5.13: new patchset, a copy of 5.12, with some removed

The following patches have been removed, since they are ancient,
no other distro carries similar ones, and they seem to exist
solely to allow unportable behaviour.

* 00_all_0001-linux-stat.h-remove-__GLIBC__-checks.patch
* 00_all_0003-convert-PAGE_SIZE-usage.patch
* 00_all_0004-asm-generic-fcntl.h-namespace-kernel-file-structs.patch

+Subject: [PATCH] unifdef: drop unused errno.h include
+
+This is the only header on my system that ends up requiring kernel
+headers, so if the kernel headers aren't available, we end up being
+unable to install kernel headers :).
+
+Since this file doesn't actually use anything from errno.h, drop
+the include so it at least makes us a bit more robust on glibc.

+Subject: [PATCH] x86: do not build relocs tool when installing headers
+
+This isn't needed to install headers, so don't bother building it.
+Otherwise we run into a chicken/egg issue where we need the kernel
+headers in order to install the kernel headers.  It's also a waste
+of time.

+Subject: [PATCH] netlink: drop (int) cast on length arg in NLMSG_OK
+
+The NLMSG_OK macro compares three things:
+ - the len arg from the user
+ - a size_t: sizeof(struct nlmsghdr)
+ - an int: sizeof(struct nlmsghdr) casted
+ - an u32: the nlmsghdr->nlmsg_len member
+
+When building with -Wsign-compare, this macro triggers a signed compare
+warning.  This is because it compares len to an int, and then compares
+it to a u32.  If len is signed, we get a warning due to the last test.
+If len is unsigned, we get a warning due to the first test.  Like in
+strace:
+socketutils.c:145:8: warning: comparison between signed and unsigned
+                              integer expressions [-Wsign-compare]
+
+Lets drop the int cast on the first sizeof.  This way, once the user
+casts len to an unsigned value, everything shakes out correctly.

+Subject: [PATCH] uapi: fix System V buf header includes
+
+These headers rely on kernel types but don't include the other headers
+that define them.  So when you try to include them directly, you often
+hit build failures due to unknown types.
