- Removed an extraneous debug message from allocate_cachealigned_map - Changed extract_lsb_from_nodes to return 63 for the case where there was only one memory node. The prevents the creation of the dynamic hashmap. - Changed extract_lsb_from_nodes to use only the starting memory address of a node. On an ES7000, our nodes overlap the starting and ending address, meaning, that we see nodes like 00000 - 10000 10000 - 20000 But other systems have nodes whose start and end addresses do not overlap. For example: 00000 - 0FFFF 10000 - 1FFFF In this case, using the ending address will result in an LSB much lower than what is possible. In this case an LSB of 1 when in reality it should be 16.

Remove the statically allocated memory to NUMA node hash map in favor of a dynamically allocated memory to node hash map (it is cache aligned). This patch has the nice side effect in that it allows the hash map to grow for systems with large amounts of memory (256GB - 1TB), but suffer from having small PCI space tacked onto the boot node (which is somewhere between 192MB to 512MB on the ES7000).

This does user copies in fs write() into the page cache with write combining. This pushes the destination out of the CPU's cache, but allows higher bandwidth in some case. The theory is that the page cache data is usually not touched by the CPU again and it's better to not pollute the cache with it. Also it is a little faster. Signed-off-by: -

This reverts some bogosity from the dynamic command-line changes made on sparc32 and sparc64. Drivers such as drivers/sbus/char/openprom.c reference saved_command_line, and can be modular. The boot_command_line is __initdata, yet the dynamic command-line changes add modular exports of that symbol, obviously wrong. Signed-off-by:David S. Miller <davem@davemloft.net>

Since we look in both source and object directories for localversion* files, we accidentally ended up getting them twice. Use 'sort -u' to avoid that. Reported-by:

Regarding RFC3775, MH payload proto field should be IPPROTO_NONE. Otherwise it must be discarded (and the receiver should send ICMP error). We assume filter should drop such piggyback everytime to disallow slipping through firewall rules, even the final receiver will discard it. Signed-off-by:

NF_CT_STAT_INC assumes rcu_read_lock in nf_hook_slow disables preemption as well, making it legal to use __get_cpu_var without disabling preemption manually. The assumption is not correct anymore with preemptable RCU, additionally we need to protect against softirqs when not holding nf_conntrack_lock. Add NF_CT_STAT_INC_ATOMIC macro, which disables local softirqs, and use where necessary. Signed-off-by:

Many struct inode_operations in the kernel can be "const". Marking them const moves these to the .rodata section, which avoids false sharing with potential dirty data. In addition it'll catch accidental writes at compile time to these shared resources. Signed-off-by:
