The second call to cpu_clear() is redundant, as we've already removed the CPU from cpu_online_map before calling migrate_platform_irqs(). Signed-off-by: Alex Chiang <achiang@hp.com> Signed-off-by: Tony Luck <aegl@agluck-desktop.(none)>

This reverts commit e7b14036. Commit e7b14036 removes the targetted disabled CPU from the cpu_online_map after calls to migrate_platform_irqs and fixup_irqs. Paul McKenney states that the reasoning behind the patch was to prevent irq handlers from running on CPUs marked offline because: RCU happily ignores CPUs that don't have their bits set in cpu_online_map, so if there are RCU read-side critical sections in the irq handlers being run, RCU will ignore them. If the other CPUs were running, they might sequence through the RCU state machine, which could result in data structures being yanked out from under those irq handlers, which in turn could result in oopses or worse. Unfortunately, both ia64 functions above look at cpu_online_map to find a new CPU to migrate interrupts onto. This means we can potentially migrate an interrupt off ourself back to... ourself. Uh oh. This causes an oops when we finally try to process pending interrupts on the CPU we want to disable. The oops results from calling __do_IRQ with a NULL pt_regs: Unable to handle kernel NULL pointer dereference (address 0000000000000040) Call Trace: [<a000000100016930>] show_stack+0x50/0xa0 sp=e0000009c922fa00 bsp=e0000009c92214d0 [<a0000001000171a0>] show_regs+0x820/0x860 sp=e0000009c922fbd0 bsp=e0000009c9221478 [<a00000010003c700>] die+0x1a0/0x2e0 sp=e0000009c922fbd0 bsp=e0000009c9221438 [<a0000001006e92f0>] ia64_do_page_fault+0x950/0xa80 sp=e0000009c922fbd0 bsp=e0000009c92213d8 [<a00000010000c7a0>] ia64_native_leave_kernel+0x0/0x270 sp=e0000009c922fc60 bsp=e0000009c92213d8 [<a0000001000ecdb0>] profile_tick+0xd0/0x1c0 sp=e0000009c922fe30 bsp=e0000009c9221398 [<a00000010003bb90>] timer_interrupt+0x170/0x3e0 sp=e0000009c922fe30 bsp=e0000009c9221330 [<a00000010013a800>] handle_IRQ_event+0x80/0x120 sp=e0000009c922fe30 bsp=e0000009c92212f8 [<a00000010013aa00>] __do_IRQ+0x160/0x4a0 sp=e0000009c922fe30 bsp=e0000009c9221290 [<a000000100012290>] ia64_process_pending_intr+0x2b0/0x360 sp=e0000009c922fe30 bsp=e0000009c9221208 [<a0000001000112d0>] fixup_irqs+0xf0/0x2a0 sp=e0000009c922fe30 bsp=e0000009c92211a8 [<a00000010005bd80>] __cpu_disable+0x140/0x240 sp=e0000009c922fe30 bsp=e0000009c9221168 [<a0000001006c5870>] take_cpu_down+0x50/0xa0 sp=e0000009c922fe30 bsp=e0000009c9221148 [<a000000100122610>] stop_cpu+0xd0/0x200 sp=e0000009c922fe30 bsp=e0000009c92210f0 [<a0000001000e0440>] kthread+0xc0/0x140 sp=e0000009c922fe30 bsp=e0000009c92210c8 [<a000000100014ab0>] kernel_thread_helper+0xd0/0x100 sp=e0000009c922fe30 bsp=e0000009c92210a0 [<a00000010000a4c0>] start_kernel_thread+0x20/0x40 sp=e0000009c922fe30 bsp=e0000009c92210a0 I don't like this revert because it is fragile. ia64 is getting lucky because we seem to only ever process timer interrupts in this path, but if we ever race with an IPI here, we definitely use RCU and have the potential of hitting an oops that Paul describes above. Patching ia64's timer_interrupt() to check for NULL pt_regs is insufficient though, as we still hit the above oops. As a short term solution, I do think that this revert is the right answer. The revert hold up under repeated testing (24+ hour test runs) with this setup: - 8-way rx6600 - randomly toggling CPU online/offline state every 2 seconds - running CPU exercisers, memory hog, disk exercisers, and network stressors - average system load around ~160 In the long term, we really need to figure out why we set pt_regs = NULL in ia64_process_pending_intr(). If it turns out that it is unnecessary to do so, then we could safely re-introduce e7b14036 (along with some other logic to be smarter about migrating interrupts). One final note: x86 also removes the disabled CPU from cpu_online_map and then re-enables interrupts for 1ms, presumably to handle any pending interrupts: arch/x86/kernel/irq_32.c (and irq_64.c): cpu_disable_common: [remove cpu from cpu_online_map] fixup_irqs(): for_each_irq: [break CPU affinities] local_irq_enable(); mdelay(1); local_irq_disable(); So they are doing implicitly what ia64 is doing explicitly.

BTE_MAX_XFER is wrong. It is one greater than the number of cache lines the BTE is actually able to transfer. If you request a transfer of exactly BTE_MAX_XFER size, you trip a very cryptic BUG_ON() which should certainly be made more clear. This patch fixes that constant and also cleans up the BUG_ON()s in arch/ia64/sn/kernel/bte.c to test one condition per line.

Introduced a timing regression: -bash-3.2# time ls real 0m0.006s user 0m1.754s sys 0m1.094s The problem was introduced by an error in cputime_to_timeval.

This reverts commit 7e86c0e6 ("do not overwrite EEPROM on Xonar D2/D2X") because it did not actually help with the problem. More user reports show that the overwriting of the EEPROM is not triggered by using this driver but by installing Linux, and that the installation of any other operating system (even one without any CMI8788 driver) has the same effect. In other words, the presence of this driver does not have any effect on the occurrence of the error. (So far, the available evidence seems to point to a BIOS bug.) Furthermore, it turns out that the EEPROM chip is protected against stray write commands by the command format and by requiring a separate write-enable command, so the error scenario in the previous commit (that SPI writes can be misinterpreted as an EEPROM write command) is not even theoretically possible. The mixer control that was removed as a consequence of the previous commit can only be partially emulated in userspace, which also means it cannot be seen be the in-kernel OSS API emulation, so it is better to revert that change.

Impact: prevent deadlock if ring buffer gets corrupted This patch adds a paranoid check to make sure the ring buffer consumer does not go into an infinite loop. Since the ring buffer has been set to read only, the consumer should not loop for more than the ring buffer size. A check is added to make sure the consumer does not loop more than the ring buffer size. Signed-off-by: Steven Rostedt <srostedt@redhat.com>

Impact: fix output of function tracer to be useful The function tracer is pretty useless if KALLSYMS is not configured.

Impact: fix to prevent hard lockup on self tests If one of the tracers are broken and is constantly filling the ring buffer while the test of the ring buffer is running, it will hang the box. The reason is that the test is a consumer that will not stop till the ring buffer is empty. But if the tracer is broken and is constantly producing input to the buffer, this test will never end. The result is a lockup of the box. This happened when KALLSYMS was not defined and the dynamic ftrace test constantly filled the ring buffer, because the filter failed and all functions were being traced. Something was being called that constantly filled the buffer. Signed-off-by: Steven Rostedt <srostedt@redhat.com>
