2009-05-08x86: add a Kconfig symbol for when relocations are neededH. Peter Anvin
We only need to build relocations when we are building a 32-bit relocatable kernel. Rather than unnecessarily complicating the Makefiles, make an explicit Kbuild symbol for this. [ Impact: permits future cleanup ] Signed-off-by: H. Peter Anvin <hpa@zytor.com> Cc: Sam Ravnborg <sam@ravnborg.org>
2009-05-08x86, boot: align the .bss section in the decompressorH. Peter Anvin
Aligning the .bss section makes it trivial to use large operation sizes for moving the initialized sections and clearing the .bss. The alignment chosen (L1 cache) is somewhat arbitrary, but should be large enough to avoid all known performance traps and small enough to not cause troubles.

2009-04-29x86, vmlinux.lds: unify .text output sectionsSam Ravnborg
32 bit x86 had a dedicated .text.head output section, whereas 64 bit had it all in a single output section. In the unified version the dedicated .text.head output section was kept to have full control over the head code. 32 bit: - Moved definition of _stext to the linker script. The definition is located _after_ .text.page_aligned as this is what 32 bit did before. The ALIGN(8) was introduced so we hit the exact same address (on the tested config) before and after the move. I assume that it is a bug that _stext did not cover the .text.page_aligned section - if this is true it can be fixed in a follow-up patch (and the ugly ALIGN() can be dropped).

2009-04-27x86: unify arch/x86/boot/compressed/vmlinux_*.ldsLinus Torvalds
Look at the: diff -u arch/x86/boot/compressed/vmlinux_*.lds output and realize that they're basially exactly the same except for trivial naming differences, and the fact that the 64-bit version has a "pgtable" thing. So unify them. There's some trivial cleanup there (make the output format a Kconfig thing rather than doing #ifdef's for it, and unify both 32-bit and 64-bit BSS end to "_ebss", where 32-bit used to use the traditional "_end"), but other than that it's really very mindless and straigt conversion. For example, I think we should aim to remove "startup_32" vs "startup_64", and just call it "startup", and get rid of one more difference. I didn't do that. Also, notice the comment in the unified vmlinux.lds.S talks about "head_64" and "startup_32" which is an odd and incorrect mix, but that was actually what the old 64-bit only lds file had, so the confusion isn't new, and now that mixing is arguably more accurate thanks to the vmlinux.lds.S file being shared between the two cases ;) [ Impact: cleanup, unification ] Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> Acked-by: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: Ingo Molnar <mingo@elte.hu>

2009-04-15acpi-cpufreq: fix 'smp_call_function_many()' confusionLinus Torvalds
It turns out that 'smp_call_function_many()' doesn't work at all like 'smp_call_function_single()', and my change to Andrew's patch to use it rather than a loop over all CPU's acpi-cpufreq doesn't work. My bad. 'smp_call_function_many()' has two "features" (aka "documented bugs"): (a) it needs to be called with preemption disabled, because it uses smp_processor_id() without guarding the CPU lookup with 'get_cpu()' and 'put_cpu()' like the 'single' variant does. (b) even if the current CPU is part of the CPU mask, it won't do the call on that CPU. Still, we're better off trying to use 'smp_call_function_many()' than looping over CPU's, since it at least in theory allows us to use a broadcast IPI and do it all in parallel. So let's just work around the silly semantic bugs in that function.

2009-04-15powerpc: Fix data-corrupting bug in __futex_atomic_opPaul Mackerras
Richard Henderson pointed out that the powerpc __futex_atomic_op has a bug: it will write the wrong value if the stwcx. fails and it has to retry the lwarx/stwcx. loop, since 'oparg' will have been overwritten by the result from the first time around the loop. This happens because it uses the same register for 'oparg' (an input) as it uses for the result. This fixes it by using separate registers for 'oparg' and 'ret'.

2009-04-15powerpc/pseries: Set error_state to pci_channel_io_normal in eeh_report_reset()Mike Mason
While adding native EEH support to Emulex and Qlogic drivers, it was discovered that dev->error_state was set to pci_io_channel_normal too late in the recovery process. These drivers rely on error_state to determine if they can access the device in their slot_reset callback, thus error_state needs to be set to pci_io_channel_normal in eeh_report_reset(). Below is a detailed explanation (courtesy of Richard Lary) as to why this is necessary. Background: PCI MMIO or DMA accesses to a frozen slot generate additional EEH errors. If the number of additional EEH errors exceeds EEH_MAX_FAILS the adapter will be shutdown. To avoid triggering excessive EEH errors and an undesirable adapter shutdown, some drivers use the pci_channel_offline(dev) wrapper function to return a Boolean value based on the value of pci_dev->error_state to determine if PCI MMIO or DMA accesses are safe. If the wrapper returns TRUE, drivers must not make PCI MMIO or DMA access to their hardware. The pci_dev structure member error_state reflects one of three values, 1) pci_channel_io_normal, 2) pci_channel_io_frozen, 3) pci_channel_io_perm_failure. Function pci_channel_offline(dev) returns TRUE if error_state is pci_channel_io_frozen or pci_channel_io_perm_failure. The EEH driver sets pci_dev->error_state to pci_channel_io_frozen at the point where the PCI slot is frozen. Currently, the EEH driver restores dev->error_state to pci_channel_io_normal in eeh_report_resume() before calling the driver's resume callback. However, when the EEH driver calls the driver's slot_reset callback() from eeh_report_reset(), it incorrectly indicates the error state is still pci_channel_io_frozen. Waiting until eeh_report_resume() to restore dev->error_state to pci_channel_io_normal is too late for Emulex and QLogic FC drivers and any other drivers which are designed to use common code paths in these two cases: i) those called after the driver's slot_reset callback() and ii) those called after the PCI slot is frozen but before the driver's slot_reset callback is called. Case i) all driver paths executed to reinitialize the hardware after a reset and case ii) all code paths executed by driver kernel threads that run asynchronous to the main driver thread, such as interrupt handlers and worker threads to process driver work queues. Emulex and QLogic FC drivers are designed with common code paths which require that pci_channel_offline(dev) reflect the true state of the hardware. The state transitions that the hardware takes from Normal Operations to Slot Frozen to Reset to Normal Operations are documented in the Power Architecture™ Platform Requirements+ (PAPR+) in Table 75. PE State Control. PAPR defines the following 3 states: 0 -- Not reset, Not EEH stopped, MMIO load/store allowed, DMA allowed (Normal Operations) 1 -- Reset, Not EEH stopped, MMIO load/store disabled, DMA disabled 2 -- Not reset, EEH stopped, MMIO load/store disabled, DMA disabled (Slot Frozen) An EEH error places the slot in state 2 (Frozen) and the adapter driver is notified that an EEH error was detected. If the adapter driver returns PCI_ERS_RESULT_NEED_RESET, the EEH driver calls eeh_reset_device() to place the slot into state 1 (Reset) and eeh_reset_device completes by placing the slot into State 0 (Normal Operations). Upon return from eeh_reset_device(), the EEH driver calls eeh_report_reset, which then calls the adapter's slot_reset callback. At the time the adapter's slot_reset callback is called, the true state of the hardware is Normal Operations and should be accurately reflected by setting dev->error_state to pci_channel_io_normal. The current implementation of EEH driver does not do so and requires this change to correct this deficiency.

2009-04-14sh: Pre-allocate a reasonable number of DMA debug entries.Paul Mundt
This prevents the DMA API debugging from running out of entries right away on boot. Defines 4096 entries by default, which while a bit on the heavy side, ought to leave enough breathing room for some time. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2009-04-13Fix quilt merge error in acpi-cpufreq.cLinus Torvalds
We ended up incorrectly using '&cur' instead of '&readin' in the work_on_cpu() -> smp_call_function_single() transformation in commit 01599fca6758d2cd133e78f87426fc851c9ea725 ("cpufreq: use smp_call_function_[single|many]() in acpi-cpufreq.c"). Andrew explains: "OK, the acpi tree went and had conflicting changes merged into it after I'd written the patch and it appears that I incorrectly reverted part of 18b2646fe3babeb40b34a0c1751e0bf5adfdc64c while fixing the resulting rejects. Switching it to `readin' looks correct." Acked-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2009-04-14sh: sh7786: modify usb setup timeout judgment bug.Kuninori Morimoto
This corrects a race with the PHY RST bit not being set properly if the PLL status changes right before timeout. This resulted in it potentially failing even if the device came up in time. Special thanks to Mr. Juha Leppanen and Iwamatsu-san for reporting this out and reviewing it.

2009-04-13Replace all DMA_nBIT_MASK macro with DMA_BIT_MASK(n)Yang Hongyang
This is the second go through of the old DMA_nBIT_MASK macro,and there're not so many of them left,so I put them into one patch.I hope this is the last round. After this the definition of the old DMA_nBIT_MASK macro could be removed.
