2021-02-22kexec: move machine_kexec_post_load() to public interfacePavel Tatashin
The kernel test robot reports the following compiler warning: | arch/arm64/kernel/machine_kexec.c:62:5: warning: no previous prototype for | function 'machine_kexec_post_load' [-Wmissing-prototypes] | int machine_kexec_post_load(struct kimage *kimage) Fix it by moving the declaration of machine_kexec_post_load() from kexec_internal.h to the public header instead.

2021-02-22drm/i915/gvt: Introduce per object locking in GVT scheduler.Zhi Wang
To support ww locking and per-object implemented in i915, GVT scheduler needs to be refined. Most of the changes are located in shadow batch buffer, shadow wa context in GVT-g, where use quite a lot of i915 gem object APIs. v2: - Adjust the usage of ww lock on context pin/unpin. (maarten) - Rebase the patch on the newest staging branch. Fixes: 6b05030496f7 ("drm/i915: Convert i915_gem_object/client_blt.c to use ww locking as well, v2.")

With the move away from kthread, we can also dump everything related to assigned state to the new threads. Signed-off-by: Jens Axboe <axboe@kernel.dk>

Most of architectures generate syscall headers at the compile time in a similar way. The syscall table has the same format for all architectures. Each line has up to 5 fields; syscall number, ABI, syscall name, native entry point, and compat entry point. The syscall table is processed by syscalltbl.sh script into header files. Despite the same pattern, scripts are maintained per architecture, which results in code duplication and bad maintainability.

2021-02-21n64: store dev instance into disk private dataChaitanya Kulkarni
The device instance is declared globally. Remove global variable & use the disk->private_data to store the device instance in the n64cart_probe() and get the same instance from bio->bi_disk->private data in n64cart_submit_bio.

2021-02-21n64: cleanup n64cart_probe()Chaitanya Kulkarni
The goto label fail_queue is needed to cleanup the queue allocation when devm_platform_ioremap_resource() or alloc_disk() fails, either of these two functions are not dependent on the queue variable which is allocated prior to these calls. Allocate the queue variable after successful alloc_disk(). Return error directly when devm_platform_ioremap_resource() or alloc_disk() fail. Remove fail_queue label and a call to the blk_cleanup_queue(). Direct return from these two functions allows us to remove the local variable err and allocating queue after alloc_disk() allows us to remove the local variable queue so we use disk->queue directly.

This adds support for the Nintendo 64 console's carts. Carts are a read-only media ranging from 8mb to 64mb. Only one cart can be connected at once, and switching it requires a reboot.
