+Subject: [PATCH 3/3] remove inclusion of sysinfo.h in kernel.h
+
+the declaration of struct sysinfo clashes with userspace.
+it's not quite clear why that header was included from kernel.h,
+as none of its functionality is needed.

+Subject: [PATCH] include/uapi/linux/swab: Fix potentially missing
+ __always_inline
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Commit bc27fb68aaad ("include/uapi/linux/byteorder, swab: force inlining
+of some byteswap operations") added __always_inline to swab functions
+and commit 283d75737837 ("uapi/linux/stddef.h: Provide __always_inline to
+userspace headers") added a definition of __always_inline for use in
+exported headers when the kernel's compiler.h is not available.
+
+However, since swab.h does not include stddef.h, if the header soup does
+not indirectly include it, the definition of __always_inline is missing,
+resulting in a compilation failure, which was observed compiling the
+perf tool using exported headers containing this commit:
+
+In file included from /usr/include/linux/byteorder/little_endian.h:12:0,
+                 from /usr/include/asm/byteorder.h:14,
+                 from tools/include/uapi/linux/perf_event.h:20,
+                 from perf.h:8,
+                 from builtin-bench.c:18:
+/usr/include/linux/swab.h:160:8: error: unknown type name ‘__always_inline’
+ static __always_inline __u16 __swab16p(const __u16 *p)
+
+Fix this by replacing the inclusion of linux/compiler.h with
+linux/stddef.h to ensure that we pick up that definition if required,
+without relying on it's indirect inclusion. compiler.h is then included
+indirectly, via stddef.h.
+
