-Subject: [PATCH] linux-user: fix to handle variably sized SIOCGSTAMP with new
- kernels
-MIME-Version: 1.0
-Content-Type: text/plain; charset=utf8
-Content-Transfer-Encoding: 8bit
-
-The SIOCGSTAMP symbol was previously defined in the
-asm-generic/sockios.h header file. QEMU sees that header
-indirectly via sys/socket.h
-
-In linux kernel commit 0768e17073dc527ccd18ed5f96ce85f9985e9115
-the asm-generic/sockios.h header no longer defines SIOCGSTAMP.
-Instead it provides only SIOCGSTAMP_OLD, which only uses a
-32-bit time_t on 32-bit architectures.
-
-The linux/sockios.h header then defines SIOCGSTAMP using
-either SIOCGSTAMP_OLD or SIOCGSTAMP_NEW as appropriate. If
-SIOCGSTAMP_NEW is used, then the tv_sec field is 64-bit even
-on 32-bit architectures
-
-To cope with this we must now convert the old and new type from
-the target to the host one.

-    q35: Revert to kernel irqchip
-
-    Commit b2fc91db8447 ("q35: set split kernel irqchip as default") changed
-    the default for the pc-q35-4.0 machine type to use split irqchip, which
-    turned out to have disasterous effects on vfio-pci INTx support.  KVM
-    resampling irqfds are registered for handling these interrupts, but
-    these are non-functional in split irqchip mode.  We can't simply test
-    for split irqchip in QEMU as userspace handling of this interrupt is a
-    significant performance regression versus KVM handling (GeForce GPUs
-    assigned to Windows VMs are non-functional without forcing MSI mode or
-    re-enabling kernel irqchip).
-
-    The resolution is to revert the change in default irqchip mode in the
-    pc-q35-4.1 machine and create a pc-q35-4.0.1 machine for the 4.0-stable
-    branch.  The qemu-q35-4.0 machine type should not be used in vfio-pci
-    configurations for devices requiring legacy INTx support without
-    explicitly modifying the VM configuration to use kernel irqchip.

+Subject: [PATCH] build: -no-pie is no functional linker flag
+
+Recent binutils changes dropping unsupported options [1] caused a build
+issue in regard to the optionroms.
+
+  ld -m elf_i386 -T /<<PKGBUILDDIR>>/pc-bios/optionrom//flat.lds -no-pie \
+    -s -o multiboot.img multiboot.o
+  ld.bfd: Error: unable to disambiguate: -no-pie (did you mean --no-pie ?)
+
+This isn't really a regression in ld.bfd, filing the bug upstream
+revealed that this never worked as a ld flag [2] - in fact it seems we
+were by accident setting --nmagic).
+
+Since it never had the wanted effect this usage of LDFLAGS_NOPIE, should be
+droppable without any effect. This also is the only use-case of LDFLAGS_NOPIE
+in .mak, therefore we can also remove it from being added there.
