* Introduce compat_u64 and compat_s64 typesArnd Bergmann2007-07-161-0/+2
| | | | | | | | | | | | | | | | | | | | | | One common problem with 32 bit system call and ioctl emulation is the different alignment rules between i386 and 64 bit machines. A number of drivers work around this by marking the compat structures as 'attribute((packed))', which is not the right solution because it breaks all the non-x86 architectures that want to use the same compat code. Hopefully, this patch improves the situation, it introduces two new types, compat_u64 and compat_s64. These are defined on all architectures to have the same size and alignment as the 32 bit version of u64 and s64. Signed-off-by: Arnd Bergmann <arnd@arndb.de> Acked-by: David S.

* wrap access to thread_infoRoman Zippel2007-05-091-1/+1
| | | | | | | | | Recently a few direct accesses to the thread_info in the task structure snuck back, so this wraps them with the appropriate wrapper.

* [PARISC] Switch is_compat_task to use TIF_32BITKyle McMartin2006-10-041-2/+2
| | | | | | | | Stop using PER_LINUX32 to designate processes needing compaterizing. Convert is_compat_task to use TIF_32BIT and set TIF_32BIT in binfmt_elf32.c Signed-off-by: Kyle McMartin <kyle@parisc-linux.org>

* [PATCH] compat: be more consistent about [ug]id_tStephen Rothwell2005-09-071-4/+6
| | | | | | | | | | | | | | | | | | | | 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.

* [PATCH] compat: introduce compat_time_tStephen Rothwell2005-06-231-1/+1
| | | | | | | | | | This patch is based on work by Carlos O'Donell and Matthew Wilcox. It introduces/updates the compat_time_t type and uses it for compat siginfo structures. I have built this on ppc64 and x86_64. Signed-off-by: Stephen Rothwell <sfr@canb.auug.org.au> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
* Linux-2.6.12-rc2Linus Torvalds2005-04-161-0/+145
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!
