

Commit d178e034 ("drm: omapdrm: Move FEAT_DPI_USES_VDDS_DSI feature to dpi code") replaced usage of platform data version with SoC matching to configure DPI VDDS. The SoC match entries were incorrect, they should have matched on the machine name instead of the SoC family. Fix it. The result was observed on OpenPandora with OMAP3530 where the panel only had the Blue channel and Red&Green were missing. It was not observed on GTA04 with DM3730.

I believe the intention of the commit 2c9fc9bf ("drm: omapdrm: Move FEAT_HDMI_* features to hdmi4 driver") was to identify omap4430 ES1.x, omap4430 ES2.x and other OMAP4 revisions, like omap4460. By using family=OMAP4 in the match the code will treat omap4460 ES1.x in a same way as it would treat omap4430 ES1.x This breaks HDMI audio on OMAP4460 devices (PandaES for example). Correct the match rule so we are not going to get false positive match.

The new backlight code causes a link failure when backlight support itself is disabled: drivers/gpu/drm/omapdrm/displays/panel-dpi.o: In function `panel_dpi_probe_of': panel-dpi.c:(.text+0x35c): undefined reference to `of_find_backlight_by_node' This adds a Kconfig dependency like we have for the other OMAP display targets.

We seem to be missing some W/A for 2M pages and are getting a hit on raw GPU read bandwidths (even 30%) even though the GPU write bandwidths improve (even 10%).
