-Subject: [PATCH] Port build to python3
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-* first tool of choice was 2to3
-* some parts were taken from [1] but during work it was found that this patch
-  introduces interesting effects - see hash functions. Working more on this
-  makes me guess that one has never worked...
-* Few parts were taken from upstream mirror [2]. Since they use six for porting
-  to python3 it adds us a new dependency.
-* To get a better overview what is going on or failing some additional messages
-  were added. The most verbose one is left disabled - see
-  python/mozbuild/mozbuild/configure/__init__.py / Line 310 onwards
-* major changes upstream on build are not to expect so upgrading should cause
-  little trouble and changes can be tracked by [3]
-* some solutions are workarounds/hacks so this patch will not be accepted
-  upstream. This should not be a problem for us: once mozjs >= 68 will arrive
-  we have to go to rust/cargo based build anyway.

+Subject: [PATCH] use <asm/sgidefs.h>
+
+Build fix for MIPS with musl libc
+
+The MIPS specific header <sgidefs.h> is provided by glibc and uclibc
+but not by musl. Regardless of the libc, the kernel headers provide
+<asm/sgidefs.h> which provides the same definitions, so use that
+instead.

-Bug 1495731 - remove JS_VOLATILE_ARM, it is no longer relevant.  r=waldo
-
-JS_VOLATILE_ARM was a workaround for a gcc 4.7 bug on B2G where it
-would generate unaligned word accesses that should have been
-individual byte accesses.  We now require at least gcc 6.1 (and ARM
-systems support unaligned accesses).

-Subject: [PATCH] fix compiling failure on mips64-n32 bsp
-
-- Tweak mips64-n32 with mips32
-
-- The toolchain of mips64-n32 supports both of macro
-  `__mips64' and `__mips__', but 32bit is required here.
-
-- N32 uses 64-bit registers but restricts addresses to 32 bits.
-  https://www.linux-mips.org/pub/linux/mips/doc/ABI/MIPS-N32-ABI-Handbook.pdf
-  Table 2-1 specifies the use of registers in n32 and native 64-bit mode.
-  From the table, N32 and N64 have the same registers
-
-Upstream-Status: Inappropriate [oe specific]
