A non-periodic clock_event_device and the "jiffies" clock don't mix well:
tick_handle_periodic() can go into an infinite loop.Currently lguest guests use the jiffies clock when the TSC is
unusable. Instead, make the Host write the current time into the lguest
page on every interrupt. This doesn't cost much but is more precise
and at least as accurate as the jiffies clock. It also gets rid of
the GET_WALLCLOCK hypercall.Also, delay setting sched_clock until our clock is set up, otherwise
the early printk timestamps can go backwards (not harmful, just ugly).Signed-off-by: Rusty Russell

Jason Yeh sent his crashing .config: bzImages made with
CONFIG_RELOCATABLE=y put the relocs where the BSS is expected, and we
crash with unusual results such as:lguest: unhandled trap 14 at 0xc0122ae1 (0xa9)
Relying on BSS being zero was merely laziness on my part, and
unfortunately, lguest doesn't go through the normal startup path (which
does this in asm).Signed-off-by: Rusty Russell

It is important to only provide the compat_ioctl method
if the downstream de->proc_fops does too, otherwise this
utterly confuses the logic in fs/compat_ioctl.c and we
end up doing the wrong thing.Signed-off-by: David S. Miller

#x blocks expansion of macro argument, but it won't do you any
good if it's already been expanded... As it is, RFALSE(cond, ....)
ended up with stringified _expanded_ cond. Real fun when cond contains
something like le32_to_cpu() and you are on a big-endian box...Signed-off-by: Al Viro

... because somebody had added preempt.h -> list.h, resulting in
asm/system.h -> hardirq.h -> preempt.h -> list.h -> asm/system.h on m68k,
with smp_wmb() used in list.h and defined in asm/system.h below the include

MXC needs the same change as IOP. See [ARM] 4494/1
or commit 7dea1b20066cd30fb54da7e686b16b5e38b46b2dAn undefined reference to elf_hwcap prevents linkage, due
to changes made by f884b1cf578e079f01682514ae1ae64c74586602
and d1cbbd6b413510c6512f4f80ffd48db1a8dd554aRemoving processor.h removes the extern definition of
elf_hwcap, which fixes the link issue, but forgets cpu_relax().
So, instead, we'll call barrier() directly.Cc: Lennert Buytenhek

a compatability issue with 32bit quota tools, but the new compat
routines are only needed when CONFIG_COMPAT=y (and with this set
to 'n' there are compilation problems since some new typedefs are
not visible).Reported by Doug Chapman. Fix tuned by a cast of thousands (Andi,

If a machine check is pending and the external or I/O interrupt handler
returns to userspace io_mcck_pending is going to call s390_handle_mcck.
Before this happens a call to TRACE_IRQS_ON was already made since we
know that we are going back to userspace and hence interrupts will be
enabled. So there was an indication that interrupts are enabled while
in reality they are still disabled.
s390_handle_mcck will do a local_irq_save/restore pair and confuse
lockdep which later complains about inconsistent irq tracing.
To solve this just call trace_hardirqs_off before calling
s390_handle_mcck and trace_hardirqs_on afterwards.Signed-off-by: Heiko Carstens

There is no need to disable bottom halves when holding call_lock. Also
this could imply that it is legal to call smp_call_function* from
bh context, which it is not.
Also test if func will be executed locally before disabling
and aterwards enabling interrupts again. It's not necessary to disable
and enable interrupts each time __smp_call_function_map gets called.Signed-off-by: Heiko Carstens

BLK_DEV_BSG was added outside of the if BLOCK check, which allows it to
be enabled when CONFIG_BLOCK=n. This leads to many screenlengths of
errors, starting with a parse error on the request_queue_t definition.
Obviously this wasn't intended for CONFIG_BLOCK=n usage, so just move the
option back in to the block.Caught with a randconfig on sh.
