efi: x86: Wire up IBT annotation in memory attributes table
UEFI v2.10 extends the EFI memory attributes table with a flag that indicates whether or not all RuntimeServicesCode regions were constructed with ENDBR landing pads, permitting the OS to map these regions with IBT restrictions enabled.
So let's take this into account on x86 as well.

APM_DO_POP_SEGS does not restore fs/gs which were zeroed by APM_DO_ZERO_SEGS. Trying to access __preempt_count with zeroed fs doesn't really work.
Move the ibrs call outside the APM_DO_SAVE_SEGS/APM_DO_RESTORE_SEGS invocations so that fs is actually restored before calling preempt_enable().

with de-mangling cleanups yet to come.
NOTE! On almost all architectures, the EPOLL* constants have the same values as the POLL* constants do. But they keyword here is "almost". For various bad reasons they aren't the same, and epoll() doesn't actually work quite correctly in some cases due to this on Sparc et al.
The next patch from Al will sort out the final differences, and we should be all done.

x86: Remap GDT tables in the fixmap section
Each processor holds a GDT in its per-cpu structure. The sgdt instruction gives the base address of the current GDT. This address can be used to bypass KASLR memory randomization. With another bug, an attacker could target other per-cpu structures or deduce the base of the main memory section (PAGE_OFFSET).
This patch relocates the GDT table for each processor inside the fixmap section. The space is reserved based on number of supported processors.
For consistency, the remapping is done by default on 32 and 64-bit.
Each processor switches to its remapped GDT at the end of initialization. For hibernation, the main processor returns with the original GDT and switches back to the remapping at completion.
This patch was tested on both architectures. Hibernation and KVM were both tested specially for their usage of the GDT.
Thanks to Boris Ostrovsky <boris.ostrovsky@oracle.com> for testing and recommending changes for Xen support.

This API returns a task's cputime in cputime_t in order to ease the conversion of cputime internals to use nsecs units instead. Blindly converting all cputime readers to use this API now will later let us convert more smoothly and step by step all these places to use the new nsec based cputime.

Moreover since only 2 task_cputime() calls of 17 use a NULL argument, we can add dummy variables to those calls and remove NULL checks from task_cputimes().
Also remove NULL checks from task_cputimes_scaled().

apm_bios_call() can fail, and return a status in its argument structure. If that status however is zero during a call from apm_get_power_status(), we end up using data that may have never been set, as reported by "gcc -Wmaybe-uninitialized":

This changes the function to return "APM_NO_ERROR" here, which makes the code more robust to broken BIOS versions, and avoids the warning.

x86/apm32: Remove paravirt_enabled() use
There is already a check for apm_info.bios == 0, the apm_info.bios is set from the boot_params.apm_bios_info. Both Xen and lguest, which are also the only ones that set paravirt_enabled to true, never set the apm_bios.info. The
Xen folks are sure force disable to 0 is not needed because apm_info lives in .bss, we recently forced disabled this on lguest, and on the Xen side just to be sure Boris zeroed out the .bss for PV guests through commit 04b6b4a56884327c1648 ("xen/x86: Zero out .bss for PV guests"). With this care taken into consideration the paravirt_enabled() check is simply not needed anymore.
