Merge tag 'core-entry-2025-07-29' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull generic entry code updates from Thomas Gleixner:
- Split the code into syscall and exception/interrupt parts to ease the
conversion of ARM[64] to the generic entry infrastructure
- Extend syscall user dispatching to support a single intercepted range
instead of the default single non-intercepted range. That allows
monitoring/analysis of a specific executable range, e.g. a library,
and also provides flexibility for sandboxing scenarios
- Cleanup and extend the user dispatch selftest
* tag 'core-entry-2025-07-29' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
entry: Split generic entry into generic exception and syscall entry
selftests: Add tests for PR_SYS_DISPATCH_INCLUSIVE_ON
syscall_user_dispatch: Add PR_SYS_DISPATCH_INCLUSIVE_ON
selftests: Fix errno checking in syscall_user_dispatch test
