stable inclusion from stable-v5.10.146 commit 9d18013dac863377c5a2acc27eebcbfb4450df5c category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I6D0VX
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=...
--------------------------------
[ Upstream commit 892deb48269c65376f3eeb5b4c032ff2c2979bd7 ]
We want to be able to call virt data exchange conditionally after gmc sw init to reserve bad pages as early as possible. Since this is a conditional call, we will need to call it again unconditionally later in the init sequence.
Refactor the data exchange function so it can be called multiple times without re-initializing the work item.
v2: Cleaned up the code. Kept the original call to init_exchange_data() inside early init to initialize the work item, afterwards call exchange_data() when needed.
