reset_counter marks the reset counter number once the context is created, shouldn't be changed due to query. To keep U/K interface on the ctx_query and keep ctx's reset_counter logic compatible with GPU RESET feature, now use another var named "reset_counter_query" to replace the original checked & updated in amdgpu_ctx_query.

Bug: Kfifo is limited at size, during GPU reset it would fill up to limit and the pushing thread (producer) would wait for the scheduler worker to consume the items in the fifo while holding reservation lock on a BO. The gpu reset thread on the other hand blocks the scheduler during reset. Before it unblocks the sceduler it might want to recover VRAM and so will try to reserve the same BO the producer thread is already holding creating a deadlock. Fix: Switch from kfifo to SPSC queue which is unlimited in size.

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.
