openrisc: Add floating point regset (2023-04-26 15:08:06 +0100)
----------------------------------------------------------------
OpenRISC update for 6.4
Two things for OpenRISC this cycle.
- Small cleanup for device tree cpu iteration from Rob Herring
- Add support for storing, restoring and accessing user space FPU state, to
allow for libc to support the FPU on OpenRISC.
----------------------------------------------------------------
Rob Herring (1):
openrisc: Use common of_get_cpu_node() instead of open-coding
Stafford Horne (4):
openrisc: Properly store r31 to pt_regs on unhandled exceptions
openrisc: Support storing and restoring fpu state
openrisc: Support floating point user api
openrisc: Add floating point regset
