- target/i386: Change wrong XFRM value in SGX CPUID leaf
- target/i386: Enable support for XSAVES based features
- target/i386: Add kvm_get_one_msr helper

- qemu-options.hx: Don't claim "-serial" has limit of 4 serial ports Before v2.12, the implementation of serial ports was limited to a value of MAX_SERIAL_PORTS = 4. We now dynamically allocate the data structures for serial ports, so this limit is no longer present, but the documentation for the -serial options still reads:
- target/ppc: Modify the uncorrect value irq to n_IRQ
- block-migration: Ensure we don't crash during migration cleanup

Subject: [PATCH] block/parallels: Fix buffer-based write call mainline
inclusion commit eba088f91d21d9e42a81bef847173da30c5da961 category: bugfix
---------------------------------------------------------------
Commit a4072543ccdddbd241d5962d9237b8b41fd006bf has changed the I/O here
from working on a local one-element I/O vector to just using the buffer
directly (using the bdrv_co_pread()/bdrv_co_pwrite() helper functions
introduced shortly before).
However, it only changed the bdrv_co_preadv() call to bdrv_co_pread() -
the subsequent bdrv_co_pwritev() call stayed this way, and so still
expects a QEMUIOVector pointer instead of a plain buffer. We must
change that to be a bdrv_co_pwrite() call.
Fixes: a4072543ccdddbd241d5962d ("block/parallels: use buffer-based io")
