For quite a while, there has existed a hypervisor bug on legacy iSeries which means that we do not get the boot time set in the kernel. This patch works around that bug. This was most noticable when the root partition needed to be checked at every boot as the kernel thought it was some time in 1905 until user mode reset the time correctly.

On PPC64, we keep track of when we need to update jiffies (and the variables used to calculate the time of day) based on the time base. If the time base frequence is sufficiently high compared to the processor clock frequency, then it is possible for the time of day variables to be corrupted at the time of the first decrementer interrupt we take. This became obvious on a legacy iSeries where the time base frequency is the same as the processor clock. This one line patch fixes the initialisation so that the time of day variables and the indicator we use to tell when updates are due are better synchronised.

try_to_unmap_cluster() does: for (pte = pte_offset_map(pmd, address); address < end; pte++, address += PAGE_SIZE) { ... } pte_unmap(pte); It may take a little staring to notice, but pte can actually fall off the end of the pte page in this iteration, which makes life difficult for kmap_atomic() and the users not expecting it to BUG(). Of course, we're somewhat lucky in that arithmetic elsewhere in the function guarantees that at least one iteration is made, lest this force larger rearrangements to be made. This issue and patch also apply to non-mm mainline and with trivial adjustments, at least two related kernels. Discovered during internal testing at Oracle.

The netlink gfp_any() problem made me double-check the uses of in_softirq() in crypto/*. It seems to me that we should be checking in_atomic() instead of in_softirq() in crypto_yield.

When we are doing ucopy, we try to defer the ACK generation to cleanup_rbuf(). This works most of the time very well, but if the ucopy prequeue is large, this ACKing behavior kills performance. With TSO, it is possible to fill the prequeue so large that by the time the ACK is sent and gets back to the sender, most of the window has emptied of data and performance suffers significantly. This behavior does help in some cases, so we should think about re-enabling this trick in the future, using some kind of limit in order to avoid the bug case. Signed-off-by: NDavid S. Miller <davem@davemloft.net>

The hardware sync of the timebase on SMP G5s uses a black magic incantation to the i2c clock chip that was inspired from what Darwin does. However, this was an earlier version of Darwin that was ... buggy ! heh. This causes the latest models to break though when starting SMP, so it's worth fixing. Here's a new version of the incantation based on careful transcription of the said incantations as found in the latest version of apple's temple.

The latest speedbumped Apple G5 models have a "bug" in the Open Firmware device tree that lacks the proper interrupt routing information for the northbridge i2c controller. Apple's driver silently falls back into a sub-optimal "polled" mode (heh, maybe they didn't even notice the bug because of that :), our driver didn't properly check and crashes :( This patch fixes our driver to not crash, and adds code to the prom_init() OF trampoline code that detects the "bug" and adds the missing information back for this chipset revision. This fixes booting and thermal control on these models. Signed-off-by: NBenjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by: NLinus Torvalds <torvalds@osdl.org>

I came across the following problem while running ltp-aiodio testcases from ltp-full-20050405 on linux-2.6.12-rc3-mm3. I tried running the tests with EXT3 as well as JFS filesystems. One or two fsx-linux testcases were hung after some time. These testcases were hanging at wait_for_all_aios(). Debugging shows that there were some iocbs which were not getting completed eventhough the last retry for those returned -EIOCBQUEUED. Also all such pending iocbs represented READ operation. Further debugging revealed that all such iocbs hit EOF in the DIO layer. To be more precise, the "pos" from which they were trying to read was greater than the "size" of the file. So the generic_file_direct_IO returned 0. This happens rarely as there is already a check in __generic_file_aio_read(), for whether "pos" < "size" before calling direct IO routine. >size = i_size_read(inode); >if (pos < size) { > retval = generic_file_direct_IO(READ, iocb, > iov, pos, nr_segs); But for READ, we are taking the inode->i_sem only in the DIO layer. So it is possible that some other process can change the size of the file before we take the i_sem. In such a case ( when "pos" > "size"), the __generic_file_aio_read() would return -EIOCBQUEUED even though there were no I/O requests submitted by the DIO layer. This would cause the AIO layer to expect aio_complete() for THE iocb, which doesnot happen. And thus the test hangs forever, waiting for an I/O completion, where there are no requests submitted at all. The following patch makes __generic_file_aio_read() return 0 (instead of returning -EIOCBQUEUED), on getting 0 from generic_file_direct_IO(), so that the AIO layer does the aio_complete(). Testing: I have tested the patch on a SMP machine(with 2 Pentium 4 (HT)) running linux-2.6.12-rc3-mm3. I ran the ltp-aiodio testcases and none of the fsx-linux tests hung. Also the aio-stress tests ran without any problem.

In _spin_unlock_bh(lock): do { \ _raw_spin_unlock(lock); \ preempt_enable(); \ local_bh_enable(); \ __release(lock); \ } while (0) there is no reason for using preempt_enable() instead of a simple preempt_enable_no_resched() Since we know bottom halves are disabled, preempt_schedule() will always return at once (preempt_count!=0), and hence preempt_check_resched() is useless here... This fixes it by using "preempt_enable_no_resched()" instead of the "preempt_enable()", and thus avoids the useless preempt_check_resched() just before re-enabling bottom halves.

The test case at http://cvs.sourceforge.net/viewcvs.py/posixtest/posixtestsuite/conforman ce/interfaces/clock_nanosleep/1-5.c fails if it runs as a 32bit process on x86_86 machines. The root cause is the sub 32bit process fails to restart the syscall after it is interrupted by a signal. The syscall number of sys_restart_syscall in table sys_call_table is __NR_restart_syscall (219) while it's __NR_ia32_restart_syscall (0) in ia32_sys_call_table. When regs->rax==(unsigned long)-ERESTART_RESTARTBLOCK, function do_signal doesn't distinguish if the process is 64bit or 32bit, and always sets restart syscall number as __NR_restart_syscall (219).
