173
- * Following are the BOOK3S exception handler helper macros.
174
- * Handlers come in a number of types, and each type has a number of varieties.
175
- *
176
- * EXC_REAL_*     - real, unrelocated exception vectors
177
- * EXC_VIRT_*     - virt (AIL), unrelocated exception vectors
178
- * TRAMP_REAL_*   - real, unrelocated helpers (virt can call these)
179
- * TRAMP_VIRT_*   - virt, unreloc helpers (in practice, real can use)
180
- * TRAMP_KVM      - KVM handlers that get put into real, unrelocated
181
- * EXC_COMMON     - virt, relocated common handlers
182
- *
183
- * The EXC handlers are given a name, and branch to name_common, or the
184
- * appropriate KVM or masking function. Vector handler verieties are as
185
- * follows:
186
- *
187
- * EXC_{REAL|VIRT}_BEGIN/END - used to open-code the exception
188
- *
189
- * EXC_{REAL|VIRT}  - standard exception
190
- *
191
- * EXC_{REAL|VIRT}_suffix
192
- *     where _suffix is:
193
- *   - _MASKABLE               - maskable exception
194
- *   - _OOL                    - out of line with trampoline to common handler
195
- *   - _HV                     - HV exception
196
- *
197
- * There can be combinations, e.g., EXC_VIRT_OOL_MASKABLE_HV
198
- *
199
- * The one unusual case is __EXC_REAL_OOL_HV_DIRECT, which is
200
- * an OOL vector that branches to a specified handler rather than the usual
201
- * trampoline that goes to common. It, and other underscore macros, should
202
- * be used with care.
203
- *
204
- * KVM handlers come in the following verieties:
205
- * TRAMP_KVM
206
- * TRAMP_KVM_SKIP
207
- * TRAMP_KVM_HV
208
- * TRAMP_KVM_HV_SKIP
209
- *
210
- * COMMON handlers come in the following verieties:
211
- * EXC_COMMON_BEGIN/END - used to open-code the handler
212
- * EXC_COMMON
213
- * EXC_COMMON_ASYNC
214
- *
215
- * TRAMP_REAL and TRAMP_VIRT can be used with BEGIN/END. KVM
216
- * and OOL handlers are implemented as types of TRAMP and TRAMP_VIRT handlers.
