Subject: [PATCH 5.9 102/152] powerpc/64s: Fix allnoconfig build since uaccess flush
From: Stephen Rothwell <sfr@...b.auug.org.au>
[ Upstream commit b6b79dd53082db11070b4368d85dd6699ff0b063 ]
Using DECLARE_STATIC_KEY_FALSE needs linux/jump_table.h.
Otherwise the build fails with eg:
arch/powerpc/include/asm/book3s/64/kup-radix.h:66:1: warning: data definition has no type or storage class
66 | DECLARE_STATIC_KEY_FALSE(uaccess_flush_key);
Fixes: 9a32a7e78bd0 ("powerpc/64s: flush L1D after user accesses")
