MS		 73
74 On signal delivery, the kernel will create a signal handler stack
75 frame and setup the return address in LR to point at restorer stub.
76 The signal stack frame is defined by:
77
78 struct rt_sigframe
79 {
80 siginfo_t info;
81 struct ucontext uc;
82 };
83
1ae3db19
MS		 84 The ucontext has the following form:
85 struct ucontext
86 {
87 unsigned long uc_flags;
88 struct ucontext *uc_link;
89 stack_t uc_stack;
90 sigset_t uc_sigmask;
91 struct sigcontext uc_mcontext;
92 };
93
1ae3db19
MS		 94 struct sigcontext
95 {
96 unsigned long fault_address;
97 unsigned long regs[31];
98 unsigned long sp; / * 31 * /
99 unsigned long pc; / * 32 * /
100 unsigned long pstate; / * 33 * /
101 __u8 __reserved[4096]
102 };
103
05c71722
AH		 104 The reserved space in sigcontext contains additional structures, each starting
105 with a aarch64_ctx, which specifies a unique identifier and the total size of
106 the structure. The final structure in reserved will start will a null
107 aarch64_ctx. The penultimate entry in reserved may be a extra_context which
108 then points to a further block of reserved space.
109
110 struct aarch64_ctx {
111 u32 magic;
112 u32 size;
113 };
114
1ae3db19
MS		 115 The restorer stub will always have the form:
116
117 d28015a8 movz x8, #0xad
118 d4000001 svc #0x0
119
f2205de0
HZ		 120 This is a system call sys_rt_sigreturn.
121
1ae3db19
MS		 122 We detect signal frames by snooping the return code for the restorer
123 instruction sequence.
124
125 The handler then needs to recover the saved register set from
126 ucontext.uc_mcontext. */
