    Subject[PATCH 5.18 0945/1095] powerpc/64e: Fix kexec build error
    Date
    From: Michael Ellerman <mpe@ellerman.id.au>

    [ Upstream commit 4cfa6ff24a9744ba484521c38bea613134fbfcb3 ]

    When building ppc64_book3e_allmodconfig the build fails with:

    arch/powerpc/kexec/file_load_64.c:1063:14: error: implicit declaration of function ‘firmware_has_feature’
    1063 | if (!firmware_has_feature(FW_FEATURE_LPAR))
    | ^~~~~~~~~~~~~~~~~~~~

    Add a direct include of asm/firmware.h to fix the error.

    Fixes: b1fc44eaa9ba ("pseries/iommu/ddw: Fix kdump to work in absence of ibm,dma-window")
