Bug Detailed Description:
Test assertion failure happens in kvm selftest rseq_test on the linux 6.1
release kernel. 

==== Test Assertion Failure ====
  rseq_test.c:268: i > (NR_TASK_MIGRATIONS / 2)
  pid=867071 tid=867071 errno=4 - Interrupted system call
     1  0x000000000040281d: main at rseq_test.c:268
     2  0x00007f8ef9444e4f: ?? ??:0
     3  0x00007f8ef9444efb: ?? ??:0
     4  0x00000000004028b4: _start at ??:?
  Only performed 2511 KVM_RUNs, task stalled too much?


Reproducing Steps:

git clone https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git
cd linux && git checkout v6.1 && make headers_install
cd tools/testing/selftests/kvm && make
./rseq_test

Actual Result:
==== Test Assertion Failure ====
  rseq_test.c:268: i > (NR_TASK_MIGRATIONS / 2)
  pid=867071 tid=867071 errno=4 - Interrupted system call
     1  0x000000000040281d: main at rseq_test.c:268

     3  0x00007f8ef9444efb: ?? ??:0
     4  0x00000000004028b4: _start at ??:?
  Only performed 2511 KVM_RUNs, task stalled too much?
