| | * [PATCH] x86_64: GART DMA merging fixAndi Kleen2006-02-131-4/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Don't touch the non DMA members in the sg list in dma_map_sg in the IOMMU Some drivers (in particular ST) ran into problems because they reused the sg lists after passing them to pci_map_sg(). The merging procedure in the K8 GART IOMMU corrupted the state. This patch changes it to only touch the dma* entries during merging, but not the other fields. Approach suggested by Dave Miller.

| | * [PATCH] arch/x86_64/kernel/traps.c PTRACE_SINGLESTEP oopsJohn Blackwood2006-02-131-1/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We found a problem with x86_64 kernels with preemption enabled, where having multiple tasks doing ptrace singlesteps around the same time will cause the system to 'oops'. The problem seems that a task can get preempted out of the do_debug() processing while it is running on the DEBUG_STACK stack. If another task on that same cpu then enters do_debug() and uses the same per-cpu DEBUG_STACK stack, the previous preempted tasks's stack contents can be corrupted, and the system will oops when the preempted task is context switched back in again. The typical oops looks like the following: Unable to handle kernel paging request at ffffffffffffffae RIP: <ffffffff805452a1>{thread_return+34} PGD 103027 PUD 102429067 PMD 0 Oops: 0002 [1] PREEMPT SMP CPU 0 Modules linked in: Pid: 3786, comm: ssdd Not tainted 2.6.15.2 #1 RIP: 0010:[<ffffffff805452a1>] <ffffffff805452a1>{thread_return+34} RSP: 0018:ffffffff80824058 EFLAGS: 000136c2 RAX: ffff81017e12cea0 RBX: 0000000000000000 RCX: 00000000c0000100 RDX: 0000000000000000 RSI: ffff8100f7856e20 RDI: ffff81017e12cea0 RBP: 0000000000000046 R08: ffff8100f68a6000 R09: 0000000000000000 R10: 0000000000000000 R11: ffff81017e12cea0 R12: ffff81000c2d53e8 R13: ffff81017f5b3be8 R14: ffff81000c0036e0 R15: 000001056cbfc899 FS: 00002aaaaaad9b00(0000) GS:ffffffff80883800(0000) knlGS:0000000000000000 CS: 0010 DS: 0000 ES: 0000 CR0: 000000008005003b CR2: ffffffffffffffae CR3: 00000000f6fcf000 CR4: 00000000000006e0 Process ssdd (pid: 3786, threadinfo ffff8100f68a6000, task ffff8100f7856e20) Stack: ffffffff808240d8 ffffffff8012a84a ffff8100055f6c00 0000000000000020 0000000000000001 ffff81000c0036e0 ffffffff808240b8 0000000000000000 0000000000000000 0000000000000000 Call Trace: <#DB> <ffffffff8012a84a>{try_to_wake_up+985} <ffffffff8012c0d3>{kick_process+87} <ffffffff8013b262>{signal_wake_up+48} <ffffffff8013b5ce>{specific_send_sig_info+179} <ffffffff80546abc>{_spin_unlock_irqrestore+27} <ffffffff8013b67c>{force_sig_info+159} <ffffffff801103a0>{do_debug+289} <ffffffff80110278>{sync_regs+103} <ffffffff8010ed9a>{paranoid_userspace+35} Unable to handle kernel paging request at 00007fffffb7d000 RIP: <ffffffff8010f2e4>{show_trace+465} PGD f6f25067 PUD f6fcc067 PMD f6957067 PTE 0 Oops: 0000 [2] PREEMPT SMP This patch disables preemptions for the task upon entry to do_debug(), before interrupts are reenabled, and then disables preemption before exiting do_debug(), after disabling interrupts.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When the sclp interface takes very long to serve a request, the sclp core driver will report a failed request to the sclp tty driver even though the request is still being processed by the sclp interface. Eventually the sclp interface completes the request and updates some fields in the request buffer which leads to a corrupted tty pages list. The next time function sclp_tty_write_room is called, the corrupted list will be traversed, resulting in an oops. To avoid this remove the busy retry limit and increase retry intervals.

We were writing back a timeout larger than the original. We _deliberately_ round up, since we know we must wait at _least_ as long as the caller asks us to. The patch adds a couple of helper functions for magnitude comparison of timespecs and of timevals, and uses them to prevent the various poll and select functions from returning a timeout which is larger than the one which was passed in. The patch also fixes a bug in compat_sys_pselect7(): it was adding the new timeout value to the old one and was returning that. It should just return the new timeout value. (We have various handy timespec/timeval-to-from-nsec conversion functions in time.h. But this code open-codes it all). Cc: "David S.

Since the current Linux code relies on it use a mixed mode with both PIT for the interrupt and HPET counters for the time keeping. That was already implemented, but didn't work properly because it was still using the last interrupt offset in HPET. This resulted in x460 not booting. Fix this up by using the free running HPET counter. Shouldn't affect any other machine because they either use full HPET mode or no HPET at all. TBD needs a similar 32bit fix.

The result is that on 32-bit platforms we don't have all the information needed to implement fstatat64. This patch modifies the code to pass up 64-bit information if __ARCH_WANT_STAT64 is defined. I renamed the syscall entry point to make this clear. Other archs will continue to use the existing code. On x86-64 the compat code is implemented using a new sys32_ function. this is what is done for the other stat syscalls as well. This patch might break some other archs (those which define __ARCH_WANT_STAT64 and which already wired up the syscall). Yet others might need changes to accomodate the compatibility mode. I really don't want to do that work because all this stat handling is a mess (more so in glibc, but the kernel is also affected). It should be done by the arch maintainers. I'll provide some stand-alone test shortly. Those who are eager could compile glibc and run 'make check' (no installation needed). The patch below has been tested on x86 and x86-64.

| * | [PATCH] libata: add per-device max_sectorsTejun Heo2006-02-124-17/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If a low level driver wants to control max_sectors, it had to adjust ap->host->max_sectors and set ATA_DFLAG_LOCK_SECTORS to tell ata_scsi_slave_config not to override the limit. This is not only cumbersome but also incorrect for hosts which support more than one devices per port. This patch adds per-device ->max_sectors. If the field is unset (zero), libata core layer will adjust ->max_sectors according to default rules. If the field is set, libata honors the setting.

| | | | | | | | | | | | | | | | | | | | | | | | | | | cdb_len is per-device property. Sharing cdb_len on ap results in inaccurate configuration on revalidation and hotplugging. This patch makes cdb_len per-device. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jgarzik@pobox.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ata_dev_knobble() unconditionally used the first device of the port to determine whether a device is bridged or not. This causes bridge limit to be incorrectly applied or unapplied for hosts with slave devices (e.g. ata_piix).
