Next two patches provide code for purgatory. This is a code which does
not link against the kernel and runs stand alone. This code runs between
two kernels. One of the primary purpose of this code is to verify the
digest of newly loaded kernel and making sure it matches the digest
computed at kerne
Currently the VSC has no chance to notify the VSP of the dirty rectangle on VM

I have added two more functions to walk through resources.

This is the new syscall kexec_file_load() declaration/interface. I have

This patch adds support for loading a kexec on panic (kdump) kernel usning
new system call.
It prepares ELF headers for memory areas to be dumped and for saved cpu
registers. Also prepares the memory map for second kernel and limits its
boot to reserved areas only.

Hi,
This is V4 of the patchset. Previous versions were posted here.

This patch does two thigns. It passes EFI run time mappings to second

new mappings in second kernel. That means mappings in first and second

Thanks for the clarification Alex, That’s exactly my point, why are we relying
on QEMU or something else to emulate the MSI space when we can directly give
access to devices using ITS (of course with a small emulation code).

The int_ret_from_sys_call and syscall tracing code disagrees with
the sysret path as to the value of RCX.
The Intel SDM, the AMD APM, and my laptop all agree that sysret
returns with RCX == RIP. The syscall tracing code does not respect
this property.
For example, this program:
int main()
{
This patch defines maximum block number to 2^31.
It also converts bitmap_size and array_size to
unsigned int in omfs_get_imap.

MAX77802 is a PMIC that contains 10 high efficiency Buck regulators,
32 Low-dropout (LDO) regulators, two 32kHz buffered clock outputs,
a Real-Time-Clock (RTC) and a I2C interface to program the individual
regulators, clocks and the RTC.
This fifth version of the patch-set addresses several issues
From: Doug Anderson
The max77686 includes an RTC that keeps power during suspend. It's
convenient to be able to use it as a wakeup source.
NOTE: due to wakeup ordering problems this patch alone doesn't work so
well on exynos5250-snow. You also need something that brings the i2c
bus up before t
Like most clock drivers, the Maxim 77686 PMIC clock binding
follows the convention that the "#clock-cells" property is
used to specify the number of cells in a clock provider.
But the binding document is not clear enough that it shall
be set to 1 since the PMIC support multiple clocks outputs.

This patch adds a dt-binding include for Maxim 77686
PMIC clock IDs that can be to be shared between the
clk-max77686 clock driver and DeviceTree source files.

Some device drivers using the register map API need to copy the

Maxim Integrated Power Management ICs are very similar with
regard to their clock outputs. Most of the clock drivers for
these chips are duplicating code and are simpler enough that
can be converted to use a generic driver to consolidate code
