  "message": "arm64: mm: Set stack size from the kernel command line\n\nAllow changing the runtime stack size by passing the command line\nargument `kernel_thread_shift\u003d`. This allows the user to configure\nthe stack size down to the PAGE_SIZE to save memory. Note that memory\nwill be saved only for the newly created tasks.\n\nMemory is saved dynamically when a task is created. No memory changes\ntake effect at compile time.\nCONFIG_ARCH_HAS_VARIABLE_STACK_SIZE must be set to override the generic\nkernel_thread_shift, and this config does not affect the size of the\nstack itself.\n\nA lower bound on the kernel_thread_shift is placed at 13 corresponding\nto an 8K stack which is the minimum value for the stack to work on\narm64, an upper bound on kernel_thread_shift is placed at 14\ncorresponding to the default 16K stack size to make sure that the\nvmap_stack configuration does not try to get pages out of order.\n\nTesting on Android verified that the 8K stack size works and does not\nresult in a stack overflow.\n\nSigned-off-by: Mostafa Saleh \u003csmostafa@google.com\u003e\n",
