Revert "lttng-modules: add bbappend"
lttng-modules v2.10.10 release with fixes is available now and recipe has been upgraded in OE-Core. So bbappend no longer required. This reverts commit 886d2063cd54069f831239febf2be118ab774d01.

-
-See upstream commit:
-
- commit 3d3539018d2cbd12e5af4a132636ee7fd8d43ef0

- mm: create the new vm_fault_t type
-
- Page fault handlers are supposed to return VM_FAULT codes, but some
- drivers/file systems mistakenly return error numbers. Now that all
- drivers/file systems have been converted to use the vm_fault_t return
- type, change the type definition to no longer be compatible with 'int'.
- By making it an unsigned int, the function prototype becomes
- incompatible with a function which returns int. Sparse will detect any
- attempts to return a value which is not a VM_FAULT code.
-
- VM_FAULT_SET_HINDEX and VM_FAULT_GET_HINDEX values are changed to avoid
- conflict with other VM_FAULT codes.

- None of synchronize_rcu_bh, synchronize_rcu_bh_expedited, call_rcu_bh,
- rcu_barrier_bh, synchronize_sched, synchronize_sched_expedited,
- call_rcu_sched, rcu_barrier_sched, get_state_synchronize_sched, and

- pipe: stop using ->can_merge
-
- Al Viro pointed out that since there is only one pipe buffer type to which
- new data can be appended, it isn't necessary to have a ->can_merge field in
- struct pipe_buf_operations, we can just check for a magic type.

- syscalls: Remove start and number from syscall_get_arguments() args
-
- At Linux Plumbers, Andy Lutomirski approached me and pointed out that the
- function call syscall_get_arguments() implemented in x86 was horribly
- written and not optimized for the standard case of passing in 0 and 6 for
- the starting index and the number of system calls to get. When looking at
- all the users of this function, I discovered that all instances pass in only
- 0 and 6 for these arguments. Instead of having this function handle
- different cases that are never used, simply rewrite it to return the first 6
- arguments of a system call.
-
- This should help out the performance of tracing system calls by ptrace,
- ftrace and perf.
