| Subject: powerpc/64s: Fix allnoconfig build since uaccess flush |
| |
| From: Stephen Rothwell <sfr@canb.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") |
