      "message": "[XTENSA] Add support for configurable registers and coprocessors\n\nThe Xtensa architecture allows to define custom instructions and\nregisters. Registers that are bound to a coprocessor are only\naccessible if the corresponding enable bit is set, which allows\nto implement a \u0027lazy\u0027 context switch mechanism. Other registers\nneeds to be saved and restore at the time of the context switch\nor during interrupt handling.\n\nThis patch adds support for these additional states:\n\n- save and restore registers that are used by the compiler upon\n  interrupt entry and exit.\n- context switch additional registers unbound to any coprocessor\n- \u0027lazy\u0027 context switch of registers bound to a coprocessor\n- ptrace interface to provide access to additional registers\n- update configuration files in include/asm-xtensa/variant-fsf\n\nSigned-off-by: Chris Zankel \u003cchris@zankel.net\u003e\n"
