Implement arch_klp_init_object_loaded() for x86, which applies alternatives/paravirt patches. This fixes the order in which relocations and alternatives/paravirt patches are applied. Previously, if a patch module had alternatives or paravirt patches, these were applied first by the module loader

[PATCH v3 0/3] USB Audio Gadget refactoring

I came to this patch series when wanted to do two things: - use UAC1 as virtual ALSA sound card on gadget side, just like UAC2 is used so it's possible to do rate resampling - have both playback/capture support in UAC1 Since I wanted to have same behavior for both UAC1/UAC2, obviously

This patch adds new function f_uac1_newapi that uses recently created u_audio api. This makes f_uac1_newapi implementation much simpler by reusing existing u_audio core utilities. This also drops previous f_uac1 approach (write audio samples directly to existing ALSA sound card) and moves to more

[PATCH 03/18] arm64: ensure the kernel is compiled for LP64

From: Andrew Pinski The kernel needs to be compiled as a LP64 binary for ARM64, even when using a compiler that defaults to code-generation for the ILP32 ABI. Consequently, we need to explicitly pass '-mabi=lp64' (supported on gcc-4.9 and newer). Signed-off-by: Andrew Pinski
