    x86/efi: Rip out phys_efi_get_time() · 3f4a7836
    Matt Fleming 提交于
    Dan reported that phys_efi_get_time() is doing kmalloc(..., GFP_KERNEL)
    under a spinlock which is very clearly a bug. Since phys_efi_get_time()
    has no users let's just delete it instead of trying to fix it.
    
    Note that since there are no users of phys_efi_get_time(), it is not
    possible to actually trigger a GFP_KERNEL alloc under the spinlock.
