* [PATCH] kill __init_timer_base in favor of boot_tvec_basesOleg Nesterov2006-03-31
| | | | | | | | | | | | | Commit a4a6198b80cf82eb8160603c98da218d1bd5e104: [PATCH] tvec_bases too large for per-cpu data introduced "struct tvec_t_base_s boot_tvec_bases" which is visible at compile time. This means we can kill __init_timer_base and move timer_base_s's content into tvec_t_base_s.

* [PATCH] Mark unwind info for signal trampolines in vDSOsJakub Jelinek2006-03-31
| | | | | | | | | | | | | | | | | | Mark unwind info for signal trampolines using the new S augmentation flag introduced in: http://gcc.gnu.org/PR26208. GCC 4.2 (or patched earlier GCC) will be able to special case unwinding through frames right above signal trampolines. As the augmentations start with z flag and S is at the very end of the augmentation string, older GCCs will just skip the S flag as unknown (that's why an augmentation flag was chosen over say a new CFA opcode).

* [PATCH] for_each_possible_cpu: s390KAMEZAWA Hiroyuki2006-03-31
| | | | | | | | | | | | | | | | | | for_each_cpu() actually iterates across all possible CPUs. We've had mistakes in the past where people were using for_each_cpu() where they should have been iterating across only online or present CPUs. This is inefficient and possibly buggy. We're renaming for_each_cpu() to for_each_possible_cpu() to avoid this in the future. This patch replaces for_each_cpu with for_each_possible_cpu.

* [PATCH] uml: check for differences in host supportPaolo 'Blaisorblade' Giarrusso2006-03-31
| | | | | | | | | | | | | | | | | | If running on a host not supporting TLS (for instance 2.4) we should report that cleanly to the user, instead of printing not comprehensible "error 5" for that. Additionally, i386 and x86_64 support different ranges for user_desc->entry_number, and we must account for that; we couldn't pass ourselves -1 because we need to override previously existing TLS descriptors which glibc has possibly set, so test at startup the range to use. x86 and x86_64 existing ranges are hardcoded.

* [PATCH] uml: implement {get,set}_thread_area for i386Paolo 'Blaisorblade' Giarrusso2006-03-31
| | | | | | | | | | | | | | | | | | | | | | Implement sys_[gs]et_thread_area and the corresponding ptrace operations for UML. This is the main chunk, additional parts follow. This implementation is now well tested and has run reliably for some time, and we've understood all the previously existing problems. Their implementation saves the new GDT content and then forwards the call to the host when appropriate, i.e. immediately when the target process is running or on context switch otherwise (i.e. on fork and on ptrace() calls). In SKAS mode, we must switch registers on each context switch (because SKAS does not switches tls_array together with current->mm). Also, added get_cpu() locking; this has been done for SKAS mode, since TT does not need it (it does not use smp_processor_id()).

* [PATCH] uml: clean arch_switch usagePaolo 'Blaisorblade' Giarrusso2006-03-31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Call arch_switch also in switch_to_skas, even if it's, for now, a no-op for that case (and mark this in the comment); this will change soon. Also, arch_switch for TT mode is actually useless when the PT proxy (a complicate debugging instrumentation for TT mode) is not enabled. In fact, it only calls update_debugregs, which checks debugregs_seq against seq (to check if the registers are up-to-date - seq here means a "version number" of the registers). If the ptrace proxy is not enabled, debugregs_seq always stays 0 and update_debugregs will be a no-op. So, optimize this out (the compiler can't do it). Also, I've been disappointed by the fact that it would make a lot of sense if, after calling a successful update_debugregs(current->thread.arch.debugregs_seq), current->thread.arch.debugregs_seq were updated with the new debugregs_seq. But this is not done. Is this a bug or a feature? For all purposes, it seems a bug (otherwise the whole mechanism does not make sense, which is also a possibility to check), which causes some performance only problems (not correctness), since we write_debugregs when not needed. Also, as suggested by Jeff, remove a redundant enabling of SIGVTALRM, comprised in the subsequent local_irq_enable(). I'm just a bit dubious if ordering matters there...

* [PATCH] uml: split ldt.h in arch-independent and arch-dependant codePaolo 'Blaisorblade' Giarrusso2006-03-31
| | | | | | | | | | | | | | | | | | | | ldt-{i386,x86_64}.h is made of two different parts - some code for parsing of LDT descriptors, which is arch-dependant, and the code to handle uml_ldt_t (an LDT block inside UML), which is mostly arch-independant (among x86 and x86_64, at least). Join the common part in a single file (ldt.h) and split the rest away (host_ldt-{i386,x86_64}.h). This is needed because processor.h, with next patches, will start including the LDT descriptor parsing macros in host_ldt.h, but it can't include ldt.h because it uses semaphores (and to define semaphores one must first include processor.h!).

| | | | | | | | | | | | | | | Comparing this code which is the actual body of the arch-independent cpu_idle(), it is clear that it's unnecessary to set ->mm and ->active_mm; beyond that, a kernel thread is not supposed to have ->mm != NULL, only active_mm. This showed up because I used the assumption (which is IMHO valid) that kernel thread have their ->mm == NULL, and it failed for this thread.

* [PATCH] UML: Hotplug memory, take 2Jeff Dike2006-03-31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Changes since first version added check for MADV_REMOVE support on the host fixed error return botch shrunk sprintf array by one character This adds hotplug memory support to UML. The mconsole syntax is config mem=[+-]n[KMG] In other words, add or subtract some number of kilobytes, megabytes, or gigabytes. Unplugged pages are allocated and then madvise(MADV_TRUNCATE), which is a currently experimental madvise extension. These pages are tracked so they can be plugged back in later if the admin decides to give them back. The first page to be unplugged is used to keep track of about 4M of other pages. A list_head is the first thing on this page. The rest is filled with addresses of other unplugged pages. This first page is not madvised, obviously. When this page is filled, the next page is used in a similar way and linked onto a list with the first page. Etc. This whole process reverses when pages are plugged back in. When a tracking page no longer tracks any unplugged pages, then it is next in line for plugging, which is done by freeing pages back to the kernel.

* [PATCH] i386 kdump timer vector lockup fixVivek Goyal2006-03-31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Porting the patch I posted for x86_64 to i386. http://marc.theaimsgroup.com/?l=linux-kernel&m=114178139610707&w=2 o While using kdump, after a system crash when second kernel boots, timer vector gets (0x31) locked and CPU does not see timer interrupts travelling from IOAPIC to APIC. Currently it does not lead to boot failure in second kernel as timer interrupts continues to come as ExtInt through LAPIC directly, but fixing it is good in case some boards do not support the other mode. o After a system crash, it is not safe to service interrupts any more, hence interrupts are disabled. This leads to pending interrupts at LAPIC. LAPIC sends these interrupts to the CPU during early boot of second kernel. Other pending interrupts are discarded saying unexpected trap but timer interrupt is serviced and CPU does not issue an LAPIC EOI because it think this interrupt came from i8259 and sends ack to 8259. This leads to vector 0x31 locking as LAPIC does not clear respective ISR and keeps on waiting for EOI. o This patch issues extra EOI for the pending interrupts who have ISR set. o Though today only timer seems to be the special case because in early boot it thinks interrupts are coming from i8259 and uses mask_and_ack_8259A() as ack handler and does not issue LAPIC EOI. But probably doing it in generic manner for all vectors makes sense. Signed-off-by: Vivek Goyal <vgoyal@in.ibm.com> Cc: "Eric W.

* [PATCH] MTD_NAND_SHARPSL and MTD_NAND_NANDSIM should be tristate'sAdrian Bunk2006-03-31
| | | | | | | | | | | | | | | | | | MTD_NAND=m and MTD_NAND_SHARPSL=y or MTD_NAND_NANDSIM=y are illegal combinations that mustn't be allowed. This patch fixes this bug by making MTD_NAND_SHARPSL and MTD_NAND_NANDSIM tristate's. Additionally, it fixes some whitespace damage at these options.
