fs: create helper file_user_path() for user displayed mapped file path

2023-10-19T09:03:15Z

Overlayfs uses backing files with "fake" overlayfs f_path and "real" underlying f_inode, in order to use underlying inode aops for mapped files and to display the overlayfs path in /proc//maps. In preparation for storing the overlayfs "fake" path instead of the underlying "real" path in struct backing_file, define a noop helper file_user_path() that returns f_path for now. Use the new helper in procfs and kernel logs whenever a path of a mapped file is displayed to users.

ARCv2: entry: rearrange pt_regs slightly

2023-08-18T17:30:47Z

Instead of r26,fp,sp,r12,r30 order as fp,r30,r12,r26,sp - keeps SP at well known position (right abive hardware autosave) - r26,r12 saved specifically for ARCv2 (and not in ARCv3) kept closer for easy ifdef'ry later Signed-off-by: Vineet Gupta

ARC: entry: Add more common chores to EXCEPTION_PROLOGUE

2023-08-18T17:30:07Z

THe high level structure of most ARC exception handlers is 1. save regfile with EXCEPTION_PROLOGUE 2. setup r0: EFA (not part of pt_regs) 3. setup r1: pointer to pt_regs (SP) 4. drop down to pure kernel mode (from exception) 5. call the Linux "C" handler Remove the boiler plate code by moving #2, #3, #4 into #1. The exceptions to most exceptions are syscall Trap and Machine check which don't do some of above for various reasons, so call a newly introduced variant EXCEPTION_PROLOGUE_KEEP_AE (same as original EXCEPTION_PROLOGUE) Tested-by: Pavel Kozlov Signed-off-by: Vineet Gupta
