* [SPARC]: Fix section mismatch warnings in pci.c and pcic.cRobert Reif2007-04-121-2/+2

* [SPARC]: avoid CHILD_MAX and OPEN_MAX constantsRoland McGrath2007-04-121-2/+2
| | | | | | | | | | | | | | | | I don't figure anyone really cares about SunOS syscall emulation, and I certainly don't. But I'm getting rid of uses of the OPEN_MAX and CHILD_MAX compile-time constant, and these are almost the only ones. OPEN_MAX is a bogus constant with no meaning about anything. The RLIMIT_NOFILE resource limit is what sysconf (_SC_OPEN_MAX) actually wants to return. The CHILD_MAX cases weren't actually using anything I want to get rid of, but I noticed that they are there and are wrong too. The CHILD_MAX value is not really unlimited as a -1 return from sysconf indicates. The RLIMIT_NPROC resource limit is what sysconf (_SC_CHILD_MAX) wants to return.

* [SPARC]: Fix bus handling in build_device_resources().David S. Miller2007-03-021-3/+4
| | | | | | | | | | | | | | We mistakedly modify 'bus' in the innermost loop. What should happen is that at each register index iteration, we start with the same 'bus'. So preserve it's value at the top level, and use a loop local variable 'dbus' for iteration. This bug causes registers other than the first to be decoded improperly. Signed-off-by: David S.

* [SPARC]: Re-export saved_command_line to modules.David S. Miller2007-02-121-1/+1
| | | | | | | | | | | | | This reverts some bogosity from the dynamic command-line changes made on sparc32 and sparc64. Drivers such as drivers/sbus/char/openprom.c reference saved_command_line, and can be modular. The boot_command_line is __initdata, yet the dynamic command-line changes add modular exports of that symbol, obviously wrong. Signed-off-by: David S. Miller <davem@davemloft.net>
* [PATCH] mark struct file_operations const 2Arjan van de Ven2007-02-121-1/+1
| | | | | | | | | | | | Many struct file_operations in the kernel can be "const". Marking them const moves these to the .rodata section, which avoids false sharing with potential dirty data.

* [PATCH] signal: use kill_pgrp not kill_pg in the sunos compatibility codeEric W. Biederman2007-02-121-4/+6
| | | | | | | | | | | | | | I am slowly moving to a model where all process killing is struct pid based instead of pid_t based. The sunos compatibility code is one of the last users of the old pid_t based kill_pg in the kernel. By being complete I allow for the future removal of kill_pg from the kernel, which will ensure I don't miss something. Signed-off-by: Eric W.

* [PATCH] consolidate line discipline number definitionsTilman Schmidt2007-02-111-0/+1
| | | | | | | | | | | | | | | | | | | The line discipline numbers N_* are currently defined for each architecture individually, but (except for a seeming mistake) identically, in asm/termios.h. There is no obvious reason why these numbers should be architecture specific, nor any apparent relationship with the termios structure. The total number of these, NR_LDISCS, is defined in linux/tty.h anyway. So I propose the following patch which moves the definitions of the individual line disciplines to linux/tty.h too. Three of these numbers (N_MASC, N_PROFIBUS_FDL, and N_SMSBLOCK) are unused in the current kernel, but the patch still keeps the complete set in case there are plans to use them yet.

However, sparc vmlinux has plenty of relocatable sections because it is being built with 'ld -r' (to allow for btfixup processing). So for sparc, modpost does do a lot of checking. Sure enough, running modpost on arch/sparc/boot/image yields no output (i.e. all is well). modpost.c check_sec_ref() has: /* We want to process only relocation sections and not .init */ if (sechdrs[i].sh_type == SHT_RELA) { // check here } else if (sechdrs[i].sh_type == SHT_REL) { // check here } Signed-off-by: Martin Habets <errandir_news@mph.eclipse.co.uk> Signed-off-by: David S.

* [PATCH] VFS: Make filldir_t and struct kstat deal in 64-bit inode numbersDavid Howells2006-10-031-4/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | These patches make the kernel pass 64-bit inode numbers internally when communicating to userspace, even on a 32-bit system. They are required because some filesystems have intrinsic 64-bit inode numbers: NFS3+ and XFS for example. The 64-bit inode numbers are then propagated to userspace automatically where the arch supports it. Problems have been seen with userspace (eg: ld.so) using the 64-bit inode number returned by stat64() or getdents64() to differentiate files, and failing because the 64-bit inode number space was compressed to 32-bits, and so overlaps occur. This patch: Make filldir_t take a 64-bit inode number and struct kstat carry a 64-bit inode number so that 64-bit inode numbers can be passed back to userspace. The stat functions then returns the full 64-bit inode number where available and where possible. If it is not possible to represent the inode number supplied by the filesystem in the field provided by userspace, then error EOVERFLOW will be issued. Similarly, the getdents/readdir functions now pass the full 64-bit inode number to userspace where possible, returning EOVERFLOW instead when a directory entry is encountered that can't be properly represented. Note that this means that some inodes will not be stat'able on a 32-bit system with old libraries where they were before - but it does mean that there will be no ambiguity over what a 32-bit inode number refers to. Note similarly that directory scans may be cut short with an error on a 32-bit system with old libraries where the scan would work before for the same reasons. It is judged unlikely that this situation will occur because modern glibc uses 64-bit capable versions of stat and getdents class functions exclusively, and that older systems are unlikely to encounter unrepresentable inode numbers anyway.

* [PATCH] provide kernel_execve on all architecturesArnd Bergmann2006-10-021-0/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds the new kernel_execve function on all architectures that were using _syscall3() to implement execve. The implementation uses code from the _syscall3 macros provided in the unistd.h header file. I don't have cross-compilers for any of these architectures, so the patch is untested with the exception of i386. Most architectures can probably implement this in a nicer way in assembly or by combining it with the sys_execve implementation itself, but this should do it for now.

* [PATCH] namespaces: add nsproxySerge E. Hallyn2006-10-021-0/+2
| | | | | | | | | | | | | | | | | | | This patch adds a nsproxy structure to the task struct. Later patches will move the fs namespace pointer into this structure, and introduce a new utsname namespace into the nsproxy. The vserver and openvz functionality, then, would be implemented in large part by virtualizing/isolating more and more resources into namespaces, each contained in the nsproxy.

* [PATCH] kill wall_jiffiesAtsushi Nemoto2006-10-012-29/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With 2.6.18-rc4-mm2, now wall_jiffies will always be the same as jiffies. So we can kill wall_jiffies completely. This is just a cleanup and logically should not change any real behavior except for one thing: RTC updating code in (old) ppc and xtensa use a condition "jiffies - wall_jiffies == 1". This condition is never met so I suppose it is just a bug. I just remove that condition only instead of kill the whole "if" block.

* [PATCH] simplify update_times (avoid jiffies/jiffies_64 aliasing problem)Atsushi Nemoto2006-09-292-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Pass ticks to do_timer() and update_times(), and adjust x86_64 and s390 timer interrupt handler with this change. Currently update_times() calculates ticks by "jiffies - wall_jiffies", but callers of do_timer() should know how many ticks to update. Passing ticks get rid of this redundant calculation. Also there are another redundancy pointed out by Martin Schwidefsky. This cleanup make a barrier added by 5aee405c662ca644980c184774277fc6d0769a84 needless. So this patch removes it. As a bonus, this cleanup make wall_jiffies can be removed easily, since now wall_jiffies is always synced with jiffies. (This patch does not really remove wall_jiffies. It would be another cleanup patch) Signed-off-by: Atsushi Nemoto <anemo@mba.ocn.ne.jp> Cc: Martin Schwidefsky <schwidefsky@de.ibm.com> Cc: "Eric W.
