* enable interrupts in user path of page fault.Steven Rostedt2007-06-07
| | | | | | | | | | | | | | | | | | | | This is a minor fix, but what is currently there is essentially wrong. In do_page_fault, if the faulting address from user code happens to be in kernel address space (int *p = (int*)-1; p = 0xbed;) then the do_page_fault handler will jump over the local_irq_enable with the goto bad_area_nosemaphore; But the first line there sees this is user code and goes through the process of sending a signal to send SIGSEGV to the user task. This whole time interrupts are disabled and the task can not be preempted by a higher priority task. This patch always enables interrupts in the user path of the bad_area_nosemaphore.

* | Detach sched.h from mm.hAlexey Dobriyan2007-05-21
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | First thing mm.h does is including sched.h solely for can_do_mlock() inline function which has "current" dereference inside. By dealing with can_do_mlock() mm.h can be detached from sched.h which is good. See below, why. This patch a) removes unconditional inclusion of sched.h from mm.h b) makes can_do_mlock() normal function in mm/mlock.c c) exports can_do_mlock() to not break compilation d) adds sched.h inclusions back to files that were getting it indirectly. e) adds less bloated headers to some files (asm/signal.h, jiffies.h) that were getting them indirectly Net result is: a) mm.h users would get less code to open, read, preprocess, parse, ... if they don't need sched.h b) sched.h stops being dependency for significant number of files: on x86_64 allmodconfig touching sched.h results in recompile of 4083 files, after patch it's only 3744 (-8.3%).

* Revert "[PATCH] x86: Drop cc-options call for all options supported in gcc 3.2+"Linus Torvalds2007-05-17
| | | | | | | | | | | | | | | | | This reverts commit c8fdd247255a3a027cd9f66dcf93e6847d1d2f85. It turns out the kernel was correct, and the gcc complaint was a gcc bug. The preferred stack boundary is expressed not in bytes, but in the the log2() of the preferred boundary, so "-mpreferred-stack-boundary=2" is in fact exactly what we want, but a gcc that is compiled for x86-64 will consider it an error (because the 64-bit calling sequence says that the stack should be 16-byte aligned) even if we are then using "-m32" to generate 32-bit code.

Upon frequency change, processor_perflib performs some verification on the frequency (checks that it's within allowable bounds). powernow-k7 deals with absolute frequencies in KHz, whereas perflib only deals with MHz values. When performing the above verification, perflib multiplies the MHz values by 1000 to obtain the KHz value. We then end up with situations like the following: - powernow-k7 multiplies the multiplier by the FSB, and obtains a value such as 1266768 KHz - perflib belives the same state has frequency of 1266 MHz - acpi_processor_ppc_notifier calls cpufreq_verify_within_limits to verify that 1266768 is in the allowable range of 0 to 1266000 (i.e. 1266 * 1000) - it's not, so that frequency is rejected - the maximum CPU frequency is not reachable This patch solves the problem by rounding up the MHz values stored in perflib's tables. Additionally it corrects a broken URL. It also fixes http://bugzilla.kernel.org/show_bug.cgi?id=8255 although this case is a bit different: the frequencies in the _PSS tables are wildly wrong, but we get better results if we force ACPI to respect the fsb * multiplier calculations (even though it seems that the multiplier values aren't entirely correct either).

Entering the kernel at startup_32 without passing our real mode data in %esi, and without guaranteeing that physical and virtual addresses are identity mapped makes head.S impossible to maintain. The only user of this infrastructure is lguest which is not merged so nothing we currently support will break by removing this over designed nightmare, and only the pending lguest patches will be affected. The pending Xen patches have a different entry point that they use. We are currently discussing what Xen and lguest need to do to boot the kernel in a more normal fashion so using startup_32 in this weird manner is clearly not their long term direction.

| | | | | | | | | | | | | | | | | | The definition of USER686 is supposed to be a mask of feature bits, not an OR of feature numbers! It happened to work anyway on the only processor affected, simply by pure coincidence. Fix. Signed-off-by: H. Peter Anvin <hpa@zytor.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

* | Add suspend-related notifications for CPU hotplugRafael J. Wysocki2007-05-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since nonboot CPUs are now disabled after tasks and devices have been frozen and the CPU hotplug infrastructure is used for this purpose, we need special CPU hotplug notifications that will help the CPU-hotplug-aware subsystems distinguish normal CPU hotplug events from CPU hotplug events related to a system-wide suspend or resume operation in progress. This patch introduces such notifications and causes them to be used during suspend and resume transitions. It also changes all of the CPU-hotplug-aware subsystems to take these notifications into consideration (for now they are handled in the same way as the corresponding "normal" ones).

* | Use the APIC to determine the hardware processor id - i386Fernando Luis Vazquez Cao2007-05-09
|/ | | | | | | | | | | | | | | | | | | | | | | hard_smp_processor_id used to be just a macro that hard-coded hard_smp_processor_id to 0 in the non SMP case. When booting non SMP kernels on hardware where the boot ioapic id is not 0 this turns out to be a problem. This is happens frequently in the case of kdump and once in a great while in the case of real hardware. Use the APIC to determine the hardware processor id in both UP and SMP kernels to fix this issue. Notice that hard_smp_processor_id is only used by SMP code or by code that works with apics so we do not need to handle the case when apics are not present and hard_smp_processor_id should never be called there.

* Revert "fbdev: ignore VESA modes if framebuffer is disabled"Linus Torvalds2007-05-08
| | | | | | | | | | | | | | This reverts commit 464bdd33e9baad9806c7adbd8dfc37081a55f27e. Peter Anvin correctly points out that VESA modes have nothing to do with frame buffers per se - they are often just regular extended text modes. Disabling them just because we don't have frame buffer support is very wrong. Cc: H. Peter Anvin <hpa@zytor.com> Cc: Antonino A.
