+Subject: [PATCH] Bug 2040125 - add GetSystemProxyDirect() to libproxy path
+ r=valentin,necko-reviewers
+
+In bmo #2028356 a "fast-path to skip proxy resolution[...]" was added,
+but the required method GetSystemProxyDirect() was not added for
+libproxy-enabled builds (all other cases - general Unix without
+libproxy, OSX, Windows - got that function).
+
+This makes a "--enable-libproxy" build (MOZ_ENABLE_LIBPROXY) fail at
+startup, as the symbol for nsUnixSystemProxySettings::GetSystemProxyDirect()
+does not resolve.
+
+This adds GetSystemProxyDirect() to the MOZ_ENABLE_LIBPROXY case - it's
+trivial, as we cannot know what libproxy will return for a specific URL,
+thus the fast-path does not apply and we can just return "false".

+Subject: [PATCH] riscv64: Use long tail jump for xptcall stubs
+
+The riscv64 xptcall stubs currently jump to SharedStub with a plain
+`j SharedStub`. This emits an R_RISCV_JAL relocation, whose range is
+limited to +/- 1 MiB.
+
+When linking large optimized libxul builds, especially with LTO enabled,
+the generated StubN functions may be placed too far away from SharedStub.
+This causes lld to fail with relocation errors such as:
+
+  relocation R_RISCV_JAL out of range: ... references SharedStub
+
+Use `tail SharedStub` instead. This preserves the tail-call semantics of
+the original jump while allowing the assembler/linker to generate a
+relaxable long branch sequence when needed.

+Subject: [PATCH] riscv64: libyuv: add row_rvv.cc / scale_rvv.cc to gypi
+
+Without these, linking libxul on riscv64 with -march including the V
+extension fails with undefined references to *Row_RVV symbols, e.g.
+
+  ld.lld: error: undefined hidden symbol: J400ToARGBRow_RVV
+  >>> referenced by yuv_convert.cpp:333
+
+Both files are self-guarded with __riscv_vector, so listing them
+unconditionally alongside the LoongArch lsx/lasx entries is safe for
+other architectures.
