[PATCH] hrtimer: round up relative start time on low-res arches

2006-02-15T00:09:35+00:00

CONFIG_TIME_LOW_RES is a temporary way for architectures to signal that
they simply return xtime in do_gettimeoffset().  In this corner-case we
want to round up by resolution when starting a relative timer, to avoid
short timeouts.  This will go away with the GTOD framework.

[PATCH] sys_newfstatat -> sys_fstatat64

2006-02-14T03:58:47+00:00

parisc defines ARCH_WANT_STAT64, so we want to use fstatat64. It does not
appear that it needs to be ENTRY_COMP, because struct stat64 is the same
on both 32-bit and 64-bit (unlike on other platforms which did define a
compat_sys_fstatat64.)

[PARISC] Stub out pselect6/ppoll until TIF_RESTORE_SIGMASK is done

2006-02-09T04:27:58+00:00

Swap out pselect6/ppoll for ni_syscall for now. We also have to switch
the macro to ENTRY_SAME since compat_sys_ni_syscall does not exist.

[PATCH] sys_hpux: fix strlen_user() race

2006-02-08T00:12:33+00:00

Userspace can alter the string after the kernel has run strlen_user().

Also: the strlen_user() return value includes the \0, so fix that.

Also: handle EFAULT from strlen_user().

It's unlikely anyone is using this code.  Very, very unlikely.  If I
remember correctly, CONFIG_HPUX turns this code on, but one would actually
need CONFIG_BINFMT_SOM to load a binary that could cause a problem, and
BINFMT_SOM has had an #error in it for quite some time.

Wire up some new syscalls that have been merged upstream,
  o inotify

[PARISC] Simplify DISCONTIGMEM in Kconfig

2006-01-30T00:33:40+00:00

parisc was previously displaying both the mm/Kconfig memory model
menu, and its own prompt. Remove prompt and have CONFIG_64BIT toggle
between DISCONTIGMEM and FLATMEM. Also remove the EXPERIMENTAL from
discontigmem support... It's been running fine for months (years?)
now.

[PARISC] Arch-specific compat signals

2006-01-23T01:57:42+00:00

Add enough arch-specific compat signals code to enable parisc64
to compile and boot out of the mainline tree. There are likely still
many dragons here, but this is a start to squashing the last
big difference between the mainline tree and the parisc-linux tree.
The remaining bugs can be squashed as they come up.

[PARISC] Use DEBUG_KERNEL to catch used-after-free __init data

2006-01-23T01:26:55+00:00

Use CONFIG_DEBUG_KERNEL to catch kernel code which tries to access
__init data after it is freed. When CONFIG_DEBUG_KERNEL is not set
this also cleans up a WARN_ON at boot time. Also remove some dead
code from mm/init.c

[PARISC] Remove {,un}lock_kernel from perf ioctl

2006-01-23T01:26:52+00:00

Remove the lock_kernel/unlock_kernel pair in the ioctl method. It
plainly wasn't protecting anything.
