* Following are the BOOK3S exception handler helper macros.
* Handlers come in a number of types, and each type has a number of varieties.
*
* EXC_REAL_* - real, unrelocated exception vectors
* EXC_VIRT_* - virt (AIL), unrelocated exception vectors
* TRAMP_REAL_* - real, unrelocated helpers (virt can call these)
* TRAMP_VIRT_* - virt, unreloc helpers (in practice, real can use)
* TRAMP_KVM - KVM handlers that get put into real, unrelocated
* EXC_COMMON - virt, relocated common handlers
*
* The EXC handlers are given a name, and branch to name_common, or the
* appropriate KVM or masking function. Vector handler verieties are as
* follows:
*
* EXC_{REAL|VIRT}_BEGIN/END - used to open-code the exception
*
* EXC_{REAL|VIRT} - standard exception
*
* EXC_{REAL|VIRT}_suffix
* where _suffix is:
* - _MASKABLE - maskable exception
* - _OOL - out of line with trampoline to common handler
* - _HV - HV exception
*
* There can be combinations, e.g., EXC_VIRT_OOL_MASKABLE_HV
*
* The one unusual case is __EXC_REAL_OOL_HV_DIRECT, which is
* an OOL vector that branches to a specified handler rather than the usual
* trampoline that goes to common. It, and other underscore macros, should
* be used with care.
*
* KVM handlers come in the following verieties:
* TRAMP_KVM
* TRAMP_KVM_SKIP
* TRAMP_KVM_HV
* TRAMP_KVM_HV_SKIP
*
* COMMON handlers come in the following verieties:
* EXC_COMMON_BEGIN/END - used to open-code the handler
* EXC_COMMON
* EXC_COMMON_ASYNC
*
* TRAMP_REAL and TRAMP_VIRT can be used with BEGIN/END. KVM
* and OOL handlers are implemented as types of TRAMP and TRAMP_VIRT handlers.
