This patch stops CompactFlash devices being marked as removable. They are
not removable (as defined by Linux) as the media and device are
inseparable. When a card is removed, the whole device is removed from the
system and never sits in a media-less state.
This stops some nasty udev device creation/destruction loops.
Further, once this change is made, there is no need for ide to can be
removed from ide_drive_t.

There's no reason MAX_HWIFS needs to be ia64-specific, so set MAX_HWIFS
from CONFIG_IDE_MAX_HWIFS.
This reduces the default from 10 to 4, but I don't think that's a problem.

Change locking in the new tty buffering facility from using tty->read_lock,
which is currently ignored by drivers and thus ineffective. New locking
uses a new tty buffering specific lock enforced centrally in the tty
buffering code.
Two drivers (esp and cyclades) are updated to use the tty buffering
functions instead of accessing tty buffering internals directly. This is
required for the new locking to work.
Minor checks for NULL buffers added to

The patch implements cpu topology exportation by sysfs.
Items (attributes) are similar to /proc/cpuinfo.
1) /sys/devices/system/cpu/cpuX/topology/physical_package_id:
represent the physical package id of cpu X;
2) /sys/devices/system/cpu/cpuX/topology/core_id:
represent the cpu core id to cpu X;
3) /sys/devices/system/cpu/cpuX/topology/thread_siblings:
represent the thread siblings to cpu X in the same core;
4) /sys/devices/system/cpu/cpuX/topology/core_siblings:
represent the thread siblings to cpu X in the same physical package;
To implement it in an architecture-neutral way, a new source file,
driver/base/topology.c, is to export the 5 attributes.
If one architecture wants to support this feature, it just needs to
implement 4 defines, typically in file include/asm-XXX/topology.h.
The 4 defines are:
#define topology_physical_package_id(cpu)
#define topology_core_id(cpu)
#define topology_thread_siblings(cpu)
#define topology_core_siblings(cpu)
The type of **_id is int.
The type of siblings is cpumask_t.
To be consistent on all architectures, the 4 attributes should have
deafult values if their values are unavailable. Below is the rule.
1) physical_package_id: If cpu has no physical package id, -1 is the
default value.
2) core_id: If cpu doesn't support multi-core, its core id is 0.
3) thread_siblings: Just include itself, if the cpu doesn't support
HT/multi-thread.
4) core_siblings: Just include itself, if the cpu doesn't support
multi-core and HT/Multi-thread.
So be careful when declaring the 4 defines in include/asm-XXX/topology.h.
If an attribute isn't defined on an architecture, it won't be exported.
Thank Nathan, Greg, Andi, Paul and Venki.
The patch provides defines for i386/x86_64/ia64.

This fixes the code like this:
bh = sb_find_get_block (sb, tmp + j);
if ((bh && DATA_BUFFER_USED(bh)) || tmp != fs32_to_cpu(sb, *p)) {
retry = 1;
brelse (bh);
goto next1;
}
bforget (bh);
sb_find_get_block() ordinarily returns a buffer_head with b_count>=2, and
this code assume that in case if "b_count>1" buffer is used, so this caused
infinite loop.
(akpm: that is-the-buffer-busy code is incomprehensible. Good riddance. Use
of block_truncate_page() seems sane).

"rm" command, on file system with "ufs1" type cause system hang up. This
is, in fact, not so bad as it seems to be, because of after that in "kernel
control path" there are 3-4 places which may cause "oops".
So the first patch fix oopses, and the second patch fix "kernel hang up".
"oops" appears because of reading of group's summary info partly wrong, and
access to not first group's summary info cause "oops".

Most of the 64 bit architectures will zero extend the first argument to
compat_sys_{openat,newfstatat,futimesat} which will fail if the 32 bit
syscall was passed AT_FDCWD (which is a small negative number). Declare
the first argument to be an unsigned int which will force the correct
sign extension when the internal functions are called in each case.
Also, do some small white space cleanups in fs/compat.c.

This fixes a bug whereby if two processes try to look up the same auth_gss
credential, they may end up creating two creds, and triggering two upcalls
because the upcall is performed before the credential is added to the
credcache.
Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
|

When we look up a new cred in the auth_gss downcall so that we can stuff
the credcache, we do not want that lookup to queue up an upcall in order
to initialise it. To do an upcall here not only redundant, but since we
are already holding the inode->i_mutex, it will trigger a lock recursion.
This patch allows rpcauth cache searches to indicate that they can cope
with uninitialised credentials.

Olaf reported UML doesn't build for him with a clear analisys of what happened
- we're using NR_CPUS in files linked against glibc headers. Seems like it
defines CONFIG_SMP but not CONFIG_NR_CPUS, so we get CONFIG_NR_CPUS
undeclared.
The fix is to move the declaration away from that header file and move it in
asm-um headers, and to add that header where needed.

Enable selection of different user/kernel VM splits for i386, including an
optimized mode for 1GB physical RAM, which gives the kernel a direct (non
HIGHMEM) mapping to the entire 1GB rather than just the first 896MB.
There is a similarly a similarly optimized mode for machines with exactly 2GB
of physical RAM.
This can speed up the kernel by avoiding having to create/destroy temporary
HIGHMEM mappings, and by not having to include HIGHMEM support at all on such
machines. The flip side is that there's less virtual addressing left for
userspace in these alternatives, and some binary-only kernel modules may
misbehave unless rebuilt with the same VMSPLIT option as the main kernel
image.
