2023-10-30iommufd: Fix missing update of domains_itree after splitting iopt_areaKoichiro Den
In iopt_area_split(), if the original iopt_area has filled a domain and is linked to domains_itree, pages_nodes have to be properly reinserted. Otherwise the domains_itree becomes corrupted and we will UAF.

2023-10-30fbdev: stifb: Make the STI next font pointer a 32-bit signed offsetHelge Deller
The pointer to the next STI font is actually a signed 32-bit offset. With this change the 64-bit kernel will correctly subract the (signed 32-bit) offset instead of adding a (unsigned 32-bit) offset. It has no effect on 32-bit kernels. This fixes the stifb driver with a 64-bit kernel on qemu. Signed-off-by: Helge Deller <deller@gmx.de> Cc: stable@vger.kernel.org

2023-10-30parisc: Add nop instructions after TLB insertsJohn David Anglin
An excerpt from the PA8800 ERS states: * The PA8800 violates the seven instruction pipeline rule when performing TLB inserts or PxTLBE instructions with the PSW C bit on. The instruction will take effect by the 12th instruction after the insert or purge. I believe we have a problem with handling TLB misses. We don't fill the pipeline following TLB inserts. As a result, we likely fault again after returning from the interruption. The above statement indicates that we need at least seven instructions after the insert on pre PA8800 processors and we need 12 instructions on PA8800/PA8900 processors. Here we add macros and code to provide the required number instructions after a TLB insert.

2023-10-30parisc: simplify smp_prepare_boot_cpu()Russell King (Oracle)
smp_prepare_boot_cpu() reads the cpuid of the first CPU, printing a message to state which processor booted, and setting it online and present. This cpuid is retrieved from per_cpu(cpu_data, 0).cpuid, which is initialised in arch/parisc/kernel/processor.c:processor_probe() thusly: p = &per_cpu(cpu_data, cpuid); ... p->cpuid = cpuid; /* save CPU id */ Consequently, the cpuid retrieved seems to be guaranteed to also be zero, meaning that the message printed in this boils down to: pr_info("SMP: bootstrap CPU ID is 0\n"); Moreover, since kernel/cpu.c::boot_cpu_init() already sets CPU 0 to be present and online, there is no need to do this again in smp_prepare_boot_cpu(). Remove this code, and simplify the printk(). Signed-off-by: Russell King (Oracle) <rmk+kernel@armlinux.org.uk> Signed-off-by: Helge Deller <deller@gmx.de>
