* [PATCH] convert that currently tests _NSIG directly to use valid_signal()Jesper Juhl2005-05-011-2/+2
| | | | | | | | | Convert most of the current code that uses _NSIG directly to instead use valid_signal(). This avoids gcc -W warnings and off-by-one errors. Signed-off-by: Jesper Juhl <juhl-lkml@dif.dk> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

* [PATCH] misc verify_area cleanupsJesper Juhl2005-05-012-2/+2
| | | | | | | | | | | | | | | | | | There were still a few comments left refering to verify_area, and two functions, verify_area_skas & verify_area_tt that just wrap corresponding access_ok_skas & access_ok_tt functions, just like verify_area does for access_ok - deprecate those. There was also a few places that still used verify_area in commented-out code, fix those up to use access_ok. After applying this one there should not be anything left but finally removing verify_area completely, which will happen after a kernel release or two.

* [PATCH] uml ubd: handle readonly statusPaolo 'Blaisorblade' Giarrusso2005-05-011-4/+10
| | | | | | | | | | | | | | | | Use the set_disk_ro() API when the backing file is read-only, to mark the disk read-only, during the ->open(). The current hack does not work when doing a mount -o remount. Also, mark explicitly the code paths which should no more be triggerable (I've removed the WARN_ON(1) things). They should actually become BUG()s probably but I'll avoid that since I'm not so sure the change works so well. I gave it only some limited testing.

| | | | | | | | | Fix some console locking problems (including scheduling in atomic) and various reorderings and cleanup in that code. Not yet ready for 2.6.12 probably.

* [PATCH] uml: fix syscall table by including $(SUBARCH)'s one, for x86-64Paolo 'Blaisorblade' Giarrusso2005-05-015-318/+73
| | | | | | | | | | | | | | | | | | Reuse asm-x86-64/unistd.h to build our syscall table, like x86-64 already does. Like for i386, we must add some #defines for all the (right!) changes UML does to x86-64 syscall table. Note: I noted a bogus: [ __NR_sched_yield ] = (syscall_handler_t *) yield, while doing this patch (which could only be a workaround for some strange bug, but I would ignore this possibility). I'm changing this without notice. Signed-off-by: Paolo 'Blaisorblade' Giarrusso <blaisorblade@yahoo.it> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
* [PATCH] uml: quick fix syscall table for x86_64Paolo 'Blaisorblade' Giarrusso2005-05-011-29/+24
| | | | | | | | | | | | | | | | | | Fix the moved syscall table for the x86_64 SUBARCH: - redirect __NR_chown and such to versions aware of 32-bit UIDs, - avoid the useless hack for sys_nfsservctl, - use sys_sendfile64 in the table rather than sys_sendfile. - __NR_uselib is sys_ni_syscall on x86_64 (which does not support A.OUT). - __NR_getrlimit is sys_getrlimit, not sys_old_getrlimit Signed-off-by: Paolo 'Blaisorblade' Giarrusso <blaisorblade@yahoo.it> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
* [PATCH] uml: fix syscall table by including $(SUBARCH)'s one, for i386Paolo 'Blaisorblade' Giarrusso2005-05-017-116/+29
| | | | | | | | | | | | | | | | Split the i386 entry.S files into entry.S and syscall_table.S which is included in the previous one (so actually there is no difference between them) and use the syscall_table.S in the UML build, instead of tracking by hand the syscall table changes (which is inherently error-prone). We must only insert the right #defines to inject the changes we need from the i386 syscall table (for instance some different function names); also, we don't implement some i386 syscalls, as ioperm(), nor some TLS-related ones (yet to provide).

* [PATCH] uml: move va_copy conditional defPaolo 'Blaisorblade' Giarrusso2005-05-011-2/+2
| | | | | | | | | | GCC 2.95 uses __va_copy instead of va_copy. Handle it inside compiler.h instead of in a casual file, and avoid the risk that this breaks with a newer compiler (which it could do).

* [PATCH] uml: support AES i586 crypto driverPaolo 'Blaisorblade' Giarrusso2005-05-015-8/+17
| | | | | | | | | | | | | | | | | | | | We want to make possible, for the user, to enable the i586 AES implementation. This requires a restructure. - Add a CONFIG_UML_X86 to notify that we are building a UML for i386. - Rename CONFIG_64_BIT to CONFIG_64BIT as is used for all other archs - Tell crypto/Kconfig that UML_X86 is as good as X86 - Tell it that it must exclude not X86_64 but 64BIT, which will give the same results. - Tell kbuild to descend down into arch/i386/crypto/ to build what's needed.

* [PATCH] uml: workaround old problematic sed behaviourRob Landley2005-05-011-1/+2
| | | | | | | | | | | | | Old versions of sed from 1998 (predating the first release of gcc 2.95, but still in use by debian stable) don't understand the single-line version of the sed append command. Since newer versions of sed still understand the... ahem, "vintage" form of the command, change our code to use that.

* [PATCH] uml: add nfsd syscall when nfsd is modularblaisorblade@yahoo.it2005-05-011-7/+1
| | | | | | | | | | | | This trick is useless, because sys_ni.c will handle this problem by itself, like it does even on UML for other syscalls. Also, it does not provide the NFSD syscall when NFSD is compiled as a module, which is a big problem.

* Linux-2.6.12-rc2Linus Torvalds2005-04-16295-0/+35908
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
