Hi, the following patch: - correct the err variable tested twice when _NSIG_WORDS == 1 (unlikely to happen, but ..) - remove some |= in favor of = because we don't need to 'pack' err Signed-off-by:

In unprivileged Xen domains, all that __ioremap() does is a "return NULL", which causes dmi_iterate() to crash the kernel at boot time. This trivial check bails dmi_iterate() out of the loop when it finds that the ioremap() returned a NULL pointer. (akpm: this fix goes beyond xen - ioremap can return NULL) Signed-off-by:

The g5 code has special hooks to "hide" some PCI devices when they are off. Currently, this code involves some calls to match a pci_dev from the open firmware node and such things that are causing some problems with the latest version of my sungem driver who wants to do some of this in atomic contexts. This patch moves that to a list of struct device_node instead, which also ends up simplifying the code. Later, I'll go back to manipulating PCI devices in a clean way when Brian King's PCI blocking patch gets in, but only after I change sungem again to never call these in atomic context. This is a 3 step transition basically Signed-off-by:

Replace CONFIG_IRQ_ALL_CPUS with a boot option (noirqdistrib). Compile options arent much use on a distro kernel. This also removes the ppc64 use of smp_threads_ready. I considered removing the option completely but we have had problems in the past with firmware bugs. In those cases the boot option would have helped. Signed-off-by:

When the update_process_times call was moved out of do_timer for the UP case, the replicator didn't track down the hiding and just added ifndef SMP. This removes the ifdefs and the indirection of calling another file for one function in a third file. I also removed the per-cpu multipler and counter. On some architectures (x86 and sparc64) these are set via /proc/profile setup_profiling_timer to increase the timer interrupt by a factor over HZ. However, this was not not implemented for ppc (like several other architectures), so it was just decrementing, testing, and setting per-cpu variables back to 1. Signed-off-by:

There is a problem in the TLB Miss (and Error, as they jump to the Miss handler) handlers. The problem is that when an app spans more than one L1 entry, we don't have all of the correct information, and do_page_fault() things a protection fault happened, when it didn't really. The fix for this is to modify the handlers slightly to force a TLB Error in this case. Lots of suggestions from: Joakim Tjernlund <joakim.tjernlund@lumentis.se> Signed-off-by:

On most embedded PPC systems we either have a core CPU and chipset (MPC10x, TSI10x, Marvell, etc.) or a system-on-chip device (4xx, 8xx, 82xx, 85xx, etc.). Some of these sub-archs have been using the On Chip Peripheral (OCP) driver model. The functionality that OCP provide has been replaced by the generic driver model and platform_device. Also, some of these device may exist across a number of architectures (PPC, MIPS, ARM) such that some information that is shared between the architecture and driver needs to exist outside of either. The ppc_sys changes add a standard way for PowerPC systems to describe the devices and systems that exist in the sub-arch. Additionally, we are able to discover which system we are and manage which devices are actually registered and any platform specific fixups that may be needed. Signed-off-by:

The audit control messages are sent over netlink. Permission checks are done on the process receiving the message, which may not be the same as the process sending the message. This patch switches the netlink_send security hooks to calculate the effective capabilities based on the sender. Then audit_receive_msg performs capability checks based on that. It also introduces the CAP_AUDIT_WRITE and CAP_AUDIT_CONTROL capabilities, and replaces the previous CAP_SYS_ADMIN checks in audit code with the appropriate checks. - Simplified dummy_netlink_send given that dummy now keeps track of capabilities. - Many fixes based on feedback from <linux-audit@redhat.com> list. - Removed the netlink_msg_type helper function. - Switch to using CAP_AUDIT_WRITE and CAP_AUDIT_CONTROL.

This patch lets us use TIOCMIWAIT and TIOCGICOUNT from a 32-bit process on a 64-bit processor. TIOCMIWAIT uses the argument as a bitmap of things to wait for. The argument for TIOCGICOUNT points to a struct serial_icounter_struct, which only contains ints and arrays of int. Signed-off-by:

The recent oprofile changes for Motorola e500 broke oprofile for other CPUs. This patch fixes the build. Proper support for the G3/G4 PMCs would be interesting, and making sure the basic interrupt PC sampling still works on CPUs that don't have supported PMCs too... Signed-off-by:

This is a patch to generic_file_buffered_write() to correctly handle partial O_DIRECT writes (because of unallocated blocks) when there is more than 1 iovec. Without this patch, the code is writing the wrong iovec (it writes the first iovec a 2nd time). Included is a test program dio_bug.c that shows the problem by: writing 4k to offset 4k writing 4k to offset 12k writing 8k to offset 4k The result is that 8k write writes the 1st 4k of the buffer twice. $ rm f; ./dio_bug f wrong value offset 8k expected 0x33 got 0x11 wrong value offset 10k expected 0x44 got 0x22 with patch $ rm f; ./dio_bug f #define _GNU_SOURCE #include <sys/types.h> #include <unistd.h> #include <stdlib.h> #include <fcntl.h> #include <sys/uio.h> main(int argc, char **argv) { int fd; char *buf; int i; struct iovec v[2]; fd = open(argv[1], O_DIRECT|O_RDWR|O_CREAT, 0666); if (fd < 0) { perror("open"); exit(1); } buf = valloc(8192); lseek(fd, 0x1000, SEEK_SET); memset(buf, 0x11, 2048); memset(buf+2048, 0x22, 2048); i = write(fd, buf, 4096); /* 4k write of 0x11 and 0x22 at 4k */ lseek(fd, 0x3000, SEEK_SET); memset(buf, 0x55, 2048); memset(buf+2048, 0x66, 2048); i = write(fd, buf, 4096); /* 4k write of 0x55 and 0x66 at 12k */ lseek(fd, 0x1000, SEEK_SET); i = read(fd, buf, 4096); memset(buf+4096, 0x33 , 2048); memset(buf+4096+2048, 0x44 , 2048); v[0].iov_base = buf; v[0].iov_len = 4096; v[1].iov_base = buf + 4096; v[1].iov_len = 4096; lseek(fd, 0x1000, SEEK_SET); i = writev(fd, v, 2); /* 8k write of 0x11, 0x22, 0x33, 0x44 at 4k */ lseek(fd, 0x2000, SEEK_SET); i = read(fd, buf, 4096); if (buf[0] != 0x33) printf("wrong value offset 8k expected 0x33 got 0x%x\n", buf[0]); if (buf[2048] != 0x44) printf("wrong value offset 10k expected 0x44 got 0x%x\n", buf[2048]); } Signed-off-by: -
