This series contains a few cleanups and fixes to update-linux-headers.sh,
which I needed or found in order to pass CI for the SEV-SNP patches.
First, updating linux-headers/ fails due to the lack of
arch/loongarch/include/uapi/asm/bitsperlong.h. I am not sure if I am
doing something wrong but it is caused by commit 3efc75ad9d9
("scripts/update-linux-headers.sh: Remove temporary directory inbetween",
2024-05-29); if so, I guess I'm 1-1 with Thomas given my own bug in
commit 66210a1a30 that he fixed.
Before commit 3efc75ad9d9, the missing file would incorrectly cause stale
files to be included in linux-headers/. The files were never committed
to qemu.git, but were wrong nevertheless. The build would just use
the system version of the files, which is opposite to the idea of
importing Linux header files into QEMU's tree.
Second, pvpanic.h was incorrectly included in a slightly different
path than what is used in Linux.
Third, SNP host-side patches will need linux/kvm_para.h, because some
of the supported distros do not have a definition for KVM_HC_MAP_GPA_RANGE.
Including it is a bit complicated because we also have a version of
x86's kvm_para.h under include/standard-headers/; linux/kvm_para.h
tries to include <asm/kvm_para.h> and that could cause conflicts.
So, the linux/kvm_para.h is also placed in include/standard-headers
(patch 4).
