SYSENTER emulation is broken in several ways:
1. It misses the case of 16-bit code segments completely (CVE-2015-0239).
2. MSR_IA32_SYSENTER_CS is checked in 64-bit mode incorrectly (bits 0 and 1 can
still be set without causing #GP).
3. MSR_IA32_SYSENTER_EIP and MSR_IA32_SYSENTER_ESP are not masked in
legacy-mode.
4. There is some unneeded code.Fix it.

Commit 0dbc6078c06bc0 ('x86, build, pci: Fix PCI_MSI build on !SMP')
introduced the dependency that X86_UP_APIC is only available when
PCI_MSI is false. This effectively prevents PCI_MSI support on 32bit
UP systems because it disables both APIC and IO-APIC. But APIC support
is architecturally required for PCI_MSI.The intention of the patch was to enforce APIC support when PCI_MSI is
enabled, but failed to do so.Remove the !PCI_MSI dependency from X86_UP_APIC and enforce
X86_UP_APIC when PCI_MSI support is enabled on 32bit UP systems.[ tglx: Massaged changelog ]

The Witcher 2 did something like this to allocate a TLS segment index:
struct user_desc u_info;
bzero(&u_info, sizeof(u_info));
u_info.entry_number = (uint32_t)-1;syscall(SYS_set_thread_area, &u_info);
Strictly speaking, this code was never correct. It should have set
read_exec_only and seg_not_present to 1 to indicate that it wanted
to find a free slot without putting anything there, or it should
have put something sensible in the TLS slot if it wanted to allocate
a TLS entry for real. The actual effect of this code was to
allocate a bogus segment that could be used to exploit espfix.The set_thread_area hardening patches changed the behavior, causing
set_thread_area to return -EINVAL and crashing the game.This changes set_thread_area to interpret this as a request to find
a free slot and to leave it empty, which isn't *quite* what the game
expects but should be close enough to keep it working. In
particular, using the code above to allocate two segments will
allocate the same segment both times.According to FrostbittenKing on Github, this fixes The Witcher 2.
If this somehow still causes problems, we could instead allocate
a limit==0 32-bit data segment, but that seems rather ugly to me.Fixes: 41bdc78544b8 x86/tls: Validate TLS entries to protect espfix

The 3.19 merge window saw some TLB modifications merged which caused a
performance regression. They were fixed in commit 045bbb9fa.Once that fix was applied, I also noticed that there was a small
but intermittent regression still present. It was not present
consistently enough to bisect reliably, but I'm fairly confident
that it came from (my own) MPX patches. The source was reading
a relatively unused field in the mm_struct via arch_unmap.I also noted that this code was in the main instruction flow of
do_munmap() and probably had more icache impact than we want.This patch does two things:
1. Adds a static (via Kconfig) and dynamic (via cpuid) check
for MPX with cpu_feature_enabled(). This keeps us from
reading that cacheline in the mm and trades it for a check
of the global CPUID variables at least on CPUs without MPX.
2. Adds an unlikely() to ensure that the MPX call ends up out
of the main instruction flow in do_munmap(). I've added
a detailed comment about why this was done and why we want
it even on systems where MPX is present.Signed-off-by: Dave Hansen

We had originally planned on submitting MPX support in one patch
set. We eventually broke it up in to two pieces for easier
review. One of the features that didn't make the first round
was supporting 32-bit binaries on 64-bit kernels.Once we split the set up, we never added code to restrict 32-bit
binaries from _using_ MPX on 64-bit kernels.The 32-bit bounds tables are a different format than the 64-bit
ones. Without this patch, the kernel will try to read a 32-bit
binary's tables as if they were the 64-bit version. They will
likely be noticed as being invalid rather quickly and the app
will get killed, but that's kinda mean.This patch adds an explicit check, and will make a 64-bit kernel
essentially behave as if it has no MPX support when called from
a 32-bit binary.Signed-off-by: Dave Hansen

Currently Xen Domain0 has special treatment for ACPI SCI interrupt,
that is initialize irq for ACPI SCI at early stage in a special way as:
xen_init_IRQ()
->pci_xen_initial_domain()
->xen_setup_acpi_sci()
Allocate and initialize irq for ACPI SCIFunction xen_setup_acpi_sci() calls acpi_gsi_to_irq() to get an irq
number for ACPI SCI. But unfortunately acpi_gsi_to_irq() depends on
IOAPIC irqdomains through following path
acpi_gsi_to_irq()
->mp_map_gsi_to_irq()
->mp_map_pin_to_irq()
->check IOAPIC irqdomainFor PV domains, it uses Xen event based interrupt manangement and
doesn't make uses of native IOAPIC, so no irqdomains created for IOAPIC.
This causes Xen domain0 fail to install interrupt handler for ACPI SCI
and all ACPI events will be lost. Please refer to:
https://lkml.org/lkml/2014/12/19/178So the fix is to get rid of special treatment for ACPI SCI, just treat
ACPI SCI as normal GSI interrupt as:
acpi_gsi_to_irq()
->acpi_register_gsi()
->acpi_register_gsi_xen()
->xen_register_gsi()With above change, there's no need for xen_setup_acpi_sci() anymore.
The above change also works with bare metal kernel too.Signed-off-by: Jiang Liu

Merge "Urgent omap4 legacy interrupt regression fix for v3.19-rc series" from
Tony Lindgren:A rather urgent pull request to fix omap4 legacy interrupts.
The legacy interrupts on omap4 got broken when gic got changed to
use irq_domain_add_linear() instead of the irq_domain_add_legacy(). We
still have the hardcoded legacy IRQ numbers in use in several places,
most notably the in the legacy DMA. It took a while to figure out
what the problem was and how it should be fixed for the -rc series.Also include is a regression fix for the dra7 dwc3 suspend.
