- Prevent KASLR from mapping the top page of the virtual address space
 
 - Fix device-tree probing of SDEI driver
 
 - Fix incorrect register offset definition in Hisilicon DDRC PMU driver
 
 - Fix compilation issue with older binutils not liking unsigned immediates
 
 - Fix uapi headers so that libc can provide its own sigcontext definition
 
 - Fix handling of private compat syscalls
 
 - Hook up compat io_pgetevents() syscall for 32-bit tasks
