Jesper Juhl d52988023a Remove the last few UMSDOS leftovers
The UMSDOS filesystem was removed back in 2.6.11, but some tiny bits stuck
around.  This patch removes the few remaining leftovers.  The only things
left behind after this are the entries in the CREDITS file and the ioctl
number in Documentation/ioctl-number.txt as documentation.

This third (hopefully final) version of the patch doesn't edit the
arch/um/config.release file, since Jeff Dike pointed out to me that it
should die completely, and asked me to remove it from my patch as he'll
send in a seperate patch removing the file completely.

Heiko Carstens 608e261968 generic bug: use show_regs() instead of dump_stack()
The current generic bug implementation has a call to dump_stack() in case a
WARN_ON(whatever) gets hit.  Since report_bug(), which calls dump_stack(),
gets called from an exception handler we can do better: just pass the
pt_regs structure to report_bug() and pass it to show_regs() in case of a
warning.  This will give more debug informations like register contents,
etc...  In addition this avoids some pointless lines that dump_stack()
emits, since it includes a stack backtrace of the exception handler which
is of no interest in case of a warning.  E.g.  on s390 the following lines
are currently always present in a stack backtrace if dump_stack() gets
called from report_bug():

 [<000000000001517a>] show_trace+0x92/0xe8)
 [<0000000000015270>] show_stack+0xa0/0xd0

This follows a suggestion from Chuck Ebbert on how to make seccomp

seccomp is in terms of the bzImage size that becomes a few bytes (perhaps
even a few kbytes) larger, measure it if you care in the embedded.

Vasily Tarasov b716395e2b diskquota: 32bit quota tools on 64bit architectures
OpenVZ Linux kernel team has discovered the problem with 32bit quota tools
working on 64bit architectures.  In 2.6.10 kernel sys32_quotactl() function
was replaced by sys_quotactl() with the comment "sys_quotactl seems to be
32/64bit clean, enable it for 32bit" However this isn't right.  Look at
if_dqblk structure:

struct if_dqblk {
        __u64 dqb_bhardlimit;
        __u64 dqb_bsoftlimit;
        __u64 dqb_curspace;
        __u64 dqb_ihardlimit;
        __u64 dqb_isoftlimit;
        __u64 dqb_curinodes;
        __u64 dqb_btime;
        __u64 dqb_itime;
        __u32 dqb_valid;
};

For 32 bit quota tools sizeof(if_dqblk) == 0x44.
But for 64 bit kernel its size is 0x48, 'cause of alignment!
Thus we got a problem. Attached patch reintroduce sys32_quotactl() function,
that handles this and related situations.

Dan Williams 1b0fac4587 dma-mapping: prevent dma dependent code from linking on !HAS_DMA archs
Continuing the work started in 411f0f3edc ...

This enables code with a dma path, that compiles away, to build without
requiring additional code factoring.  It also prevents code that calls
dma_alloc_coherent and dma_free_coherent from linking whereas previously
the code would hit a BUG() at run time.  Finally, it allows archs that set
!HAS_DMA to delete their asm/dma-mapping.h file.

Jeff Dike e4c4bf9968 uml: Eliminate kernel allocator wrappers
UML had two wrapper procedures for kmalloc, um_kmalloc and um_kmalloc_atomic
because the flag constants weren't available in userspace code.
kern_constants.h had made kernel constants available for a long time, so there
is no need for these wrappers any more.  Rather, userspace code calls kmalloc
directly with the userspace versions of the gfp flags.

kmalloc isn't a real procedure, so I had to essentially copy the inline
wrapper around __kmalloc.

vmalloc also had its own wrapper for no good reason.  This is now gone.

Jeff Dike 42a359e31a uml: SIGIO support cleanup
Cleanup of the SIGWINCH support.

Some code and comment reformatting.

The stack used for SIGWINCH threads was leaked.  This is now fixed by storing
it with the pid and other information, and freeing it when the thread is
killed.

If something goes wrong with a WIGWINCH thread, and this is discovered in the
interrupt handler, the winch record would leak.  It is now freed, except that
the IRQ isn't freed.  This is hard to do from interrupt context.  This has the
side-effect that the IRQ system maintains a reference to the freed structure,
but that shouldn't cause a problem since the descriptor is disabled.

register_winch_irq is now much better about cleaning up after an
initialization failure.

enable_chan now returns a status and this is passed up to con_open and

The default host device for the serial line driver is now a pts device rather
than a pty device since lots of hosts have LEGACY_PTYS disabled.  This had
always been failing on such hosts, but silently.

DEBUG_SHIRQ generates spurious interrupts, triggering handlers such as
mconsole_interrupt() or line_interrupt().  They expect data to be available to
be read from their sockets/pipes, but in the case of spurious interrupts, the
host didn't actually send anything, so UML hangs in read() and friends.
Setting those fd's as O_NONBLOCK makes DEBUG_SHIRQ-enabled UML kernels boot

David Howells 54a3bdd76e FRV: Remove some dead code
Remove some dead chunks of code that are bounded by preprocessor conditionals
controlled by apparently no-longer available config options.

These are:

	CONFIG_BLK_DEV_BLKMEM
	CONFIG_CHR_DEV_FLASH
	CONFIG_BLK_DEV_FLASH
	CONFIG_CONSOLE

David Howells 769259160a FRV: Be (self-)consistent and use CONFIG_GDB_CONSOLE everywhere
Be (self-)consistent and use CONFIG_GDB_CONSOLE everywhere rather than using
CONFIG_GDBSTUB_CONSOLE in some places and not others.  This is also then
consistent with other archs.

Also remove the gdbstub console device() op which doesn't seem to be necessary
now (especially as it doesn't compile).

Yinghai Lu 18a8bd949d serial: convert early_uart to earlycon for 8250
Beacuse SERIAL_PORT_DFNS is removed from include/asm-i386/serial.h and
include/asm-x86_64/serial.h.  the serial8250_ports need to be probed late in
serial initializing stage.  the console_init=>serial8250_console_init=>
register_console=>serial8250_console_setup will return -ENDEV, and console
ttyS0 can not be enabled at that time.  need to wait till uart_add_one_port in
drivers/serial/serial_core.c to call register_console to get console ttyS0.
that is too late.

Make early_uart to use early_param, so uart console can be used earlier.  Make
it to be bootconsole with CON_BOOT flag, so can use console handover feature.
and it will switch to corresponding normal serial console automatically.

new command line will be:
	console=uart8250,io,0x3f8,9600n8
	console=uart8250,mmio,0xff5e0000,115200n8
or
	earlycon=uart8250,io,0x3f8,9600n8
	earlycon=uart8250,mmio,0xff5e0000,115200n8

it will print in very early stage:
	Early serial console at I/O port 0x3f8 (options '9600n8')
	console [uart0] enabled
later for console it will print:
	console handover: boot [uart0] -> real [ttyS0]

David S. Miller 9918cc2e32 [SPARC64]: Give more accurate errors in dr_cpu_configure().
When cpu_up() fails, we can discern the most likely cause.

If cpu_present() is false, this means the cpu did not appear
in the MD.  If -ENODEV is the error return value, then
the processor did not boot properly into the kernel.

Pass this information back in the dr-cpu response packet.

David S. Miller 39dd992aee [SPARC64]: Clear cpu_{core,sibling}_map[] in smp_fill_in_sib_core_maps()
When we hot-plug in new cpus, the core_id and proc_id of existing
cpus can change.  So in order to set the cpu groups correctly we
need to clear the maps out completely first.

Take a page from the powerpc folks and just calculate the
delay factor directly.

Since frequency scaling chips use a system-tick register,
the value is going to be the same system-wide.

David S. Miller 27a2ef382c [SPARC64]: SMP build fixes.
With the move of ldom_startcpu_cpuid() into smp.c some other
things need to follow along:

1) smp.c is not a driver so we can't use "PFX" macro in the
   printk calls.

2) smp.c now needs asm/io.h and asm/hvtramp.h, ds.c no longer
   does

3) kimage_addr_to_ra() also needs to move into smp.c

While we're here, update copyright info and my email address
in smp.c

David S. Miller b14f5c100c [SPARC64]: Fix build regressions added by dr-cpu changes.
Do not select HOTPLUG_CPU from SUN_LDOMS, that causes
HOTPLUG_CPU to be selected even on non-SMP which is
illegal.

Only build hvtramp.o when SMP, just like trampoline.o

Protect dr-cpu code in ds.c with HOTPLUG_CPU.

Likewise move ldom_startcpu_cpuid() to smp.c and protect
it and the call site with SUN_LDOMS && HOTPLUG_CPU.
