On the syscall tracing path, we call out to secure_computing() to allow seccomp to check the syscall number being attempted. As part of this, a SIGTRAP may be sent to the tracer and the syscall could be re-written by a subsequent SET_SYSCALL ptrace request. Unfortunately, this new syscall is ignored by the current code unless TIF_SYSCALL_TRACE is also set on the current thread. This patch slightly reworks the enter path of the syscall tracing code so that we always reload the syscall number from current_thread_info()->syscall after the potential ptrace traps.

When a PL310 cache is used on a system that provides hardware coherency, the outer cache sync operation is useless, and can be skipped. Moreover, on some systems, it is harmful as it causes deadlocks between the Marvell coherency mechanism, the Marvell PCIe controller and the Cortex-A9. To avoid this, this commit introduces a new Device Tree property 'arm,io-coherent' for the L2 cache controller node, valid only for the PL310 cache. It identifies the usage of the PL310 cache in an I/O coherent configuration. Internally, it makes the driver disable the outer cache sync operation. Note that technically speaking, a fully coherent system wouldn't require any of the other .outer_cache operations. However, in practice, when booting secondary CPUs, these are not yet coherent, and therefore a set of cache maintenance operations are necessary at this point. This explains why we keep the other .outer_cache operations and only ->sync is disabled. While in theory any write to a PL310 register could cause the deadlock, in practice, disabling ->sync is sufficient to workaround the deadlock, since the other cache maintenance operations are only used in very specific situations. Contrary to previous versions of this patch, this new version does not simply NULL-ify the ->sync member, because the l2c_init_data structures are now 'const' and therefore cannot be modified, which is a good thing. Therefore, this patch introduces a separate l2c_init_data instance, called of_l2c310_coherent_data.

Previously, the lower limit for the MIPS SC initialization loop was set incorrectly allowing one extra loop leading to writes beyond the MSC ioremap'd space. More precisely, the value of the 'imp' in the last loop increased beyond the msc_irqmap_t boundaries and as a result of which, the 'n' variable was loaded with an incorrect value. This value was used later on to calculate the offset in the MSC01_IC_SUP which led to random crashes like the following one: CPU 0 Unable to handle kernel paging request at virtual address e75c0200, epc == 8058dba4, ra == 8058db90 [...] Call Trace: [<8058dba4>] init_msc_irqs+0x104/0x154 [<8058b5bc>] arch_init_irq+0xd8/0x154 [<805897b0>] start_kernel+0x220/0x36c Kernel panic - not syncing: Attempted to kill the idle task!

The skb->pkt_type field is defined as follows: u8 pkt_type:3, fclone:2, ipvs_property:1, peeked:1, nf_trace:1 resulting to the following layout in big-endian systems [pkt_type][fclone][ipvs_propery][peeked][nf_trace] ^ ^ | | LSB MSB As a result, the existing code did not work because it was trying to match pkt_type == 7 whereas in reality it is 7<<5 on big-endian systems. This has been fixed in the interpreter in 0dcceabb "net: filter: fix SKF_AD_PKTTYPE extension on big-endian" The fix is to look for 7<<5 on big-endian systems for the pkt_type field, and shift by 5 so the packet type will be at the lower 3 bits of the A register.
