This patch against ia64-test-2.6.12 is needed for forthcoming Altix chipsets. It renames geoid_any_t to geoid_common_t and splits the 8bit 'slab' field into two 4bit fields for 'slab' and 'slot'. Similar changes in the Altix SAL will retain backward compatibility for old kernels. Signed-off-by: NMark Goodwin <markgw@sgi.com> Signed-off-by: NTony Luck <tony.luck@intel.com>

This patch introduces using the quicklists for pgd, pmd, and pte levels by combining the alloc and free functions into a common set of routines. This greatly simplifies the reading of this header file. This patch is simple but necessary for large numa configurations. It simply ensures that only pages from the local node are added to a cpus quicklist. This prevents the trapping of pages on a remote nodes quicklist by starting a process, touching a large number of pages to fill pmd and pte entries, migrating to another node, and then unmapping or exiting. With those conditions, the pages get trapped and if the machine has more than 100 nodes of the same size, the calculation of the pgtable high water mark will be larger than any single node so page table cache flushing will never occur. I ran lmbench lat_proc fork and lat_proc exec on a zx1 with and without this patch and did not notice any change. On an sn2 machine, there was a slight improvement which is possibly due to pages from other nodes trapped on the test node before starting the run. I did not investigate further. This patch shrinks the quicklist based upon free memory on the node instead of the high/low water marks. I have written it to enable preemption periodically and recalculate the amount to shrink every time we have freed enough pages that the quicklist size should have grown. I rescan the nodes zones each pass because other processess may be draining node memory at the same time as we are adding.

- make pfm_sysctl a global such that it is possible to enable/disable debug printk in sampling formats using PFM_DEBUG. - remove unused pfm_debug_var variable - fix a bug in pfm_handle_work where an BUG_ON() could be triggered. There is a path where pfm_handle_work() can be called with interrupts enabled, i.e., when TIF_NEED_RESCHED is set. The fix correct the masking and unmasking of interrupts in pfm_handle_work() such that we restore the interrupt mask as it was upon entry. signed-off-by: Nstephane eranian <eranian@hpl.hp.com> Signed-off-by: NTony Luck <tony.luck@intel.com>

Change the value of the SAL call number for a new SAL request. The initial implementation in the PROM did not match what the OS expected. Since the OS can run on PROMs that do not implement the new call, changing the call number avoids the issue. New PROMs will implement the new call number. (This avoids problems with the 4.05 PROM).

The SELinux hooks invoke ipv6_skip_exthdr() with an incorrect length final argument. However, the length argument turns out to be superfluous. I was just reading ipv6_skip_exthdr and it occured to me that we can get rid of len altogether. The only place where len is used is to check whether the skb has two bytes for ipv6_opt_hdr. This check is done by skb_header_pointer/skb_copy_bits anyway. Now it might appear that we've made the code slower by deferring the check to skb_copy_bits. However, this check should not trigger in the common case so this is OK. Signed-off-by: NHerbert Xu <herbert@gondor.apana.org.au> Signed-off-by: NDavid S. Miller <davem@davemloft.net>

The problem is that when doing MTU discovery, the too-large segments in the write queue will be calculated as having a pcount of >1. When tcp_write_xmit() is trying to send, tcp_snd_test() fails the cwnd test when pcount > cwnd. The segments are eventually transmitted one at a time by keepalive, but this can take a long time. This patch checks if TSO is enabled when setting pcount. Signed-off-by: NJohn Heffner <jheffner@psc.edu> Signed-off-by: NDavid S. Miller <davem@davemloft.net>

The NAT changes in 2.6.11 changed the position where helpers are called and perform packet mangling. Before 2.6.11, a NAT helper was called before the packet was NATed and had its sequence number adjusted. Since 2.6.11, the helpers get packets with already adjusted sequence numbers. This breaks sequence number adjustment, adjust_tcp_sequence() needs the original sequence number to determine whether a packet was a retransmission and to store it for further corrections. It can't be reconstructed without more information than available, so this patch restores the old order by calling helpers from a new conntrack hook two priorities below ip_conntrack_confirm() and adjusting the sequence number from a new NAT hook one priority below ip_conntrack_confirm().

Turns __get_unaligned() and __put_unaligned into macros.

This patch is required to support cpu removal for IPF systems. Existing code just fakes the real offline by keeping it run the idle thread, and polling for the bit to re-appear in the cpu_state to get out of the idle loop. For the cpu-offline to work correctly, we need to pass control of this CPU back to SAL so it can continue in the boot-rendez mode. This gives the SAL control to not pick this cpu as the monarch processor for global MCA events, and addition does not wait for this cpu to checkin with SAL for global MCA events as well. The handoff is implemented as documented in SAL specification section 3.2.5.1 "OS_BOOT_RENDEZ to SAL return State" Signed-off-by: NAshok Raj <ashok.raj@intel.com> Signed-off-by: NTony Luck <tony.luck@intel.com>

Provide support for drivers/char/rtc.c ioctls in the Mostek rtc driver as well as the Sparc specific RTCGET and RTCSET. This allows userspace to be much less messy. Currently util-linux and other spots jump through hoops trying various ioctl variants until it hits the right one whatever driver actually being used supports. Eventually all of this should move over to the genrtc.c driver, but not today... While we are here, fix up the register types for sparse. Thanks to Frans Pop for helping point out this issue.

由 David Mosberger-Tang 提交于
The ia64-version of fls() never worked as intended (the bitnumbering was off by 1 and fls(0) was undefined). This patch fixes the problem by using a popcnt-based fls(), which on McKinley-derived cores is slightly faster than both ia64_fls() and generic_fls(). The resulting code, however, is bigger (7-8 bundles instead of about 3 bundles). Also switch ia64_popcnt() to __builtin_popcountl() for GCC v3.4 or newer since the compiler can predicate that and schedule it better.

ARM26 define FIRST_USER_ADDRESS as PAGE_SIZE (beyond the machine vectors when they are mapped low), and use that definition in place of locally defined MIN_MAP_ADDR.
