      uml: fix aio compilation bug · da3e30e7
      Jeff Dike authored 
      Restructure do_aio thanks to commments from Ulrich and Al.

Uli started this by seeing that UML's initialization of a struct iocb
initialized fields that it shouldn't.

Al followed up by adding the following cleanups:
	eliminating a variable by just using an anonymous structure in
its place.
	hoisting a duplicated line out of the switch.
	simplifying the error checking at the end.

I added a severity to the printk.

      uml: fix string exporting on UML/i386 · 1a65f493
      Jeff Dike authored 
      In 2.6.23-rc1, i386 fiddled its string support such that UML started getting
undefined references from modules.  The UML asm/string.h was including the
i386 string.h, which defined __HAVE_ARCH_STR*, but the corresponding
implementations weren't being pulled in.

This is fixed by adding arch/i386/lib/string.h to the list of host
architecture files to be pulled in to UML.

A complication is that the libc exports file assumed that the generic strlen
and strstr weren't in use (i.e.  __HAVE_ARCH_STR is defined), then they aren't
exported.  This is untrue for strlen, which is exported in either case, so
this logic is not needed.

      fallocate syscall interface deficiency · 0d786d4a
      Ulrich Drepper authored 
      The fallocate syscall returns ENOSYS in case the filesystem does not support
the operation and expects the userlevel code to fill in.  This is good in
concept.

The problem is that the libc code for old kernels should be able to
distinguish the case where the syscall is not at all available vs not
functioning for a specific mount point.  As is this is not possible and we
always have to invoke the syscall even if the kernel doesn't support it.

I suggest the following patch.  Using EOPNOTSUPP is IMO the right thing to do.

      Use resource_size_t for serial port IO addresses · 4f640efb
      Josh Boyer authored 
      At present, various parts of the serial code use unsigned long to define
resource addresses.  This is a problem, because some 32-bit platforms have
physical addresses larger than 32-bits, and have mmio serial uarts located
above the 4GB point.

This patch changes the type of mapbase in both struct uart_port and struct
plat_serial8250_port to resource_size_t, which can be configured to be 64
bits on such platforms.  The mapbase in serial_struct can't safely be
changed, because that structure is user visible.
