- * We get here for syscalls that don't have a lightweight
- * handler. For those, we need to bubble down into the kernel
- * and that requires setting up a minimal pt_regs structure,
- * and initializing the CPU state more or less as if an
- * interruption had occurred. To make syscall-restarts work,
- * we setup pt_regs such that cr_iip points to the second
- * instruction in syscall_via_break. Decrementing the IP
- * hence will restart the syscall via break and not
- * decrementing IP will return us to the caller, as usual.
- * Note that we preserve the value of psr.pp rather than
- * initializing it from dcr.pp. This makes it possible to
- * distinguish fsyscall execution from other privileged
- * execution.
- *
- * On entry:
- * - normal fsyscall handler register usage, except
- * that we also have:
- * - r18: address of syscall entry point
- * - r21: ar.fpsr
- * - r26: ar.pfs
- * - r27: ar.rsc
- * - r29: psr
- *
- * We used to clear some PSR bits here but that requires slow
- * serialization. Fortuntely, that isn't really necessary.
- * The rationale is as follows: we used to clear bits
- * ~PSR_PRESERVED_BITS in PSR.L. Since
- * PSR_PRESERVED_BITS==PSR.{UP,MFL,MFH,PK,DT,PP,SP,RT,IC}, we
- * ended up clearing PSR.{BE,AC,I,DFL,DFH,DI,DB,SI,TB}.
- * However,
- *
- * PSR.BE : already is turned off in __kernel_syscall_via_epc()
- * PSR.AC : don't care (kernel normally turns PSR.AC on)
- * PSR.I : already turned off by the time fsys_bubble_down gets
- * invoked
- * PSR.DFL: always 0 (kernel never turns it on)
- * PSR.DFH: don't care --- kernel never touches f32-f127 on its own
- * initiative
- * PSR.DI : always 0 (kernel never turns it on)
- * PSR.SI : always 0 (kernel never turns it on)
- * PSR.DB : don't care --- kernel never enables kernel-level
- * breakpoints
- * PSR.TB : must be 0 already; if it wasn't zero on entry to
- * __kernel_syscall_via_epc, the branch to fsys_bubble_down
- * will trigger a taken branch; the taken-trap-handler then
- * converts the syscall into a break-based system-call.
