Linux/Unix 主机中安装的一个或多个程序包受到一个漏洞影响，而供应商没有提供补丁程序。

  - 已修复 Linux 内核中的下列漏洞：powerpc/rtas: use correct function name for resetting TCE tables The PAPR spec spells the function name as ibm,reset-pe-dma-windows but in practice firmware uses the singular form: ibm,reset-pe-dma-window in the device tree. Since we have the wrong spelling in the RTAS function table, reverse lookups (token -> name) fail and warn: unexpected failed lookup for token 86 WARNING: CPU: 1 PID: 545 at arch/powerpc/kernel/rtas.c:659

Use the correct spelling to match firmware's behavior, adjusting the related constants to match. (CVE-2024-26847)
