blk_stat_add() calls {get,put}_cpu_ptr() in a loop, which entails
overhead of disabling/enabling preemption. The loop is under RCU
(i.e.short) anyway, so do get_cpu() in advance.

This is not the first attempt to fix building random configurations,
unfortunately the attempt in commit a07fc0bb483e ("RDMA/hns: Fix build
error") caused a new problem when CONFIG_INFINIBAND_HNS_HIP06=m
and CONFIG_INFINIBAND_HNS_HIP08=y:
drivers/infiniband/hw/hns/hns_roce_main.o:(.rodata+0xe60):
This patch adds system heap to the dma-buf heaps framework.
This allows applications to get a page-allocator backed dma-buf
for non-contiguous memory.
This code is an evolution of the Android ION implementation, so
thanks to its original authors and maintainters:

The patch titled

This change adds a KUnit test for the kernel doubly linked list
implementation in include/linux/list.h
Note that, at present, it only tests the list_ types (not the
singly-linked hlist_), and does not yet test all of the
list_for_each_entry* macros (and some related things like
list_prepare_entry)

This change fixes indirect call mismatches with function and function
graph tracing, which trip Control-Flow Integrity (CFI) checking.

Dear RT folks!
I'm pleased to announce the v5.2.19-rt11 patch set.

This change has been reverted and the original problem was sol
