* [PATCH] Add epoll compat_ code to fs/compat.cDavide Libenzi2007-03-08
| | | | | | | | | | | | | | | | | | | | | | | | IA64 and ARM-OABI are currently using their own version of epoll compat_ code. An architecture needs epoll_event translation if alignof(u64) in 32 bit mode is different from alignof(u64) in 64 bit mode. If an architecture needs epoll_event translation, it must define struct compat_epoll_event in asm/compat.h and set CONFIG_HAVE_COMPAT_EPOLL_EVENT and use compat_sys_epoll_ctl and compat_sys_epoll_wait. All 64 bit architecture should use compat_sys_epoll_pwait. [sfr: restructure and move to fs/compat.c, remove MIPS version of compat_sys_epoll_pwait, use __put_user_unaligned] Signed-off-by: Stephen Rothwell <sfr@canb.auug.org.au> Cc: David Woodhouse <dwmw2@infradead.org> Cc: Russell King <rmk@arm.linux.org.uk> Cc: "Luck, Tony" <tony.luck@intel.com> Cc: "David S.

* Add prototype for sigset_from_compat()Linus Torvalds2006-10-02
| | | | | | | | | | Duh. I screwed up editing David Howells patch in commit 3f2e05e90e0846c42626e3d272454f26be34a1bc, and the actual declaration for the sigset_from_compat() function went missing. My bad. Olaf Hering saved the day and noticed that I'm a moron. Signed-off-by: Linus Torvalds <torvalds@osdl.org>
* [PATCH] BLOCK: Revert patch to hack around undeclared sigset_t in linux/compat.hDavid Howells2006-10-02
| | | | | | | | | | | | | | | | Revert Andrew Morton's patch to temporarily hack around the lack of a declaration of sigset_t in linux/compat.h to make the block-disablement patches build on IA64. This got accidentally pushed to Linus and should be fixed in a different manner. Also make linux/compat.h #include asm/signal.h to gain a definition of sigset_t so that it can externally declare sigset_from_compat(). This has been compile-tested for i386, x86_64, ia64, mips, mips64, frv, ppc and ppc64 and run-tested on frv.

* [PATCH] x86_64: Add compat_printk and sysctl to turn off compat layer warningsAndi Kleen2006-06-26
| | | | | | | | | Sometimes e.g. with crashme the compat layer warnings can be noisy. Add a way to turn them off by gating all output through compat_printk that checks a global sysctl. The default is not changed. Signed-off-by: Andi Kleen <ak@suse.de> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

* [PATCH] select: fix returned timevalAndrew Morton2006-02-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With David Woodhouse <dwmw2@infradead.org> select() presently has a habit of increasing the value of the user's `timeout' argument on return. We were writing back a timeout larger than the original. We _deliberately_ round up, since we know we must wait at _least_ as long as the caller asks us to. The patch adds a couple of helper functions for magnitude comparison of timespecs and of timevals, and uses them to prevent the various poll and select functions from returning a timeout which is larger than the one which was passed in. The patch also fixes a bug in compat_sys_pselect7(): it was adding the new timeout value to the old one and was returning that. It should just return the new timeout value. (We have various handy timespec/timeval-to-from-nsec conversion functions in time.h. But this code open-codes it all). Cc: "David S.

* [PATCH] compat: be more consistent about [ug]id_tStephen Rothwell2005-09-07
| | | | | | | | | | | | | | | | | | | | When I first wrote the compat layer patches, I was somewhat cavalier about the definition of compat_uid_t and compat_gid_t (or maybe I just misunderstood :-)). This patch makes the compat types much more consistent with the types we are being compatible with and hopefully will fix a few bugs along the way. compat type type in compat arch __compat_[ug]id_t __kernel_[ug]id_t __compat_[ug]id32_t __kernel_[ug]id32_t compat_[ug]id_t [ug]id_t The difference is that compat_uid_t is always 32 bits (for the archs we care about) but __compat_uid_t may be 16 bits on some.

* Linux-2.6.12-rc2v2.6.12-rc2Linus Torvalds2005-04-16
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!
